When your Sunray oven light is out, start by checking the light bulb or light assembly, then test the related electrical parts. The oven control board sends voltage to the light, although it is not a common cause. If the light socket or assembly receives no power while the light switch has continuity, the control board may be defective. More often, the light assembly needs replacement because its components may not be sold separately. A burned-out oven light bulb or failed halogen lamp can also cause an oven light not working symptom. Test the bulb or lamp for continuity, or install it in an identical socket. If the socket has power but the oven light still will not work, replace the light socket. A faulty light housing can cause the same problem when power reaches the socket or assembly. Always disconnect power before testing or replacing parts, and use a multimeter when needed. Enter your Sunray range, stove, or oven model number to find the exact oven light bulb, light assembly, socket, housing, halogen lamp, or oven control board replacement part for your appliance.
01 - Sunray 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.
