If your refrigerator light is not working or the fridge light is out, the most likely culprits are the light switch, the door switch, or a bad light socket; those three fail most often and are easy to test with a multimeter. Next, swap in a known-good bulb before replacing anything else, since a burned-out bulb is a common, fast fix. The light assembly itself can be defective, and some manufacturers only sell the entire assembly instead of individual components. A failed dispenser control board is possible but uncommon; inspect the board for burn marks and use a meter to see if it is sending voltage to the light connector before assuming the board needs replacement. If you need parts, enter your model number on RepairClinic.com to pull up the exact replacement light bulb, socket, switch, assembly, or control board that fits your refrigerator. This approach gets you troubleshooting quickly, keeps repairs straightforward for a confident DIYer, and helps a first-timer follow clear, testable steps.

03 - Americana 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.
