How to Fix / Troubleshooting
Safety first: Unplug the smoker immediately if you smell burning or see smoke.
- Visual inspection: Remove access panels and inspect wiring harnesses, fan motor, and control board for burn marks or melted insulation.
- Isolate loads: Disconnect non-essential loads (such as accessory lights or auxiliary fans) one at a time and test, if you have service documentation, to identify a shorted component.
- Check harness routing: Ensure wires are not pinched between panels or contacting hot surfaces.
- Board evaluation: If no external shorts are found, the internal power supply on the main control PCB may be failing. Replacement of the board is typically required.
