If your refrigerator light not working, start with the parts most likely to fail and work down the list: the entire light assembly can be bad (some manufacturers only sell the full assembly), the bulb may simply be burned out, or in rarer cases a dispenser control board fault can kill the dispenser light. Also check the light switch, the door switch, and the light socket — those three are common, testable causes and are often the real culprits when a fridge light not working looks mysterious. A quick visual check and a bulb swap will rule out the easy fixes; if the bulb is fine, use a multimeter to test the switch, door switch, socket, or board for continuity and voltage before buying parts. If you need replacement parts, enter your model number on RepairClinic.com to see the exact replacement light assembly, bulb, switch, socket, or control board that fits your refrigerator. This approach gets you back to a working refrigerator interior light without guesswork.

03 - Hotpoint 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.
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.
