1. What is the reason for the small freezer not cooling
1. There may be a problem with the power plug or socket
First of all Check that the electrical outlet has power. If there is no power, replace the outlet or repair the outlet circuit to ensure proper power and the freezer will function properly.
2. Whether there is a cooling sound
You can listen to the humming sound of the small freezer. If there is no sound, the compressor is not working, check for compressor problems.
Solution: call the merchant to explain the cause of the failure, and ask professional maintenance personnel to repair it.
3. Compressor Problems
When the compressor does not stop day and night, the freezer compartment may cause the extreme cooling temperature of the refrigerant. The cause of ice blockage in the freezer.
Solution: unplug the power supply, after the ice in the freezer has melted slightly, control the temperature of the freezer at about 0 degrees.
4. Exhaust fan problem
It may be that the air cooling fan is broken, there is too much food in the freezer, and the air outlet is blocked, resulting in poor cooling effect.
Solution: Store food away from the vent. Therefore, when storing food in the freezer, pay attention to the placement and do not store too much food.
5. Opening times
In fact, the temperature of the freezer is related to the number of openings, especially for families with a large population or children. The more times the freezer is opened, especially when you forget to close the door, the corresponding heat will dissipate a lot, so the cooling effect of the freezer will be poor.
Solution: If you want to lower the temperature, you can only lower the temperature, or minimize the time to open the door.
6. Freon leakage
Freon in the freezer may leak. If you find a freon leak, you need to find a professional maintenance person to solve it. Pay attention to sealing before filling, do not repair it privately, so as not to cause harm to the body.
2. Reasons and solutions for frequent starts and stops of the compressor of the small freezer
Under normal working conditions, the number of times of starting and stopping of the compressor of the small freezer per hour is not It should be more than 6 times, otherwise it will be regarded as a failure. The main reasons that cause the compressor to start and stop too frequently are:
1. The power supply voltage is too high or too low, and it is unstable
Remedy : After the power supply voltage returns to normal, turn on the power supply or install an AC voltage stabilizer to provide a stable 220V power supply for the small freezer.
2. The temperature difference adjustment range of the thermostat is too small
Remedy: adjust the temperature difference adjustment screw of the thermostat, and adjust the temperature difference of the small freezer. Set in the range of 2 ~ 3 ℃. The adjustment method is to turn the temperature difference adjustment screw counterclockwise.
3. The thermostat knob is close to the stopping point, and there is too much food in the box
Remedy: turn the thermostat knob to the appropriate the middle position, and adjust the storage amount of food appropriately.
4. The disc bimetal of the over-current and over-temperature rise protection relay fails
Remedy: replace the over-current and over-temperature rise protection relay with a new one .
5. Poor heat dissipation of the condenser
The poor heat dissipation effect of the condenser will reduce the cooling capacity of the compressor, causing the compressor to run overloaded, resulting in The working current increases, causing the overcurrent protection relay to act to cut off the power supply and stop the compressor. When the protection relay bimetal feels that the temperature drops to the reset temperature, the contact is closed again, and the compressor starts to run again, causing the compressor to start and stop frequently. The main reasons for the poor cooling effect of the condenser are: there is dirt on the surface of the condenser; the ambient temperature of the freezer is too high.
Exclusion method: regularly clean the dirt of the condenser; improve the cooling conditions of the freezer.
6. The door of the freezer is not tightly sealed, and the cold leakage is serious
Remedy: repair and adjust the door seal or replace the door seal.
