How to adjust the temperature of the refrigerator
1. We need to find the temperature control switch of the refrigerator. Some refrigerators have a panel, and the temperature adjustment button is on the temperature control panel. 2. If the refrigerator does not have a temperature control panel, then the adjustment button is inside the refrigerator, usually a roller, on the top or left side of the refrigerator. 3. According to actual measurements, the larger the refrigerator temperature control number, the lower the temperature. It is appropriate to adjust it to 3-4 in spring and autumn; in summer, when the indoor temperature is high, it is appropriate to adjust it to 6-7; in winter, when the temperature is low, it is appropriate to adjust it to level 1-2. 4. Note that the higher the setting, the lower the temperature, but the higher the power consumption. Try not to turn it too high if there is nothing to freeze.
What do the digital knobs in the refrigerator mean?
In fact, this rotary button is the temperature control gear number of the refrigerator. As the name suggests, it is used to control the temperature inside the refrigerator. The larger the corresponding number, the lower the temperature, the better the cooling effect, and at the same time, it consumes more energy and electricity; the smaller the number, the higher the temperature, the smaller the cooling effect, and at the same time, it consumes less energy and saves electricity.
When the outdoor temperature is high in summer, the temperature control can be adjusted to 4-5 gears; in winter, the ambient temperature is low, and the temperature control can be adjusted to 2-3 gears; in spring and autumn, the temperature control can be adjusted to 3-4 gears.
How do you usually maintain your refrigerator?
1. Clean the compressor and condenser regularly
The compressor and condenser are important refrigeration parts of the refrigerator. If they are stained with dust, they will affect heat dissipation, shorten the service life of the parts, and weaken the cooling effect of the refrigerator. Therefore, check them regularly to see if they are dirty and clean them if they are dirty.
Of course, there is no need to consider this issue when using a refrigerator with a completely flat back design. Because the condenser and compressor of the backpack refrigerator are exposed to the outside, it is easy to get dust, spider webs, etc. However, the condenser and compressor of a flat-back refrigerator are built-in, so the above situation will not occur.
2. Clean the inside of the refrigerator regularly
When the refrigerator is used for a long time, the smell will be unpleasant and bacteria may even breed. Therefore, after using it for a period of time, you need to take out the food in the refrigerator and do a "general cleaning". Generally, the inside of the refrigerator needs to be thoroughly cleaned every three months.
How to adjust the refrigerator temperature
1. Mechanical refrigerator temperature adjustment method
The mechanical refrigerator requires manual temperature adjustment. There will be a circular rotary switch in the cold storage compartment of the refrigerator, with numbers from 0 to 7 marked on it. 0 is the inactive state. The larger the number, the stronger the cooling. 7 is the intensity of cooling. Just turn the button to adjust the temperature. Generally, the temperature is 1~3 in summer, 3~4 in spring and autumn, and 4~5 in winter.
2. Smart refrigerator adjustment method
1. Default adjustment
Artificial intelligence refrigerators generally adjust the temperature intelligently by default and do not need to be set by yourself. If the artificial intelligence is not turned on, in the unlocked state, you can press the artificial intelligence button on the refrigerator panel, and the icon E will be displayed, and the refrigerator will enter the artificial intelligence state. Press the smart button again, the icon E will disappear, and the intelligent adjustment state will exit.
2. Manual adjustment
Artificial intelligence refrigerators can also be adjusted manually. In the non-locked, non-artificial intelligence state, press the refrigeration adjustment button, and the flashing icon F will be displayed on the panel. Each time you press the refrigeration adjustment button, the temperature will drop by 1℃ until 3℃. Press it again and it will return to 7℃. The temperature can beChanging between 3℃ and 7℃, the setting is successful if there is no button pressed within 5 seconds after operation.
3. Freezing adjustment
The freezing temperature adjustment adopts the same method, except that the button is changed to the freezing adjustment button, and the flashing icon is H. Each time the freezing adjustment button is pressed, the freezing set temperature decreases by 1°C until -22°C. Press the freezing adjustment button again, and the freezing temperature returns to -15°C. The temperature can be changed between -15°C and -22°C.
