Unit trips the household circuit breaker or RCD when plugged in or when heating starts.

Safety first: Do not repeatedly reset the breaker. Unplug the air fryer immediately. Risk of electric shock or fire.

• Inspect power cord: Check for cuts, crushed sections, or exposed conductors. Replace the cord set if damaged.
• Check for moisture: If the unit was recently cleaned or exposed to steam, allow it to dry in a warm, dry place for 24 hours before retesting.
• Heater insulation test: With the unit unplugged and heater disconnected, measure resistance between each heater terminal and the metal chassis. Any low resistance indicates a shorted element; replace the heating element assembly.
• PCB inspection: Look for burnt or carbonized areas on the main PCB. Replace the board if any damage is found.
• Professional testing: If you lack proper test equipment (e.g., insulation tester), have a qualified technician perform safety checks before using the appliance again.
