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

Safety first: Unplug the unit and do not repeatedly reset a tripping breaker; this indicates a potentially dangerous fault.

• Check other loads: Ensure the air fryer is on a dedicated circuit or not sharing with other high-wattage appliances.
• Inspect cord and plug: Look for cuts, burns, or loose prongs on the power cord. Replace if damaged.
• Internal inspection: Remove the cover and look for signs of arcing, burned spots, or moisture on the main control board, heater terminals, and wiring.
• Element to ground test: With the unit unplugged, measure resistance between each heater terminal and the metal chassis. A low resistance indicates a ground fault and the heating element assembly should be replaced.
• Dry moisture: If there are signs of liquid ingress, allow the unit to dry thoroughly for 24–48 hours before retesting.

If the breaker still trips after visible faults are corrected, have a qualified technician perform further insulation and leakage tests.