Summer temperature adjustment
During the use of the refrigerator, its working time and power consumption are greatly affected by the ambient temperature, so we need to choose different gears in different seasons. When the ambient temperature is high in summer, it should be used in weak gear 2-3.
Because in summer, the ambient temperature is high, and it is very difficult for the temperature inside the box to drop by 1 degree at this time. The loss of cold energy through the box insulation layer and door seal will also accelerate, so the startup time will be long and the shutdown time will be short. This will cause the press to run at high temperatures for a long time, aggravating the wear of the piston and cylinder. The insulation performance of the motor coil enameled wire will also be reduced due to high temperature, and the power consumption will also rise sharply, which is uneconomical and unreasonable.
How to adjust the refrigerator temperature correctly
I believe many friends have encountered the problem of not knowing how to adjust the temperature of the refrigerator at home. Let’s take a look at how to adjust the refrigerator temperature with me.
The correct method to adjust the temperature of household refrigerators
The recommended temperatures in the fresh food area are 2, 7-4, 4℃, and the temperature in the freezer is -15℃. If there is a separate freezer for long-term storage of food, it is best to keep its temperature at -17°C. For example, the refrigeration temperature for fresh meat and fish is about -1 degree, the refrigeration temperature for eggs and milk is about 3 degrees, and the refrigeration temperature for vegetables and fruits is about 5 degrees.
The refrigerator temperature control knobs are marked with numbers, which represent the control range of the temperature in the refrigerator. The larger the marked number, the higher the control temperature. The indication range of the thermostat in different seasons is: 2 to 3 in summer; 3 to 4 in spring and autumn; 4 to 5 in winter. When the room temperature is lower than 10°C, the thermostat should be set to the "6" position.
How to adjust the thermostat knob: The refrigerator temperature control knob generally has 0, 1, 2, 3, 4, 5, 6, and 7 levels. The larger the number, the lower the temperature in the freezer. Generally, we put it on level 3 in spring and autumn. It depends on your requirements, whether the freezer can reach below minus 18 degrees. In order to achieve the purpose of food preservation and power saving, we can set it to 2nd or 3rd gear in summer and 4th or 5th gear in winter. Some people may ask, if the temperature is low in winter, but the temperature is set low (the thermostat value is large), and in summer, when the temperature is high, the temperature is set high (the thermostat value is small), is it the other way around? In fact, many people have this misunderstanding. They believe that the temperature of the refrigerator should be set higher when the temperature is low in winter, and lower when the temperature is high in summer. Why should the refrigerator thermostat be set like this? Because the temperature of the refrigerator freezer is controlled by the temperature in the storage room. Your temperature control knob is in the storage room. The temperature in the storage room is generally between 4 and 8 degrees. In winter, the indoor temperature is close to this temperature. If the thermostat knob is still at 3 or less, the refrigerator compressor will rarely start. Although the temperature in the storage room can meet the requirements, the temperature in the freezer cannot reach below minus 18 degrees. Food is easy to deteriorate, and in severe cases, the food thaws and melts. It’s summerDuring the day, the temperature is relatively high. If the thermostat knob is still at 3 or higher, the compressor in the refrigerator storage room will start frequently in order to meet the temperature requirements. Although the temperature in the freezer is lower than minus 18 degrees, it will cause a waste of electric energy and shorten the service life of the refrigerator, which is what we do not want. Therefore, correctly adjusting the refrigerator temperature controller knob can keep us fresh and save energy.
Unless the temperature in your home is like spring all year round, then there is no need to change the temperature of your refrigerator. Otherwise, due to the large temperature difference between summer and winter, in order to save power and ensure the quality of food freezing, it is necessary to adjust the temperature control knob of the refrigerator in summer and winter.
Adjustment method: The temperature control knob generally has 0, 1, 2, 3, 4, 5, 6, and 7. The larger the number, the lower the temperature in the freezer. Generally, we put it on level 3 in spring and autumn. It depends on your requirements, whether the freezer can reach below minus 18 degrees. In order to achieve the purpose of food preservation and power saving, we can set the 1st or 2nd level in summer, and the 4th or 5th level in winter.
