Cooktop light not working

We installed the microwave and the light didn't work. I unscrewed the cover plate for one of the lightbulbs, and then the light started working. It worked for one day and has now stopped working. I can hear the relay opening and closing as I press the light switch from high to low to off. Any ideas of what might be wrong? Thanks!

Re: Cooktop light not working

Both bulbs went out at the same time on our Microwave. I replaced both bulbs, purchased from MCM around $15 a piece. Lights are back on and working.

Re: Cooktop light not working

We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

If you or a friend decide to look into it, we have critical safety information and disassembly information at our site, linked here on Fixya:

Whirlpool Microwave WMH 1163 XVS-0 How do you change the stovetop lightbulb?

Under the stove top should be a small panel the light emits from. One side of it should have a regular Phillips screw. Unscrew it and the panel should open. It is not hinged so you have to carefully work it open. Once open you should be able to see and then unscrew the bulb, I was able to find a replacement at Home Depot. The installed bulb was 40w, but I was only able to find a 25w replacement. Seems to work just fine though. Once replaced, just work the panel back on and screw back in.

Lightbulb on ceiling of oven went out. How do I

Hello :

1:Unplug the microwave oven from the outlet. Wait 20 minutes for the capacitor that is inside the microwave to discharge.

2:Unscrew all the screws around the casing by turning them counterclockwise.

3:Remove the cover by lifting off.

4:Locate the light bulb in the microwave. This will be located on either the right or left side.

5:Unscrew the light bulb by unscrewing counterclockwise. Some light bulbs are held into the socket by two notches; for these you will need to gently push on the bulb and turn counterclockwise to unsecure the bulb, then pull out of the socket.

6: Place your new bulb in the empty socket and secure by turning clockwise until tight, or if the bulb is one with notches on both sides, then guide the notches into the slot on the socket, push gently and turn clockwise until clicked into position.

7: Replace the cover and screw back on. You are now done and may plug back in the microwave.

Warning : Unplug the microwave before starting and wait 20 minutes for any residual electricity to be bled off from the capacitor.

Things you will need : Phillips screwdriver

good luck .

Same for us. The night light and work light do not work.

Simple screw driver to remove the cover plates on the bottom of the oven and the bulb unscrews. Install a new appliance bulb and your back in business.

Light no longer working

Most microwave ovens I have worked on the procedure is...
UNPLUG the microwave.
Remove the screws (along the bottom sides and the back of the oven) holding the the outer cover to the unit.
Remove the outer cover and the lightbulb will be visible.
Unscrew the bulb and head to the hardware store for a replacement.
Reverse above procedures.
Hope this helps.

I am having a problem installing the cooktop light on my Bosch microwave. It looks as thought the light "blew" and now I can't get the broken lightbulb out of the socket.

It's probably attached with hot glue to keep it from getting loose due to heat or vibration.

I would be sure it's unplugged, then use needle-nosed pliers to remove the leftover base from the socket.

Where is the light bulb located?

Unscrew the vent at the top of the microwave(2 phillips head screws)
inside to the right you'll see another screw holding a metal panel. Unscrew this and take the panel off and you'll see the bulb, which will unscrew counter-clockwise
