Why does the refrigerator lose heat and is not cold enough?

The situation of the refrigerator suddenly fell into a state of not being cold enough, losing heat was not uncommon. This will cause the refrigerator to have insufficient heat to ensure the amount of food stored in the cabinet, causing degradation. Besides, the lack of heat will cause the cabinet to operate at a heavier capacity, causing damage and increasing monthly electricity bills in the family. Therefore, it is necessary to find out the causes and quick fixes, to avoid prolonged heat loss that affects refrigerators and food.

1. Failure to close the refrigerator does not fit, the rubber edge is exposed:

After a process of use, many refrigerators encountered a situation of being unable to close the door due to the broken, torn rubber door (gasket) in the cabinet door. This makes the cabinet door not fit or will tend to open itself, if the user does not pay attention or leave a lot of food in the closet. These are all easy to get cold air out, making the refrigerator not cooled.

If you have a refrigerator that suddenly loses heat and reduces cooling capacity, check the rubber gasket and call a replacement if necessary. In addition, during use, users should also pay attention not to open the cabinet for a long time and close the cabinet after use.

2. Refrigerator without gas:

Just like the air conditioner without gas will not blow cold air, the refrigerator when lack of gas does not guarantee enough cold. If the gas is not enough, the refrigerator cannot be cooled, you should call a pump to add gas, the refrigerator will work better.

3. Leave the refrigerator in the wrong mode:

Normally when buying a new refrigerator, all modes are pre-installed. But by accident or for some purpose we adjust the regime. Many cases of refrigerators are not cold because the cabinets are being set to low cooling levels, or being installed in power saving mode. It should be checked whether the cabinet is being set to a low cooling level or running in power saving mode.

4. Preserving too much food in the refrigerator:

This error is very much a family or have. Refrigerators also need space for gas exchange. If you put too much food in the refrigerator, there will not be enough room for cold air to circulate, it cannot cool food.

Place a moderate amount of food and create spaces for cooling to be circulated and better.

5. Fault in refrigerator discharge unit:

The defrosting unit of the refrigerator does not work, causing the snow to freeze around the evaporating device, causing "paralysis" of the refrigeration unit's operation, leading to the refrigerator being unable to cool. The reason is that this part may be damaged during use, even due to poor sanitation.

Therefore, it is necessary to repair and replace if this part unfortunately fails. You should also remember to clean the refrigerator regularly so that the device works better.

6. Adjust the temperature inappropriately:

The cabinet usually consists of 2 compartments, the freezer with negative temperature also prevents cold with positive temperature. If placed at No. 1 (least cold) in winter, the temperature in the freezer reaches -18 degrees Celsius, the freezing temperature is about 2 - 5 degrees Celsius, and the temperature of the fruit compartment will reach 7-10 degrees Celsius. But in the summer, if you want to maintain that temperature, you need to adjust the temperature relay to 4 or 5. Because when the outside temperature rises, the temperature in the cabinet also increases.

The temperature adjustment also depends on the amount of food contained inside. If there is a lot of food stored, adjust the temperature to a higher level so that the refrigerator provides a bit cooler, avoiding food spoilage.

7. Error of humidifier:

The surface of the indoor unit has snow and then dissolves, the tube and the outdoor unit are hot, cold and short-cycle. If you observe that the refrigerator has this phenomenon, it is most likely due to the humidifier. Should call a worker to exhaust gas, dehumidify, replace the dryer, vacuum, refuel.

8. Non-enclosed cabinets, insulated with moisture or perforation:

The refrigerator has more snow on the evaporator than usual, the cabinet is less broken. The temperature in the cabinet increases, touches the cabinet near the door, it is cold or there is a dew in the back of the cabinet at the window to protect the indoor unit.

The reason is that the cabinet door is not closed, the back door cover of the indoor unit is installed with no tight wire, moisture is insulated and water is injected. Therefore, it is necessary to adjust the gap of the cabinet door reasonably by latching on the hinge, checking the magnet again, reshaping the door, relocating the cabinet to equal, balanced.

Seal the rear cover of the indoor unit and the wire conductor hole, the sensor relay thermal tube. Sealing and sealing the cabinet is not wet or lack of insulation.