Some people may ask, if the temperature is low in winter, the temperature is set low (the value is large), and in the summer when the temperature is high, the temperature is set high (the value is small). Is it the other way around? In fact, many people have this misunderstanding. They believe that the temperature of the refrigerator should be set higher when the temperature is low in winter, and lower when the temperature is high in summer. Why should I set it like this? That's because the temperature of the refrigerator and freezer is controlled by the temperature in the storage room. Your temperature control knob is in the storage room. The temperature in the storage room is generally 4 to 8 degrees. In winter, the indoor temperature is close to this temperature. If the temperature control knob is still at 3 or less than 3, the refrigerator compressor will rarely start. Although the temperature in the storage room can meet the requirements, the temperature in the freezer cannot reach below minus 18 degrees. Food is easy to deteriorate, and in severe cases, the food thaws and melts. In summer, the temperature is relatively high. If the temperature control knob is still at 3 or higher, the compressor in the refrigerator storage room will start frequently in order to meet the temperature requirements. Although the temperature in the freezer is lower than minus 18 degrees, it will cause a waste of electric energy and shorten the service life of the refrigerator, which is what we do not want. Therefore, correctly adjusting the refrigerator temperature control knob can keep us fresh and save energy.
Energy-saving tips for household refrigerator temperatures
1. Temperature adjustment in summer
When a refrigerator (freezer) is in use, its working time and power consumption are greatly affected by the ambient temperature, so we need to choose different gears in different seasons. When the ambient temperature is high in summer, it should be used in weak gear 2-3.
Cause: In summer, the ambient temperature is high, and it is very difficult for the temperature inside the box to drop by 1 degree at this time. The loss of cold energy through the box insulation layer and door seal will also accelerate, so the startup time will be long and the downtime will be short. This will cause the press to run at high temperatures for a long time, aggravating the wear of the piston and cylinder. The insulation performance of the motor coil enameled wire will also be reduced due to high temperature, and the power consumption will also rise sharply, which is uneconomical and unreasonable. If you change to the weak gear (2, 3) at this time, you will find that the startup time is obviously shortened and the shutdown time is lengthened. This not only saves electric energy, but also reduces the wear and tear of the compressor and extends the service life. Therefore, when the temperature is high in summer, adjust the thermostat to a weak setting.
2. Winter temperature adjustment
In winter, it is generally applicable to set the gear to 4 or above. The reason is: the product you purchased has only one refrigeration room thermostat to control the refrigeration and freezing temperatures, because the refrigeration temperature technical requirements are controlled between 0 and 10 degrees, and generally in winterIn season, the refrigeration environment is relatively low, and it is easy for refrigeration to reach the set temperature. If the set temperature is too high, it is easy to cause the refrigerator to be turned on for a short time, resulting in insufficient freezing and cooling effects. In winter, if the ambient temperature is low, the main purpose is to ensure the cooling effect of freezing. Generally speaking, if the ambient temperature is lower than 16 degrees, adjust it to level 5, and if it is lower than 10 degrees, you can adjust it to level 6 or 7. Sometimes because the ambient temperature is too low, such as 0~5 degrees, the gear is lowered and the food is refrigerated. At this time, the food can be stored outside the refrigerator
3. Low temperature compensation switch switch
The product system you purchased is a single-system refrigerator with only one refrigerator compartment. A thermostat is used to control the temperature of refrigeration and freezing. Because the refrigeration temperature technology requires the temperature to be controlled between 0 and 10 degrees, when the ambient temperature is close to the temperature of the storage room, the refrigeration will reach the temperature in a short time or even without turning on. The phenomenon of the refrigerator not turning on or taking a short time to turn on the refrigerator will not reach the freezing temperature. In order to prevent the refrigerator from not being turned on or being turned on for a short time in winter, the production department specially designed a low temperature compensation or switching device for single-system refrigerators. This device is used to ensure that the refrigerator can operate normally even when the ambient temperature is low in winter. Therefore, when the ambient temperature is lower than 16 degrees, the low temperature compensation or switching switch needs to be turned on (see the instructions for details). Also note that the ambient temperature cannot be lower than 10 degrees, and adjust the thermostat to a strong position.
