Possible Causes
Burned-out heating element, Loose heater terminal connection, Open thermal cutoff in series with heater, Broken heater wiring harness
How to Fix / Troubleshooting
Safety first: Unplug the air fryer and allow it to cool completely.
- Check for visible heater damage: Remove basket and pan. Inspect the heating element for breaks, blisters, or burn marks.
- Listen for relay click: Start a cycle and listen for a click from inside (heater relay). If you hear a click but no heat and E3 appears, the heater circuit is likely open.
- Do not bypass safety devices: Never bridge the thermal fuse or thermostat to "test"; this is dangerous.
- Service required: The heating element or thermal cutoff will need to be tested with a multimeter and replaced if open.
Warning: Heater replacement involves high-voltage components. If unsure, contact a professional.
