How to Fix / Troubleshooting

Safety: Immediately unplug the refrigerator if you smell burning or see smoke. Do not continue to operate the appliance.

  • 1. Inspect rear components: After unplugging and allowing to cool, remove the rear cover and look for burnt wiring, melted connectors, or discolored components on the PCB.
  • 2. Check fan motors: Smell near the condenser fan and compressor area. A burnt odor from the fan motor indicates it should be replaced.
  • 3. Examine wiring harnesses: Look for melted insulation or arcing marks. Repair or replace damaged harness sections.
  • 4. Do not bypass safety devices: Never bypass thermal fuses or overloads to "get it running".
  • 5. Call a technician: Due to fire risk, have a qualified technician inspect and replace any burnt components or boards.
