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

Safety: Unplug the cooler before working on the light assembly.

Steps:

• Check door switch: Some Arctic King models use a mechanical switch; others use a magnetic reed switch. Locate the switch near the door frame and press it manually to see if the light responds.
• Inspect LED module: Remove the light cover inside the cabinet. Check for burnt or discolored LEDs.
• Test voltage (advanced): With the unit plugged in and door open, carefully test for low-voltage power at the light connector (only if you are qualified). If voltage is present but the light is off, replace the LED light module.
• Check wiring: Ensure the harness from the control board to the light is intact and firmly connected.

Note: A failed light does not affect cooling but should be repaired for convenience and to avoid working in a dark cabinet.
