Freezer: Not running

If the freezer isn’t running even though the freezer still has electrical power—check whether the inside light turns on—possible causes include a control failure, a wiring problem or a failed compressor. See the repair guides below for instructions for replacing components that could be at fault. If the freezer doesn’t have power, check the electrical outlet. Plug a night light or small appliance into the outlet to check for power. If the outlet isn’t working, reset the circuit breaker. If the outlet doesn’t work after resetting the circuit breaker, call an electrician to fix the electrical outlet.

These repairs may help solve your Freezer problem:

Replace the freezer electronic control board

Electronic control board

The electronic control board—also called the main control board or the power control board (PCB)—manages the compressor and the defrost cycle. The control board activates the compressor to keep the freezer cold and runs the fans. The electronic control board monitors temperature sensors to control freezer temperature and the defrost cycle. Replace the electronic control board if it’s not working properly.

Replace the freezer start relay and overload

Compressor start relay

The compressor start relay starts the compressor and keeps it running until the compressor cycles off. Replace the start relay if it’s broken and the compressor doesn’t run. In some situations, a wiring failure could be causing the problem, and repairing the start relay wiring will fix the problem.

Replace the freezer cold control thermostat

Temperature control thermostat

The cold control thermostat, located in the control housing, regulates the freezer temperature by cycling the compressor on and off. The sensor bulb on the cold control thermostat monitors freezer temperature. Replace the cold control thermostat if it doesn't cycle the compressor properly to maintain freezer temperature.

Replace the freezer control panel

Control panel

The control panel houses the selection buttons and the display for the freezer. The control panel communicates with the electronic control board through a wire cable. Check the wire cable connections before replacing the control panel. Replace the control panel when keys are stuck or the display doesn't work.

Replace the freezer defrost timer

Defrost timer

The defrost timer controls the intervals between defrost cycles and limits the length of the cycle. During the defrost session, the timer activates the defrost heating element and prevents the compressor from running, so frost melts from the evaporator fins. Replace the defrost timer if it doesn’t control the defrost heater and compressor properly.

Replace the freezer compressor

 Compressor

The compressor is a pump that an electric motor rotates. The compressor is the problem if the motor won’t start when the start relay actives it, or if the motor runs but the pump doesn't compress the refrigerant. Have a service technician replace the compressor, because this repair requires access to the sealed refrigerant system.