Guidelines for adjusting the temperature of refrigerators in summer
People are accustomed to believe that the ambient temperature in summer is higher and food is prone to spoilage, so the internal temperature of the refrigerator should be adjusted lower. However, from the perspective of short-term food preservation and power saving, the temperature in the refrigerator should not be too low. The freezing temperature of a three-star refrigerator can be controlled at minus 18 degrees Celsius, and the average temperature of the refrigerator compartment is 5 degrees Celsius. This is the temperature achievable at design time. At this temperature, frozen food can be kept fresh for about 3 months, and in actual use, the internal temperature of the refrigerator can be adjusted as needed. In summer, if we still adjust the internal temperature very low, the temperature difference between the inside and outside of the refrigerator will increase, which is not only detrimental to the normal use of the refrigerator, but also does not fundamentally improve food preservation, but increases power consumption. It is better to increase the temperature in the refrigerator appropriately, such as raising the temperature of the freezer to minus 15 degrees Celsius and adjusting the average temperature of the refrigerator compartment to about 7 degrees Celsius. At this time, the frozen food can still be kept fresh for 1 to 8 months. It can be seen that when the temperature is high in summer, if the temperature of the refrigerator is appropriately raised, it will not affect the short-term preservation and storage of food, but also save electricity. It can be said that it kills two birds with one stone.
Top ten mistakes in using refrigerators
1. Food packaging bags are not sealed carefully
Improper sealing can easily cause air and moisture to enter, leading to food spoilage.
Corrective measures: When storing food, be sure to tighten the lid or squeeze the air out of the plastic bag, and then tie the seal. If the plastic wrap cannot seal the mouth of the container, it is best to tie it with a rubber band.
2. Do not change the original packaging and put it directly in the refrigerator
Foods such as meat, cut vegetables and fruits packaged in plastic wrap may seem to be tightly wrapped, but in fact there may be air leaks that are difficult to detect with the naked eye.
Corrective measures: If you do not eat food packaged in plastic wrap for a while after buying it home, you should remove the original packaging, repackage it in a clean plastic bag or plastic wrap, and then put it in the refrigerator.
3. Storage containers that are too large
Having too little food but too large a container can easily cause the surface of the food to harden and accelerate its spoilage.
Corrective measures: Food and storage containers should match as much as possible, leaving as small a gap as possible.
4. Do not store large pieces of food separately.
If large pieces of food such as pigs, cattle, and sheep are not stored separately, they cannot be eaten at one time. If they are repeatedly thawed next time, it will easily accelerate the deterioration of the food.
Corrective measures: Divide large portions of food into portions that can be eaten at one time, wrap them separately and store them separately.
5. Not paying attention to the refrigerator temperature
A slightly higher refrigerator temperature may cause certain foods to spoil faster.
Corrective measures: The temperatures of the refrigerator compartment and freezer should be below 4°C and minus 18°C respectively.
6. Recycling of plastic takeout boxes
Many people are reluctant to throw away plastic takeout boxes and other containers and use them repeatedly. But these boxes are not strong, and if they are damaged, the food will spoil quickly.
Corrective measures: Throw away take-out boxes after use, use new containers when serving food, and make sure they are not damaged.
7. Placing food randomly on the refrigerator door
The temperature on the refrigerator door is usually slightly higher than the temperature on the inner shelf of the refrigerator, causing the food to spoil faster.
Corrective measures: Perishable foods such as eggs, milk and fresh cooked foods should be placed on shelves or boxes inside the refrigerator.
8. Put food that is too hot into the refrigerator
Do not put food in the refrigerator when it is too hot. Otherwise, it will cause damage to the refrigerator and easily cause bacteria to breed in the surrounding food due to the increase in temperature.
Corrective measures: It is best to let warm food cool before putting it in the refrigerator. You can refrigerate large boxes of warm food by adding ice cubes or dividing them into smaller portions for storage.
9. Leftovers in the refrigerator are not labeled
Leftovers are easily forgotten after being placed in the refrigerator. This type of food is more likely to spoil even if it is refrigerated.
Corrective measures: When putting leftovers in the refrigerator, it is best to label them and indicate the date. Once expired, throw it away immediately.
10. Determine whether food has expired by smell alone
Many people do not know the shelf life of food and judge whether food has spoiled by smell alone. In fact, food that has no taste may have gone bad. Food contaminated with Listeria monocytogenes will not change its color, flavor or taste.
