Possible Causes

How to Fix / Troubleshooting
Safety: Immediately unplug the air fryer and move it to a non-combustible surface. Do not continue using it until the cause is identified.
Steps:
- 1. Visual inspection: After cooling, inspect the interior for burnt food or grease on the heater. Clean thoroughly if present.
- 2. Check wiring: Remove the base cover and inspect all wiring near the heater and motor for melted insulation or burn marks. Replace any damaged harnesses.
- 3. Inspect PCB: Look for burnt components or darkened areas on the main control PCB. A burnt board must be replaced.
- 4. Motor check: If the smell seems to come from the fan area and is accompanied by unusual noise, the motor windings may be overheating; replace the motor.
- 5. Test cautiously: After repairs and cleaning, run the unit under supervision. If the smell persists, discontinue use and consult a technician.
Warning: Persistent burning smell is a fire hazard. Do not ignore it.
