How to Fix / Troubleshooting

Safety: Do not repeatedly reset the breaker. Unplug the air fryer and keep it unplugged until the fault is found.

Check cord: Inspect the power cord for cuts or crushed sections. Replace if damaged.
Dry the unit: If the fryer was recently washed or exposed to heavy steam, allow it to dry for 48 hours in a warm, dry place.
Open housing (advanced): Inspect the heater, wiring, and PCB for signs of arcing, burn marks, or melted insulation.
Test heater to earth: With a multimeter, check resistance between each heater terminal and the metal chassis. A low resistance indicates a shorted heating element that must be replaced.
PCB inspection: Replace the control PCB if any components are visibly burnt or cracked.
Professional help: If you are not experienced with mains electrical testing, contact a qualified technician.
