How to Fix / Troubleshooting

Safety: Unplug the unit before adjusting switches or controls.

Check door closure: Ensure nothing is blocking the door from closing fully (e.g., protruding bottles or shelves).
Inspect gasket and hinges: Make sure the door is aligned and the gasket contacts the frame evenly.
Test door switch: Press the switch manually (or place a magnet over the frame for magnetic types). If the light does not turn off, replace the door switch / magnetic reed switch.
Control board: If a new switch does not fix the issue, the main control PCB may be misreading the door status and require replacement.

Interior light stays on even when the door is closed, causing overheating.
