Smoker trips the household breaker or GFCI outlet when turned on or when heating starts.

Safety first: Unplug the smoker immediately. Do not repeatedly reset a tripping breaker without finding the cause.

• Inspect power cord: Look for cuts or crushed areas where copper may be exposed. Replace the cord if any damage is found.
• Check for moisture: Open the control housing and look for water or condensation. Dry thoroughly and allow time for complete evaporation before retesting.
• Inspect heating element: Look for spots where the element touches the metal cabinet or shows burn-through. A shorted element must be replaced.
• Check internal wiring: Follow the wiring harness and ensure no wires are pinched under panels or rubbing against sharp metal edges. Repair or replace damaged wires.
• Test on non-GFCI outlet: After repairs, test on a standard outlet (if safe and code-compliant) to confirm the issue is resolved. If tripping continues, consult a qualified technician.
