Freezer interior light stays on even when the door is closed, causing warming near the door.

Safety first: Unplug the freezer before removing the door switch.

• Step 1 – Confirm light behavior: Press the door switch by hand. The light should turn off. If it does not, the switch or control is faulty.
• Step 2 – Inspect switch alignment: Ensure the door actually contacts the switch plunger when closed. Adjust door hinges if needed.
• Step 3 – Replace switch: Pry the switch out, disconnect wiring, install a new KitchenAid-compatible switch, and reconnect wiring.

If the light remains on with a new switch, the control board may be defective and requires professional diagnosis.
