Sub-Zero Refrigerator Compressor Running All the Time – What to Do
If you notice that your refrigerator compressor is running all the time, it could mean that something is wrong with your unit. This is not normal and if it continues to run all the time, it can damage your appliance. It is important to know that the compressor runs constantly because it keeps the refrigeration system working properly. In addition, the compressor helps maintain the cold air inside the refrigerator. So, if the compressor is running all the way, it means that the refrigeration system is not functioning correctly. To fix this problem, you need to check the following items:
1. Ambient Temperature
Check the ambient temperature of the refrigerator. If the temperature is low, it means that the refrigerator is not cooling well. Make sure that the thermostat is set to the correct setting. Also, check the door seals and the insulation around the doors. 2. Defrosting Answer: Check whether the defrost timer is set to the correct time. If it is set to a long period, it means that the freezer needs to be defrosted frequently. To defrost the freezer, turn off the power switch and wait until the ice melts. Then, turn the power back on and continue to defrost.
2. Refrigerator Usage
If the refrigerator is running constantly, it means that the compressor is working continuously. This could mean that the compressor is damaged. It is recommended to call a professional repair service to fix the problem. 3. Humidity Control Answer: Check the humidity level in the refrigerator. If the humidity level is high, it means that the air conditioner is not functioning properly. In order to reduce the humidity level, open the windows and let the air circulate freely.
3. Food Storage
Store food items in the refrigerator in such a way that they remain cool. For instance, if you store fruits and vegetables in the refrigerator, place them on the bottom shelf where cold air circulates around them. 4. Water Temperature Answer: Make sure that the water temperature in the refrigerator is set to 40 degrees Fahrenheit.
4. Leaky Gasket
To prevent leaking gaskets, tighten the screws after each use. 5. Cleaning the Refrigerator Answer: To clean the refrigerator, remove the shelves and wipe down the interior walls with a damp cloth.
5. Dirty Coils
Clean coils by removing the fan assembly from the back of the unit. Remove the dust filter from the front of the unit. Using compressed air, blow out any remaining dust particles. Replace the dust filter and reassemble the unit. 6. Dusty Filter Answer: Use compressed air to blow out any remaining dust from the filter.
6. Defrost System
Defrosting is done using a heating element located within the base of the unit. This element heats the interior of the unit until the ice melts. Once melted, the ice falls into a bin located below the unit. 7. Fan Assembly Answer: Remove the fan assembly from the rear of the unit.

1. Operation of Condenser Fan
2. Check the condenser fan motor for loose connections or worn brushes. 3. Check the condenser coils for cracks or corrosion.
2. Faulty Component
1. Operation of Condenser fan Condensers are used to remove moisture from air passing through the evaporator coil. This is done by forcing hot air across the surface of the coil where it picks up moisture from the air. The moist air passes through the condenser where it cools down and releases the moisture back into the atmosphere. A condenser fan is connected to the condenser to force air past the coil and thus remove the moisture. The condenser fan consists of two parts; a motor and a blower wheel. The motor is attached to the blower wheel which is mounted on the condenser. The blower wheel is driven by the motor. The motor turns the blower wheel which forces air past the condenser coil. In order to ensure proper operation of the condenser fan, the following conditions must be met: a The motor must be running.
