If your RCA oven light is out, the oven light not working is usually caused by a failed oven control board, light assembly, or light bulb. The control board supplies voltage to the oven light, although it is not the most common failure. Use a multimeter to check whether power reaches the light socket or light assembly. If the light switch has continuity but no voltage reaches the socket, the oven control board may need replacement. Next, the complete light assembly may be defective because some components are not sold separately. A burned-out light bulb or halogen lamp is another common cause, and you can test either for continuity or install it in an identical socket. If the socket receives power but the oven light still will not turn on, replace the light socket. A faulty light housing can also prevent the bulb or light board from working. Always disconnect power before testing or replacing parts. Enter your RCA range, stove, or oven model number to find the exact replacement light bulb, light assembly, socket, housing, or oven control board for your appliance.
01 - RCA Range/Stove/Oven Oven Control Board
The oven control board is used to send voltage to nearly all of the oven's electrical components including the lights. If the control board is defective, it may be unable to send voltage to the light bulb or light board, although this is not a common problem. You can use a multimeter to determine if power is reaching the light socket or light assembly. If power is not reaching the light socket or light assembly and the light switch tests positive for electrical continuity when tested with a multimeter, then the control board is likely defective and will need to be replaced.

To determine if a halogen lamp has failed, you can use a multimeter to test it for electrical continuity, or install the lamp into an identical socket to test it.
Use a multimeter to test for power to the light socket. If the light socket is getting power, but the oven light won’t work, this indicates that the light socket is defective. If the light socket is defective, replace it.
If you've determined the light bulb has not burned out or the light board appears to be functioning normally, it's possible that the light housing the bulb or board is installed in is faulty. Use a multimeter to determine if power is reaching the light socket or light assembly. If power is reaching the socket or assembly, then it's likely the light housing is malfunctioning and will need to be replaced.
