If your Brown oven light is out, start with the light assembly and light bulb, which are the most common causes of an oven light not working. The bulb may simply be burned out, or the complete light assembly may need replacement because its components are often not sold separately. A failed halogen lamp can cause the same problem on models that use halogen lighting. Next, check the light socket and light housing. If the socket receives power but the oven light stays off, the socket or housing is likely defective. The oven control board is another possible cause, although it is less common. This board supplies voltage to the oven light and other electrical components. Use a multimeter to check the bulb for continuity and verify whether power reaches the socket or light assembly. If the light switch has continuity but the control board is not sending voltage, replace the control board. Enter your Brown range, stove, or oven model number to find the exact replacement light bulb, light assembly, socket, housing, halogen lamp, or oven control board for your appliance.
01 - Brown 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.
