Refrigerator Condenser Fan Motor Troubleshooting

Observe the operation of your refrigerator to hone in on the nature of the problem. If the unit turns on and off intermittently, and/or you hear a grating sound coming from the rear of the refrigerator, it is likely an issue with the fan.

Unplug your refrigerator and use a Phillips screwdriver to remove the rear panel. Identify the football-sized compressor inside. Next to it is the centrifugal fan.

Check the mounting bolts to make sure the fan and motor assembly are mounted securely. If they aren't, it could be the reason the unit isn't functioning properly. Tighten any loose bolts with a wrench.

Inspect the wiring running from the fan motor to the compressor. Check to see if the wiring is frayed or damaged. Inspect the terminals where the wiring connects to see if they are corroded. If the problem lies with the wiring, you probably need to replace the fan assembly.

Unplug the wiring from the compressor and remove the bolts holding the fan assembly to the unit.

Remove the fan assembly and fit a new one in its place. Secure the bolts and attach the wiring.

Replace the rear panel of the refrigerator.
