How to Fix / Troubleshooting
Safety first: Disconnect power before touching the control board or wiring.
Steps:
- 1. Power cycle: Unplug the refrigerator for 10 minutes to reset the control. Plug back in and observe if the error returns.
- 2. Inspect main control board: Remove the rear access cover and open the control board housing. Look for burnt components, bulging capacitors, or scorch marks.
- 3. Check connectors: Ensure all harnesses are fully seated and that ground connections are tight.
- 4. Surge protection: If the error followed a power outage or surge, the board is likely damaged.
- 5. Replace main control board: Install a new OEM main control board programmed for your Kenmore model. Transfer any jumpers or configuration plugs as instructed.
- 6. If unsure: Because this error often indicates board-level failure, professional diagnosis is recommended.
