What is the model number of your refrigerator or is it a freezer?

Can you hear the evaporator fan running? (it is inside the freezer compartment behind a panel. It stops when a door is opened and starts again when the door is shut). Do not confuse it with the condenser fan which is outside both the fridge compartments

The evaporator fan should be running as long as the compressor motor is running. This drives down the temp in the freezer and the refrigerator to the correct temps.

If the fan is not running then it may be iced up due to either a faulty defrost heater, thermostat or perhaps the fan itself may be faulty.



My LG ref model no. GR-B207GSQV, a side by side door type, the chiller temperature has changed but still cooling some water bottles in it. The freezer wont freeze but still cold. The evaporator fan inside the freezer compartment is running. What to do to apply the process of elimination as there maybe couple of faulty parts not working properly.

Chosen Solution

These are the most common things to check first. Let me know if one of these does not do the trick:

Cause 1

Condenser Coils are Dirty

The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won’t dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils to determine if they are dirty—if the condenser coils are dirty, clean them.

Cause 2

Condenser Fan Motor

The condenser fan motor draws air though the condenser coils and over the compressor. If the condenser fan motor is not working properly, the refrigerator won’t cool properly. To determine if the fan motor is defective, first check the fan blade for obstructions. Next, try turning the fan motor blade by hand. If the blade does not spin freely, replace the condenser fan motor. If no obstructions are present and the fan blade spins freely, use a multimeter to test the fan motor for continuity. If the condenser fan motor does not have continuity, replace it.

Cause 3

Evaporator Fan Motor

The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.
