Oven Light is Out

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.

To determine if the light switch is defective, use a multimeter to test it for continuity. If the light switch does not have continuity, replace it.

The touchpad and control panel regulate the power supply to all of the oven components, including the oven light. If the touchpad and control panel assembly is defective, it won’t signal the oven control board to turn on the oven light. However, this is rarely the case. First, test the light bulb and socket. If the light bulb and socket are not defective, the touchpad and control panel assembly might be at fault.

The touchpad has a button that controls the oven light. If this button is defective, the touchpad won’t signal the oven control board to turn on the oven light. However, this is rarely the case. First test the light bulb, socket, and switch. If none of these components is defective, the touchpad might be at fault.

The 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.

The transformer might be defective. However, this is rarely the case. First check the light bulb, socket, and light switch. If none of these components is defective, the transformer might be at fault. The transformer is not repairable—if the transformer is defective, you must replace it.

The main 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.
