Is your Jenn Air oven light out? If the oven light is not working, start by checking the light switch (if present) or the oven control board, although it is not a common failure. The control board supplies voltage to the light bulb or light assembly. With a multimeter, check whether voltage reaches the light socket or light assembly. If the light switch has continuity but no voltage reaches the light, the Jenn Air oven control board may need replacement. Next, inspect the light assembly, which may require complete replacement because its components are often not sold separately. A burned-out oven light bulb is another likely cause. Test the bulb for continuity or try it in an identical socket. Some Jenn Air ovens use a halogen lamp, which can be tested the same way. If the socket receives power but the oven light will not work, replace the light socket. If the bulb or light board checks out, the light housing may be faulty. Enter your model number to find the exact replacement part for your Jenn Air oven, including the correct oven light bulb or assembly.
01 - Jenn Air 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.
