If your refrigerator light is not working, start by checking the light assembly since some manufacturers sell it only as a complete unit and a faulty assembly is the first thing to fail. Next swap in a known-good light bulb — a burnt bulb is an easy fix and worth ruling out before removing parts. A defective dispenser control board can also kill the dispenser light, so inspect the board for burned components and use a multimeter to check for voltage if the light still won’t turn on. Less likely but common, a bad light switch, door switch, or a failed light socket will keep the fridge light out; test each for continuity and for power at the socket to pinpoint the problem. Whether you need a replacement bulb, socket, switch, control board, or the full light assembly, enter your model number on RepairClinic.com to find the exact replacement part for your refrigerator and get step by step repair guidance to get the refrigerator interior light working again.

03 - Magic Chef 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.
