How to Fix / Troubleshooting
Safety first: Always unplug the refrigerator before touching the control board or wiring.
Power cycle:
- Unplug the unit for at least 10 minutes to fully discharge the control board.
- Plug back in and observe if E9 reappears immediately or after some time.
Inspect the control board:
- Remove the rear access panel to expose the main board.
- Look for burnt components, bulging capacitors, or signs of moisture.
- Check that all harnesses are fully seated and not pinched.
Surge protection: If E9 appeared after a storm or outage, consider using a surge protector once the board is repaired or replaced.
Important: Board-level repair and firmware issues generally require a professional technician. Do not attempt to modify or reprogram the board yourself.
