How to Fix / Troubleshooting
Safety first: Unplug the air fryer. High voltages and stored energy may be present on the main board.
User-level steps:
- Power-cycle: Unplug for 10 minutes to allow capacitors to discharge, then reconnect and test.
- Avoid overloading: Ensure you are not exceeding the recommended food quantity, which can cause overcurrent conditions.
Technical inspection (for qualified technicians):
- Inspect the main control board for burnt MOSFETs or resistors in the heater drive circuit.
- Check solder joints on high-current paths to the heater.
Corrective actions:
- Replace the main control board if any power components are damaged or if P2 persists after basic resets.
