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

Safety: Unplug the unit to prevent overheating and electrical shock.

• Check door alignment: Ensure the door closes fully and contacts the switch plunger. Adjust hinges if the door is sagging.
• Test door switch: Remove and test the switch with a multimeter. Replace the door switch if it remains closed regardless of position.
• Temporary workaround: You may disconnect the light connector to prevent heating until proper parts are obtained.
• Control board: If the light remains on even with the switch disconnected, the main control board light circuit is likely shorted and must be replaced.
