Interior light stays on when door is closed, causing warmth near light area.

Safety first: Unplug the refrigerator before removing the light cover or switch.

Check door switch:

• Press the door switch manually; the light should turn on and off (when powered).
• If the switch feels stuck or loose, remove it from the liner and inspect wiring.

Door alignment:

• Ensure the door closes fully and contacts the switch plunger.
• Adjust leveling legs or hinges if necessary.

Repair: Replace a faulty door switch or incorrect bulb with the proper Summit-specified part. If the light remains on even with the switch disconnected, the main control board light relay may be stuck and require replacement.
