How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool fully before inspection.
User checks:

- Cleaning: Remove grease and dust from vents and interior surfaces.
Advanced:
- Inspect thermal devices: Access the heater area and test thermal fuses/thermostats for intermittent operation (may require heating with a heat gun while monitoring continuity).
