Customer Questions and Answers for Refrigerator Led Light Module Kit by Whirlpool

Tim, the LED control W11368839 would need to be tested at the two-wire connection for 120VAC when the doors are open. If there is voltage, the wires at pin one to pin two, pin three to pin four, and pin five to pin six would need to be tested for 12VDC. If there is not DC voltage, the LED control has failed. If there was not voltage going to the LED control, the door switches would need to be tested to identify if one has failed or if there is a wire failure in the liner. The door switches can be tested for continuity when the refrigerator power supply is off. There should be continuity when the switches are not being depressed.
