How to Fix / Troubleshooting
Safety first: Unplug and allow to cool before inspection.
- Improve ventilation: Ensure at least 10 cm clearance around the unit and that vents are not blocked.
- Clean internal components: Remove grease and dust from the heater, fan, and vents to improve cooling.
- Check power connections: Open the base and inspect the mains input, internal fuse, and PCB connectors for looseness or heat damage. Tighten or replace as needed.
- Test thermal cut‑out: If accessible, test the thermal cut‑out for proper operation. Replace if it trips at lower than rated temperatures or shows signs of fatigue.
- PCB power section: If shut‑offs persist, the power supply section of the main PCB may be overheating or failing; replace the PCB.
