How to Fix / Troubleshooting

Safety first: Unplug and allow the unit to cool fully before inspection.

User checks:

  • Ventilation: Ensure adequate clearance around the unit and that vents are not blocked.
  • 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).
  • Check connections: Inspect and tighten all screw terminals and connectors in the power path.

Next steps: If the unit repeatedly shuts off under normal use, replace the thermal cutoff or main control board as indicated by testing.
