Possible Causes

Shorted heating element to chassis, Damaged power cord, Moisture in electrical compartment, Overloaded circuit shared with other appliances

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker; this indicates a potentially dangerous fault.

  • Isolate the circuit: Plug the smoker into a dedicated outlet with no other high-load devices. If the breaker still trips, the issue is within the smoker.
  • Inspect cord and plug: Look for cuts, crushed sections, or burn marks. Replace the cord if damaged.
  • Check for moisture: Open the control compartment and look for condensation or water. Allow to dry thoroughly before retesting.
  • Element inspection: Examine the heating element for contact with the metal cabinet. A grounded element must be replaced.
  • Professional testing: If the cause is not obvious, have a qualified technician perform insulation resistance tests before further use.
