Oster air fryer trips the household circuit breaker or GFCI outlet when turned on.

Safety: Repeated breaker tripping indicates a potentially dangerous fault. Unplug the fryer and do not continue resetting the breaker without inspection.

• Try another outlet: Plug the fryer into a different non-GFCI outlet on a separate circuit to confirm the issue follows the appliance.
• Inspect cord: Check the power cord for cuts, crushed sections, or exposed conductors. Replace if damaged.
• Dry the unit: If the fryer was recently washed or exposed to heavy steam, allow it to dry for 24 hours in a warm, dry place.
• Internal inspection (advanced): Remove the housing and inspect wiring around the heater and fan for bare wires touching the metal chassis. Look for burn marks or carbon tracking.
• Test heater to ground: With a multimeter, check resistance between each heater terminal and the metal chassis. Any low resistance indicates a shorted element that must be replaced.
• Repair wiring: Replace any damaged wires and secure them with proper routing and clamps to prevent pinching.