Corrective measures: Pay attention to the best before date on the packaging. The best way to tell if food has gone bad is by its appearance and feel. If the meat becomes discolored, sticky, or the packaging swells, throw it away immediately.
Analysis of the reasons why the refrigerator is not cooling
1. The high-pressure output buffer pipe in the compressor is broken, or the screws fixing the pipe are loose, causing the high-pressure pipe to not exhaust air and the low-pressure pipe to not suck air. Therefore, although the compressor is running, it is not cooling.
2. The refrigeration system leaks and all the refrigerant is gone. Although the compressor is running, there is no refrigerant in the system to evaporate and absorb heat, so the temperature inside the refrigerator does not drop.
3. The capillary tube is blocked and the refrigerant cannot enter the evaporator to evaporate and absorb heat, so the temperature inside the refrigerator does not drop.
How to troubleshoot a refrigerator that is not cooling
1. Cut the casing, replace the buffer tube, or tighten the screws.
2. First find out the leakage part of the system, carry out welding repair, pressure test and evacuation. After passing the evacuation, add refrigerant to a certain amount, usually based on the fact that the evaporator is full of frost or the refrigerator reaches the rated temperature.
3. The capillary tube or dryer is clogged, and the outlet is hot. For this reason, it must be removed and cleaned! In addition, household refrigerators generally have two types: direct cooling type and indirect cooling type. The direct cooling type refers to the evaporator (cooling tube)It directly exchanges heat with the freezing and refrigeration rooms to achieve cooling; the intercooling type means that the evaporator (cooling tube) is separated from the freezing and refrigeration rooms, and a fan blows cold air into the freezing and refrigeration rooms to achieve cooling.
Your refrigerator is not cooling. You should judge from the following aspects:
1: Check whether the power connection is normal.
Open the door of the box and observe whether the light inside the box is on, or test it with an electric pen.
2: If the power connection is normal, listen to see if the compressor is working.
When the compressor is working normally, it will emit slight and vibrating motor sounds (if you feel the vibration of the compressor with your hands, you should be careful not to get burned, because the compressor temperature is 40-50°C in winter and can reach 80-90°C in summer).
3: If the compressor can work, determine whether there is refrigerant (commonly known as potion) in the refrigeration system.
Let the refrigerator run for a few minutes, then unplug it and listen carefully for the sound of liquid flowing in the copper pipe. If not, it means that the refrigerant in the system has leaked, or the compressor has lost its working ability.
4: If your refrigerator is of the intercooling type, check whether the fan is working.
Open the door of the freezer, press the button on the edge of the box with your hand (this button controls the indoor lighting and stops the fan when the door is opened), and check whether the fan is working. If the fan is not working, the refrigerator will not cool.
On the other hand, placing too much food in the box will also affect the cooling effect.
Inspection of common faults of the refrigerator not cooling
1. The refrigerator is not cooling: whether the power plug of the refrigerator is plugged in; whether the power socket has power; whether the power circuit breaker is disconnected. Check whether the refrigerator door light is on to determine whether the refrigerator is connected to power. Check whether the thermostat is in the working gear. The thermostat has a stop gear (0 gear). The compressor will not work if it is placed in the stop gear. If the above items are normal, please contact maintenance personnel to solve the problem.
2. The refrigerator is not cooling well: Check whether the thermostat is set too low. Whether there is too much food stored or overheated food. Whether the door is frequently opened or the door is not tightly sealed. Is it exposed to direct sunlight or a heat source near the refrigerator? Is there poor ventilation around the area? Check whether the ambient temperature is too low and the temperature compensation switch is not turned on.
3. The refrigerator makes noise and cannot start: Under normal ambient temperature (15℃-38℃), when the refrigerator starts, if the compressor makes a "buzzing" sound and stops working in about half a minute, this situation is due to the power supply voltage being too low (lower than 187V). The compressor cannot start; if the compressor makes a "hmm" sound and then hears a "click" sound, this situation is caused by the power supply voltage being too high (higher than 242V) or the compressor working continuously for too long; when the power supply voltage returns to normal or the compressor shell temperature decreases, the refrigerator can work normally.
