If your Frigidaire refrigerator light is not working, start with the simplest fix: replace the light bulb. A burned out bulb is the most common cause, and the page even recommends swapping the bulb before replacing other parts. If a new bulb still won’t light, check whether the socket is getting power; if the socket is powered but the bulb stays dark, replace the light socket. Next test the light switch and the door switch with a multimeter for continuity; faulty switches often cause the fridge light not to come on when the door opens. Some models use a sealed light assembly that may require replacing the whole assembly if the internal wiring or housing is bad. It is unlikely but possible that a dispenser control board issue could affect a dispenser light, so inspect the board for burn marks or use a meter to verify voltage to the plug.

03 - Frigidaire 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.
