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

Safety first: Do not repeatedly reset a breaker that keeps tripping. Unplug the smoker before inspection.

• Inspect cord and plug: Look for cuts, crushed sections, or burn marks. Replace the cord if damaged.
• Check for moisture: Open the control panel and look for water or condensation. Dry thoroughly and avoid using the smoker in heavy rain.
• Inspect wiring: Follow the wires from the element and control board, checking for pinched or bare conductors touching metal.
• Test element to ground: With the smoker unplugged, measure resistance between each element terminal and the metal cabinet. Any low resistance indicates a ground fault; replace the element.
