Interior light not working when door is opened, but cooler otherwise operates normally.

Safety: Unplug the appliance before replacing light modules or working on wiring.

Steps to restore lighting:

• Check door switch: Verify that the door switch operates (you may hear a click). Test continuity with a multimeter and replace if faulty.
• Inspect LED module: Remove the light cover and check for visible damage or discoloration. Replace the LED module if burnt.
• Verify wiring: Ensure the light harness is securely connected to the main PCB.
• Driver circuit: If the switch and LED are good but no voltage is present at the light connector, the LED driver on the main PCB may be defective and require board replacement.
