Is your Garland oven light out? The problem may be in the control board, light assembly, bulb, halogen lamp, light socket, or light housing. The oven control board sends voltage to the light circuit, but a defective board is not a common cause. Use a multimeter to check whether power reaches the light socket or assembly, and confirm that the light switch has continuity before replacing the board. Next, inspect the light assembly, since its components are often sold as one complete part. A burned-out oven light bulb or failed halogen lamp is another common cause. Test either part for continuity or install it in an identical socket. If power reaches the socket but the oven light still does not work, replace the light socket. If the bulb or light board works but the assembly housing is damaged or fails to deliver power, the light housing may need replacement. This troubleshooting applies to Garland ranges, stoves, and ovens with an oven light not working. Enter your model number to find the exact replacement light bulb, assembly, socket, housing, halogen lamp, or control board for your specific Garland oven.
01 - Garland 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.
