Possible Causes

Dirty condenser coils, Failed condenser fan motor, Door gaskets leaking warm air, Low refrigerant charge from leak

How to Fix / Troubleshooting

Safety: Unplug the unit before cleaning or working at the rear.

  • 1. Clean condenser coils: Pull the refrigerator away from the wall. Use a brush and vacuum to remove dust from coils and fan area.
  • 2. Check condenser fan: With power restored briefly, verify the rear fan runs when the compressor is on. If not, unplug and replace the condenser fan motor.
  • 3. Inspect door gaskets: Look for gaps, tears, or hardened sections. Close a sheet of paper in the door; if it pulls out easily, the seal is weak. Replace gaskets as needed.
  • 4. Monitor performance: After cleaning and gasket checks, allow 24 hours. If the unit still runs constantly and remains warm, a sealed system issue (leak or restriction) is likely and requires a technician.
