Wine cooler interior light does not turn on when the door is opened, but cooling still works.

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

Steps to restore interior lighting:

• 1. Check light settings: Some Insignia models have a light on/off button. Ensure the light is not manually turned off.
• 2. Test the door switch: Press the door switch (or place a magnet near the reed sensor) with the door open and see if the light comes on. If not, suspect the switch or light module.
• 3. Inspect the LED module: Remove the light lens or cover inside the cabinet. Check for obvious damage or discoloration of the LED board.
• 4. Check wiring: Ensure the light module connector is firmly plugged in and that wires are not damaged.
• 5. Replace failed parts: If the door switch does not change state (no click or no continuity), replace the door switch. If the switch is good but the light never illuminates, replace the Insignia LED light module.

Note: LED modules are not typically repairable at component level; they are replaced as an assembly.
