Interior light not working, but cooler otherwise operates normally.

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

Steps:

• Check light switch: Verify that the door switch operates the light (press it manually). Replace the switch if it does not change the light state.
• Inspect LED module: Remove the light cover and check the LED light strip or module for discoloration or burn marks.
• Check connections: Ensure the light harness is firmly connected to the control board.
• Replace LED assembly: If the switch and wiring are good, replace the LED light module with a compatible Costway part.
