If your refrigerator light not working or the fridge light out, start with the parts that most often fail: the light assembly itself, then the light bulb. Replace the bulb first—it's the simplest fix—and only swap the assembly if the housing or wiring is faulty. The page also lists a dispenser control board as a possible but less likely cause, so glance for burn marks or use a multimeter to see if the board is sending voltage to the light connector. More commonly you’ll find a bad light switch, a faulty door switch, or a worn light socket; test switches and the socket for continuity and power before replacing them. These checks cover the typical reasons a refrigerator interior light not working, and they give you a clear order of operations so you don’t replace parts unnecessarily.

03 - Modern Maid 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.
