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

Safety first: Unplug the freezer before working on the door switch or light circuit.

• Check light status: Press the door switch manually with the door open. The light should turn off. If it stays on, the switch or control is faulty.
• Inspect switch alignment: Ensure the door contacts the switch plunger fully when closed. Adjust the switch position if possible.
• Test switch: Remove the switch and test continuity with a multimeter. Replace if it does not change state when pressed.
• Control issue: If a new switch does not fix the problem, the main control board may be stuck powering the light circuit.

A light that stays on can significantly warm the cabinet; correct this issue promptly to protect food.
