If your Caloric refrigerator light is out, the likely causes range from a bad light assembly to simple component failures you can check yourself. Start by inspecting the light assembly and the bulb since those are the most common fixes; some models require replacing the entire light assembly rather than individual pieces. Next check the light switch, door switch and the light socket for power and continuity with a multimeter; those parts frequently fail and are straightforward to replace. Only rarely is the dispenser control board to blame, but if the dispenser light stays dark after you’ve ruled out the bulb, switches and socket, look for burned components on the board or test for voltage at the plug-in connector. Whether you need a replacement light bulb, socket, switch or a full light assembly, RepairClinic has the parts and step-by-step guidance.

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.
First, ensure that the light board is receiving the proper amount of voltage. If the light board is receiving sufficient voltage, but the refrigerator light will not work, replace the light board.
