How to Fix / Troubleshooting

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

Steps:

  • 1. Visual inspection: After unplugging and allowing components to cool, remove the rear cover and inspect the main control board, compressor area, and wiring for burn marks or melted insulation.
  • 2. Check control panel: Remove the front control panel cover and inspect the user interface board for signs of overheating.
  • 3. Identify damaged parts: Any visibly burnt PCB, connector, or wire must be replaced. Do not attempt to repair burnt boards at component level unless qualified.
  • 4. Replace affected assemblies: Install a new main control board, fan motor, or wiring harness as required.

Warning: Because of fire risk, if you are unsure of the source of the smell, have the refrigerator inspected by a professional before using it again.
