How to Fix / Troubleshooting
Safety first: Unplug the smoker before opening any panels.
- Check outlet and polarity: Use a receptacle tester to verify correct wiring and ground at the outlet. Avoid using long, undersized extension cords.
- Inspect main harness: Remove the control panel and verify the main wiring harness plug is fully seated on the control board.
- Look for moisture: Check inside the control housing for condensation or water intrusion. Dry thoroughly and allow several hours before retesting.
- Perform hard reset: Leave the smoker unplugged for 10–15 minutes, then plug back in and see if the error clears.
- Replace control board: If the generic error persists and all connections and power are correct, replace the main control board.
