Unit trips the household circuit breaker or GFCI when starting or during cooking.

Safety first: Repeated breaker trips indicate a potentially dangerous fault. Unplug the unit and do not continue using it until repaired.

• Try another outlet: Plug into a different properly grounded outlet on a different circuit to rule out a weak breaker (do not bypass GFCI protection in wet areas).
• Inspect cord: Check the power cord for cuts or crushed sections. Replace if damaged.
• Internal inspection: Remove the cover and look for wires with damaged insulation touching the metal chassis, especially near the heater and fan.
• Element test: Use a multimeter to check resistance between each heater terminal and the metal chassis. Any continuity indicates a shorted element that must be replaced.
• Dry moisture: If there are signs of moisture on the control board, allow it to dry completely or replace the board if corrosion is present.
