E04 appears on the display and the unit shuts down mid-cycle, often when cooking at high temperatures.

Safety first: Unplug the air fryer immediately. A suspected short circuit can present a shock or fire hazard.

• Step 1 – Check outlet and circuit: Verify that the wall outlet is not overloaded and that the circuit breaker has not tripped. Avoid using extension cords or power strips; plug directly into a grounded outlet.
• Step 2 – Inspect power cord: Look for cuts, kinks, or burn marks along the cord and at the plug. If damaged, do not use the unit until the cord is replaced by a qualified technician.
• Step 3 – Smell and visual check: After cooling, carefully smell around the vents for a burnt electronics odor. If present, internal components may be damaged.
• Step 4 – Internal inspection (advanced): With the unit unplugged, remove the cover and inspect the wiring from the power entry to the control board and heating element. Look for melted insulation, charred connectors, or arcing marks.
• Step 5 – Do not power repeatedly: Repeatedly trying to restart a unit with an overcurrent fault can worsen damage. If E04 reappears after a single reset attempt, stop using the appliance.
• Step 6 – Professional service: Overcurrent faults typically require replacement of the heating element, wiring harness, or control board. These repairs should be performed by a professional.
