AEG air fryer trips the household circuit breaker or RCD when plugged in or when heating starts.

Safety first: Do not repeatedly reset the breaker. Unplug the appliance immediately. Work only when the unit is disconnected from mains.

Steps to investigate:

• Visual inspection: Check the power cord for cuts or crushed sections. Replace the power cord if damaged.
• Check for moisture: If the unit was recently washed or exposed to steam, allow it to dry for 24–48 hours in a warm, dry place before retesting.
• Inspect heater: Access the heating element and look for signs of arcing or contact with the metal chassis. Test resistance from each heater terminal to chassis ground; any low resistance indicates a shorted element that must be replaced.
• Examine PCB: Inspect the main control board for burnt tracks, exploded components, or carbonized areas. Replace the main control board if damage is found.
• Professional testing: If you cannot locate the fault visually, have a technician perform insulation resistance tests to identify leakage paths.
