How to Fix / Troubleshooting

High-voltage safety: Unplug the refrigerator and wait several minutes before touching compressor or inverter wiring. Compressor work should generally be done by professionals.

Steps:

  • 1. Listen for compressor attempts: If the compressor clicks or hums briefly then stops, there may be a start or inverter issue.
  • 2. Inspect inverter module: Remove the rear cover and check the inverter (if separate) for burn marks or a burnt smell.
  • 3. Check wiring: Ensure all connectors to the compressor and inverter are secure and undamaged.
  • 4. Board replacement: If wiring is good and F6 persists, the inverter module or main PCB may need replacement. Compressor testing and replacement should be done by a certified technician.
