Freezer interior light does not work, but cooling is normal.

Safety: Unplug before replacing bulbs or accessing wiring.

Steps:

• Check bulb/module: On models with replaceable bulbs, remove and inspect the bulb. Replace with the correct type if filament is broken. For LED modules, replace the entire module if visibly damaged.
• Door switch: Test the door switch for continuity as described under E9. Replace if faulty.
• Wiring: Inspect the light wiring and connectors for looseness or damage. Reseat connectors.
• Control board: If the light still does not work and all else is good, the light driver on the main PCB may have failed. Replace the board if necessary.
