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

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

Steps:

• Check if light is on: Look through door gaps or listen for the light relay click when pressing the switch manually.
• Inspect the switch: Press the door switch plunger by hand. If the light does not turn off or the plunger sticks, replace the switch.
• Verify door closure: Ensure the door gasket is not hitting shelves or food, preventing full closure.
• Replace the switch: Remove the old switch from the liner, transfer wires to the new switch, and snap or screw it back in place.

Tip: A light that stays on can significantly warm the upper section and cause partial thawing; fix promptly.
