How to Fix / Troubleshooting

Safety first: Disconnect power and allow the air fryer to cool fully before inspection.

Inspection and test:

Remove the outer housing to access the top heating assembly and sensor wiring.
Trace the sensor wires from the cavity to the control board. Look for melted insulation, pinched wires, or areas where the harness touches the heating element or metal edges.
Separate any wires that are touching hot surfaces and repair damaged insulation with high-temperature sleeving or replace the harness if copper conductors are exposed.
Test the sensor with a multimeter. A reading near 0 Ω indicates a shorted sensor. Replace the sensor if shorted or if its body is discolored or cracked.
After replacing the sensor, reassemble the unit and test. If E2 still appears, the control board’s sensor circuit may be faulty and the main PCB should be replaced.

Note: Do not bypass or jumper the sensor; this is a critical safety component.

Air fryer stops heating and displays E2 during preheat or cooking.
