Freezer interior light does not turn on when door is opened.

Safety: Unplug the freezer before replacing bulbs or switches.

Steps:

• Check bulb: Remove the light cover and inspect the bulb or LED module. Replace a burned-out bulb with the correct type and wattage.
• Door switch test: Press the door switch manually; if the light does not respond, test the switch for continuity and replace the door switch if faulty.
• Inspect wiring: Ensure connectors to the light and switch are secure.
• Control board: If bulb and switch are good but no power reaches the light, the main control board may have a failed light circuit.
