The part(s) or condition(s) listed below for the symptom Oven light is out are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
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.
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.
