Safety: Unplug the refrigerator before working on electrical components.

Step 1 – Check light behavior: Press the door switch manually. The light should turn off. If it stays on, the switch or control is faulty.
Step 2 – Replace door switch: Remove and test the switch with a multimeter. Replace if it does not open/close properly.
Step 3 – Control board check: If the switch is good but the light remains on, the control PCB may have a stuck transistor or relay. This typically requires PCB replacement.

Interior light stays on when door is closed, compartment gets warm near light area
