Smoker trips the household breaker or GFCI when turned on

Safety first: Do not repeatedly reset a tripping breaker. Unplug the smoker and keep it disconnected until the fault is found.

Inspection steps:

• Check for moisture: If the smoker was left in rain or washed aggressively, allow it to dry for 24–48 hours in a warm, dry area before retesting.
• Inspect power cord: Look for cuts or crushed areas. Replace the cord if any copper is exposed or insulation is compromised.
• Element check: Remove the element leads and test resistance from each terminal to the metal cabinet. Any continuity indicates a ground fault; replace the element.
• Wiring inspection: Open the control box and examine all wires for melted insulation or contact with sharp metal edges. Repair or replace damaged wires and secure with high-temp wire ties.
• Test on non-GFCI (if code-allowed): Some minor leakage can trip sensitive GFCIs. However, persistent tripping usually indicates a real fault that must be corrected.

Warning: If you are not comfortable testing for ground faults, have a qualified electrician or appliance technician perform the diagnosis.
