Unit trips the household circuit breaker or RCD when turned on.

Safety first: Do not repeatedly reset the breaker. Unplug the air fryer and leave it unplugged until the fault is found. Risk of electric shock and fire is present.

Steps:

• 1. Visual inspection: Check the power cord for cuts or crushed areas. Replace if damaged.
• 2. Dry the unit: If the fryer was recently cleaned with excessive water or used in a very humid environment, allow it to dry for 24 hours in a warm, dry place.
• 3. Inspect internal wiring: Remove the cover and look for wires touching sharp metal edges, burn marks, or melted insulation.
• 4. Check heater to ground: With the unit unplugged, measure resistance between each heater terminal and the metal chassis. A low resistance indicates a shorted element that must be replaced.
• 5. Examine PCB: Look for obvious shorts such as solder bridges or burnt components. Replace the PCB if damaged.

Warning: If you are not experienced with electrical testing, have a qualified technician diagnose ground faults.
