How to Fix / Troubleshooting

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

Steps:

  • 1. Ventilation: Ensure adequate clearance around the unit and clean all vents.
  • 2. Interior cleaning: Remove grease buildup that can trap heat.
  • 3. Fan performance: Confirm the fan runs at full speed; a slow fan can cause overheating. Replace the fan motor if weak.
  • 4. Thermostat: Test the auto‑reset thermostat for proper operation; replace if it trips at too low a temperature.
  • 5. Wiring: Inspect mains connections and spade terminals for looseness that could cause intermittent power loss when hot.
