1. What is the cause of freezing in the refrigerator compartment of the refrigerator?
It is normal for the rear wall of the refrigerator compartment to freeze, the evaporator is inside the rear wall of the refrigerator compartment, and the compressor is working When the temperature of the evaporator is very low, it cools down the refrigerator room, so there will be frost and ice formation. After the compressor is stopped, the frost and ice will slowly melt and form water droplets, which flow to the connection below. In the water box, it is then discharged into the water receiving box above the compressor through the drain hole, and slowly evaporated by the high temperature of the compressor. If the rear wall is always frozen and the compressor does not stop for a long time, it is caused by the temperature of the refrigerator being adjusted too low, and the gear of the thermostat should be lowered. If the compressor does not stop working for a long time, it means that there is a problem with the thermostat, and the product should be returned and exchanged.
1. If the temperature of the refrigerator compartment is adjusted too low, it will cause the freezer compartment of the refrigerator to freeze. The temperature of the refrigerator compartment should be designed between 4-8 degrees. It is necessary to make reasonable adjustments according to the seasonal temperature. In summer, the gear should be adjusted to 1-2, spring and autumn should be adjusted to 3, and winter should be adjusted to 4-5. Keep the temperature of the freezer room at about minus 18 degrees and the temperature of the refrigerator room at 0-10 degrees. between, preferably between 6-8 degrees.
2. Under long-term use, the seal of the refrigerator door is prone to laxness. The lax seal of the refrigerator door will cause serious loss of cold air in the refrigerating room. If the sealing strip is not tightly sealed, it should be repaired or replaced with a new door seal in time, and the number or time of opening the door should be minimized at ordinary times.
3. The thermostat itself is faulty, which causes the compressor to work for a long time without stopping.
Second, what should I do if the refrigerator freezer freezes?
Symptom 1: The freezer compartment of the refrigerator repeatedly freezes
Solution: Check the temperature of the refrigerator first. The general temperature is adjusted between 3 and 4 degrees. If the temperature is not within this range, this phenomenon may occur. If the temperature is not the problem, check the food stored in the refrigerator to see if the temperature is too high. Avoid placing food that is too hot in the refrigerator. The hot air will cause a lot of condensation and indirectly cause this phenomenon. Excluding these two problems, then it may be caused by damage to the thermostat.
Phenomena 2: Old refrigerator freezer does not cool after freezing
Solution: This phenomenon is generally caused by refrigerant leakage. Initially, you can listen to whether the sound of the compressor is running at a lower volume than usual. If so, test the temperature of the condenser again. When the temperature is low, it can be judged that it is the cause of insufficient refrigerant. At this time, only the refrigerant needs to be added. If you do not know how to add refrigerant, you can directly contact the maintenance and after-sales service. (Browse down to check the after-sales phone number of the corresponding brand.)
Phenomena 3: The freezer of the newly purchased refrigerator is frozen
The solution: because it is The refrigerator is new, so make sure the lower refrigerator door is open before troubleshooting. If the refrigerator door is not closed properly, the refrigerator compartment will freeze. Next, you only need to treat the ice in the freezer compartment of the refrigerator and close the door. If it is not the freezing problem caused by not closing the door properly, you can check the temperature setting of the refrigerator based on the phenomenon. If it is not these two problems, you can contact the after-sales service for processing.
Phenomena 4: What is the reason why the back wall of the refrigerator freezer freezes?
Solution: The reason for this phenomenon is that the internal evaporator pipe is connected with The distance between the inner pots is too close to cause the foam to be soaked. This results in the formation of ice when the condensed gas diffuses into the liner. This will only require removing the foam by opening the back panel of the refrigerator. Let it foam again.
