Chosen Solution
We have an upright Frigidaire Freezer (model LFFH17F7HWH) that keeps running. It freezes nicely. We have ran through everything we were told and replaced the control panel, door gasket, thermostat control and defrost heater, the thermistor, the run capacitor and the control compressor regulator. Still running. Temp shows 17-25 (fluctuates when we open the door) on control panel yet inside is nice and cold and everything is frozen like it should be.
Cause 1 Evaporator Fan Motor The evaporator fan motor draws air over the evaporator coils and circulates it throughout the freezer. On most refrigerators, the fan motor will not run when the door is open. Make sure that the refrigerator door is closed and the door switch is activated. If the door switch is activated but the evaporator fan motor still won’t run, replace the evaporator fan motor. Parts Evaporator Fan Motor for your Frigidaire Freezer RepairClinic Item #1483843 Evaporator (cooling coil) fan motor assembly with wire harness, 115 volts. *Per manufacturer screw holes in motor are not threaded from the factory, use old screws. See Related Items for self tapping screw. When the evaporator fan motor fails, it often generates a lot of noise in the freezer area. Cause 2 Condenser Coils are Dirty If the condenser coils are located within the freezer walls, the coils do not require cleaning. However, if the condenser coils can be readily accessed from behind or under the unit, you should clean them every 6-12 months. If the condenser coils are dirty, they won’t be able to dissipate heat effectively, greatly reducing the cooling capacity of the freezer. If the condenser coils are dirty or have not been cleaned in a while, clean them. Cause 4 Sealed System Leak If the freezer only freezes the top shelf, there may be a sealed system leak in one of the shelves. Sealed system repairs are usually cost-prohibitive. If the sealed system is leaking, you will probably need to replace the freezer.
