Smoker trips breaker or GFCI after running for several minutes.

Safety first: Unplug the smoker and let it cool before testing.

• Use dedicated circuit: Ensure the smoker is on its own 15A or 20A circuit without other heavy loads.
• Test element hot (advanced): If possible, monitor current draw with a clamp meter while the smoker runs; excessive current suggests a failing element.
• Inspect high-limit thermostat: Look for signs of arcing or heat damage at the thermostat terminals. Replace if suspect.
• Replace heating element: If the breaker trips only after the element heats up, the element may be breaking down internally; replace with a new Smokehouse heating element.
