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

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

• Check light settings: Some Monogram models allow disabling the interior light via the control panel. Confirm the light is not turned off in settings.
• Test door switch: Manually actuate the door switch (plunger or magnet) and see if the display responds. If the control recognizes door open/close but the light stays off, the issue is in the light circuit.
• Inspect LED module: Remove the light lens or trim and check the LED board for burn marks or discoloration. Replace the LED module if visibly damaged.
• Check wiring: Trace the light harness back to the control board and ensure connectors are secure.
• Control board driver: If a known-good LED module does not light and there is no voltage at the light connector (test only if qualified), the LED driver on the main control board may be faulty and require board replacement.

Use only OEM or compatible LED modules to avoid overloading the driver circuit.
