E10 error code appears and the unit shuts down or will not start, often after long use.

Safety first: Immediately unplug the air fryer if you see E10, smell burning, or see smoke. Do not attempt to restart until inspected.

Steps to troubleshoot E10:

• Visual and smell check: Remove the basket and drawer. Smell for burnt plastic or wiring. Look for soot or melted areas around the heater and fan.
• Inspect wiring: Remove the bottom and/or rear cover. Carefully inspect all wiring harnesses for melted insulation, exposed copper, or contact with metal edges.
• Check heater and fan: Disconnect the heating element and fan motor one at a time and test continuity to the metal chassis. Any continuity indicates a short to ground and the part must be replaced.
• Component isolation: With a multimeter, measure resistance across the heater and fan. Extremely low resistance (near 0 Ω) suggests an internal short.
• Replace shorted parts: Replace any shorted heater, fan motor, or damaged wiring harness with genuine Pro Breeze components.
• Control board check: If all loads test normal, the control PCB may have a shorted triac, relay, or power supply component and should be replaced.

Warning: Do not continue using the air fryer if E10 recurs after part replacement. Persistent overcurrent faults are a fire and shock hazard.
