How to Fix / Troubleshooting
Safety first: Unplug the unit before inspection.
- Check cord and outlet: Ensure the plug is secure and not wiggling in the outlet. Avoid using loose power strips.
- Ventilation: Make sure the air fryer has adequate clearance and is not enclosed in a cabinet during use.
- Inspect control board: Remove the housing and look for signs of overheating on the PCB (darkened areas, warped plastic). Ensure the board is not directly blocked from airflow.
- Check thermal devices: Test the high-limit thermostat and thermal fuse for intermittent behavior by gently tapping while measuring continuity. Replace any suspect components.
If shutdowns continue, the main control PCB may be failing under heat and should be replaced.
