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

Safety: Unplug the unit before working on the door switch or control board.

• 1. Verify door alignment: Ensure the door fully closes and contacts the switch plunger. Adjust hinges if needed.
• 2. Test door switch: Remove and test for proper open/closed continuity. Replace if it does not change state.
• 3. Inspect control board: If the switch is good but the light remains on, the control board may be stuck driving the light. Replace the main control board.
• 4. Temporary mitigation: Remove the light bulb or disconnect the LED module until repairs are completed to prevent overheating the cabinet.