Phenomena 5: The freezer compartment of the direct-cooling refrigerator freezes heavily
Solution: For direct-cooling refrigerators, ice particles are prone to appear on the back of the freezer compartment . Direct cooling refrigerators are also known as frosted or slightly frosted refrigerators. The cooling capacity of the refrigerator compartment of this type of refrigerator is obtained through the exchange of the evaporator on the back, so there is slight frost or cold particles on the back when the compressor is running. This is not much of a problem, when the temperature reaches the set temperature or the water is drained from the drain hole, the ice particles will melt away. For this type of refrigerator, care should be taken to keep the items to be frozen at least 2cm away from the back evaporator, so as to avoid the food being frozen and the back of the refrigerator being severely frozen.
Three. Methods to prevent freezing in the refrigerator compartment
1. Avoid placing foods rich in water content in the refrigerator compartment: such as soups, etc. food.
2. Know the usage of your refrigerator. Many users have certain misunderstandings about the adjustment of the refrigerated room temperature controller. Here’s a warm reminder: At present, most of the refrigerators and refrigerators have the opposite temperature. That is, the lower the temperature, the higher the number.
3. Avoid opening the refrigerator door repeatedly. The large temperature difference caused by opening the refrigerator multiple times is also the cause of freezing in the refrigerator compartment.
4. Don’t pile too much food in the refrigerator. It is often found that a layer of ice on the back of the refrigerator compartment is caused by too many food piles. When placing food, pay attention to a certain distance from the back of the refrigerator compartment.
5. When using a refrigerator, it is necessary to defrost frequently. It is also a measure to save electricity.
6. Adjust the water funnel to the position of the water tray.
7. The temperature in the refrigerator compartment should not be adjusted below 0°C, usually 2-6°C, so as to prevent the water from freezing.
8. When refrigerating beverages, handle them with care. Plastic containers with bottle caps should be placed upright on the food shelf. If placed on the food shelf, the bottle cap should be tightened tightly. , to prevent the liquid from flowing out.
9. When using the refrigerator, it is an important task to open and close the door well. Care must be taken to prevent cold running; if the sealing strip is damaged, it must be repaired in time; and it is required to pay attention to the door at any time. Check whether there is any dirt on the edge and tape, if found, wipe it off immediately.
10. Hot food is not allowed to be put in the refrigerator. Wait for it to cool down to room temperature naturally before putting it in the refrigerator.
11. For food with a lot of water content, it should be packed in plastic bags, and the bag mouth should be fastened to prevent the moisture in the food from evaporating and increase the amount of water in the refrigerator.
12. The temperature of the refrigerator compartment in the refrigerator should not be lower than 0°C, and should be controlled at 2-6°C. At this time, the bottled beverage will not burst.
13. In summer, put some water in the water container outside the refrigerator, then connect a rubber tube to the head of the water outlet pipe in the refrigerator, and connect the other end of the rubber tube. Submerged in water, this will prevent the outside hot air from entering the refrigerator to condense and drip.
14. When freezing ice cubes or popsicles, it is not advisable to add too much water in the ice maker. Generally, it is better to add 80% of the capacity.
Four. Causes and solutions of other refrigerator failures
1. Mist condensation appears on the outer surface of the refrigerator
p>
This phenomenon occurs when the air humidity is high, just wipe it dry.
2. Frost or ice beads on the back of the refrigerator compartment
Because the temperature of the back of the refrigerator compartment is lower than 0 when working in the refrigerator compartment It is normal for frost or ice beads to form, and they will automatically melt when the refrigerator is shut down.
3. Heat around the freezer door frame
This is a kind of method adopted to prevent condensation on the side of the freezer door when the air humidity is high special measures.
4. The left and right side panels of the refrigerator heat up
The refrigerator condensing radiator is close to the inside of the left and right side panels. When the refrigerator is working, the condensing radiator is used to dissipate heat. . This is the same reason that the outdoor unit needs to dissipate heat when the household air conditioner cools in summer. When the ambient temperature is high in summer, the temperature of the side panel of the refrigerator can reach about 50 degrees Celsius.
5. The compressor is hot
When the refrigerator is working, the temperature of the compressor shell can reach about 80 degrees Celsius.
6. There is a “hissing” sound of running water in the refrigerator
This is the sound of refrigerant flowing in the refrigeration pipeline when the refrigeration system is working.
