If your JC Penney refrigerator light is not working or the fridge light is out, the most common causes are a failed light assembly or a burned-out bulb, so start by checking those first. If the assembly is sold only as a unit you may need to replace the whole housing, and swapping in a fresh bulb rules out the simple stuff quickly. A faulty dispenser control board can cause a dispenser light problem but is less likely; inspect the board for burn marks or use a multimeter to check for voltage at the light connector before replacing it. Also test the light switch and the door switch for continuity with a multimeter, and check the light socket for power—if the socket has power but the bulb does not light, the socket is bad.

03 - JC Penney Refrigerator Dispenser Control Board
While it's not a likely cause, a defective dispenser control board could be responsible for a dispenser light not working. You can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to determine if the board is sending voltage to the dispenser light's plug-in connecter. If no voltage is present, you'll know the board is defective and will need to be replaced.
To determine if the door switch is defective, use a multimeter to test it for continuity. If the door switch does not have continuity when activated, replace it.
To determine if the light socket is defective, use a multimeter to determine if the socket is getting power. If the socket is getting power, but the light bulb won’t work, this indicates that the light socket is defective. If the light socket is defective, replace it.