4. The door seal is not tight: The main reason for the gap between the refrigerator door seal and the box is the deformation of the door seal. You can use a hair dryer (power 300W) to blow the deformed concave part to restore it to its original shape and eliminate the gap. However, please note that the power of the hair dryer should not be too high, the hot spots should not be too concentrated, and the blower outlet should not be too close to the deformed door seal, otherwise the door seal will be damaged. In addition, placing a thin sponge under the recessed area of the door seal where it meets the door can also eliminate gaps. If the above correction is ineffective, the strip should be replaced with a new one.
5. Water accumulation or water overflow in the refrigerator compartment: The drainage hole in the refrigerator compartment is blocked, causing the condensed water to not be drained smoothly. Use a flexible tool to clear it.
How to finishNot cold at all?
1. Is there a power outage?
2. Is the power plug of the refrigerator loose?
3. Is the non-fuse power switch in the home tripped or are the fuses of other switches broken?
Insufficient cooling?
1. Is hot food put in or the refrigerator door is opened and closed frequently;< /p>
2. Is there too much food in the refrigerator?
3. Is there any problem with the installation, and is the heat sink behind the refrigerator blocked?
How can condensation occur on the outside of the refrigerator?
The refrigerator is used in places with a lot of moisture, and there may be condensation on the outside. This is not a malfunction. Just wipe it with a dry cloth and maintain ventilation around it.
Is the food on the lower floor frozen?
1. Please check whether the temperature control switch or the lower damper switch and the knob switch are in the appropriate position.
2. Whether the temperature of the installation site is below 5 degrees Celsius.
3. Do you put food that contains too much water and is easy to freeze on the inside of the fence?
Three major precautions for refrigerator temperature adjustment
1. The importance of refrigerator temperature adjustment: When the temperature difference between winter and summer is large, it is time to adjust the temperature of the refrigerator at home.
The weather changes in a year are divided into spring, summer, autumn and winter, and the temperature also changes with the change of the weather. The influence of the outside temperature will naturally affect the temperature inside the refrigerator. Or your home is similar to Hainan and has only one season a year. In this case, you do not need to adjust the temperature of the refrigerator in your home according to the changes in the weather. However, when the temperature difference between winter and summer is large, it is the most time to adjust the temperature of the refrigerator in your home, so as to save energy and ensure the quality of food freezing.
2. How to adjust the temperature of the refrigerator to save more energy?
The temperature control optional buttons of the refrigerator are basically 0, 1, 2, 3, 4, 5, 6, and 7. The larger the number, the lower the temperature of the refrigerator compartment. In general, in spring and autumn, we only need to adjust the refrigerator temperature to between 3 o'clock and 1 o'clock in the summer, so as to achieve better energy-saving and electricity-saving effects.
3. Be wary of wrong refrigerator temperature adjustment methods to prevent damage to the compressor!
Some people may have such a wrong adjustment method, adjusting the refrigerator temperature very low in winter, and adjusting the refrigerator temperature very high in summer. They think that the temperature of the refrigerator freezer also decreases with the decrease of the ambient temperature. As the ambient temperature increases, the refrigerator freezer also increases, which can better achieve the effect of saving electricity. This is actually a wrong approach. When our ambient temperature drops to a very low temperature, the refrigerator compressor will stop working if the temperature of your refrigerator is still at around level 3. However, at this time, the temperature of your refrigerator compartment has actually not reached the normal cooling temperature. In order to reach the normal refrigerator temperature of 18 degrees, the refrigerator compressor will start and shut down frequently. At this time, not only cannot it save electricity, but it will cause excessive consumption of electric energy and cause more serious damage to the compressor.
IV. Precautions for summer refrigerator temperature adjustment and winter refrigerator temperature adjustment
Everyone must pay special attention to the fact that summer refrigerator temperature adjustment and winter refrigerator temperature adjustment are two completely different aspects. When adjusting the temperature in summer, because the refrigerator is in use, its working time and power consumption are affected byThe ambient temperature has a great influence, so we need to choose different gears in different seasons. When the ambient temperature is high in summer, the temperature should be adjusted between level 1 and level 2. In winter, adjust the temperature to above level 4. At the same time, when adjusting the temperature of the refrigerator, you should adjust the refrigerator temperature based on the ambient temperature of your home.
