How to fix it
- Unplug refrigerator for 5 minutes and restore power.
- Listen for compressor start attempt — clicking with no run indicates inverter or compressor fault.
- Unplug and remove the rear compressor cover.
- Inspect the inverter (small board on side of compressor) for burn marks; reseat its connector.
- Measure outlet voltage during start attempt.
- Replace the inverter board first — usually solves the issue.
- If new inverter still throws F9E1, the compressor itself has failed and needs a sealed-system tech.
