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.
