Freezer interior light does not turn on when door is opened, but unit cools normally.

Safety: Unplug the freezer before replacing bulbs or working on wiring.

Steps:

• Check bulb/module: On models with replaceable bulbs, remove and visually inspect the bulb. Replace with the correct type if filament is broken or LED is dark.
• Test door switch: Press the door switch by hand; if the light flickers or never comes on, test the switch for continuity with a multimeter. Replace if faulty.
• Inspect wiring: Ensure the light assembly connector is secure and wires are intact.
• Control board: If the bulb and switch are good but no voltage is present at the light socket, the control board's light circuit may be defective and require replacement.
