Interior light does not turn on when door is opened, but cooling works normally.

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

Steps to check and fix:

• 1. Check door switch: Verify that the door switch operates correctly and that other door-dependent functions (like fan stop) work. Replace the switch if faulty.
• 2. Access light assembly: Remove the light cover inside the cabinet (usually clipped or screwed). Inspect the LED module or bulb.
• 3. Test or replace light: For LED modules, replace the entire module with a Vestfrost-compatible part. For bulb-based systems, install a new bulb of the correct type and rating.
• 4. Inspect wiring: Ensure the light wiring harness is intact and firmly connected to the PCB.
• 5. PCB driver: If a known-good light and switch do not work, the light driver circuit on the main PCB may be defective and require board replacement.
