Possible Causes

Failed condenser fan motor, Obstructed fan blades, Loose or damaged fan wiring, Faulty main control board fan output

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing the rear of the refrigerator.

Steps to check:

  • Access the condenser fan: Remove the rear lower access panel to expose the condenser coil and fan assembly.
  • Inspect for obstructions: Check for debris, insulation, or wiring interfering with the fan blades. Clear any obstructions.
  • Spin test: Gently spin the fan by hand. If it is stiff or seized, the motor is likely bad and should be replaced.
  • Electrical test: With power restored and a call for cooling active, check for voltage at the fan motor connector. If voltage is present but the fan does not run, replace the condenser fan motor.

Note: If no voltage is present at the fan when it should be running, the main control board or wiring may be at fault and should be diagnosed by a technician.
