Interior light does not turn on when the door is opened, but the cooler otherwise works.

Safety: Unplug the cooler before accessing the light assembly.

• Check light switch: If your Antarctic Star uses a mechanical door switch, press it manually and see if the light comes on. Replace the door switch if it fails.
• Inspect LED module: Remove the light cover inside the cabinet. Check the LED board for burn marks or loose connections.
• Test wiring: Ensure the light connector is firmly attached to the harness.
• Replace LED module: If the module is defective, install a new interior LED light assembly compatible with your model.
• Control board: If the switch and LED are good but no power reaches the light, the main control PCB light circuit may be faulty.
