Question about Whirlpool MH1150XMQ Microwave Oven

MH1150XMQ Lower Light Stopped Working

The light that shines down over the stove went out. I went to change the bulb and the glass part broke off, leaving the metal part in socket. After trying to get it out, ruined it and had to replace the whole light socket.

I took the old socket off, leaving the two wire leads exposed and they touched, causing a little electrical short (leaving little scorch marks on metal ends of leads). I then (should've done this first - doh!), cut the power to the microwave and installed replacement socket, slipping the leads back on the prongs of the new socket, but the light won't work at all.

I checked the only fuse I could find in the unit (behind the control panel) and it was okay. Does anyone know if there's more than one fuse in the unit, and where it may be - or do you know any other reason that would keep the light from turning on now? Really would like to get that lower light working again. Thanks for your help.

    I have the same problem except I'm not getting any power to the unit what-so-ever!

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail 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.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa.

Feel free to contact me directly.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

The cover for the oven light has broke leaving the screw part inside cannot get it out.


If you mean the glass dome of the bulb has broken leaving only the metal bulb base, you will need a medium size long nose plier to grip the edge of the bulb base, you can then gently rotate counter clockwise to remove.
ENSURE THE APPLIANCE IS ISOLATED FROM THE MAINS SUPPLY BEFORE ATTEMPTING THIS !!! PULL THE PLUG !!!

This is an over the stove microwave. Need help replacing the light bulbs on the bottom of the microwave.


Disconnect the power and get a flat bladed screw driver to remove some of the bulb base away from the socket. Insert long nose pliers into the area created and turn base counterclockwise to remove.

You could try the potato trick. Take a small to medium potato. Cut off an end of the potato. Press the cut end into the broken lightbulb and unscrew the rest of the bulb out.

I cannot tell how the 2 bulbs (surface light(s)) detach. One of them broke when I was trying to remove after it had burned out, and the glass part of the other bulb turns freely and is very loose and...


Unplug the microwave oven and get a needlenose plier and a flashlight. Wear some hand protection since you are working with broken glass.

Most of the bulbs I have seen are screw thread mounts.

For the bulb with the broken glass, use the needlenose plier and try to find the screw thread for the bulb. It should be screwed in to the lamp socket of the microwave. Carefully grab a hold of the outer edge of the bulbs screw thread and turn it counterclockwise to loosen it from the base. You may only be able to turn it a quarter turn before letting go of the bulb's thread and getting a grip on a new position to continue turning. Inch your way to remove the broken bulb's thread.

If the other bulb still lights up, I'd leave it alone.

Stovetop lamp sockets very brittle and are disintegrating.


In effect (given the unit is wired correctly) without insulation on the socket, you have an exposed neutral wire in your oven -- this is certainly not as dangerous as an exposed hot wire, but does present risks. I recommend replacing the light sockets -- you'll sleep and cook a lot better.

BROKEN GLASS COVER UNDER NIGHT LIGHT


SAME PROBLEM FOR ME...I REMOVED THE BOTTOM COVER AND FOUND THAT ONE LIGHT WAS NOT FIXED AND WAS LOOSE AND WAS TOUCHING THE GLASS. THIS HEAT WAS WHAT BROKE THE GLASS COVER. CLOSED INSPECTION SHOWED THE LIGHT SOCKET WAS TOO LARGE FOR THE CLIPS AND WERE NOT SECURED WHEN PURCHASED. I GOT SMALL SCREW AND NUT, BENT CLIPS SO THE SOCKET HOLE MATCHED THE HOLE MADE BY THE CLIP AND SECURELY ATTACHED THE SOCKET. THIS WILL SECURE THE LIGHT AND KEEP IT FROM TOUCHING THE GLASS..........IF I CAN EVER FIND A GLASS REPLACEMENT....MAY JUST HAVE ONE CUT. NOW THE PROBLEM IS TO REPLACE THE LIGHT AND MICROWAVE FUSE WHICH WAS BLOWN WHEN THE GLASS BROKE.

Broken bulb


From what others have said, it will come out, but you have to use some strong good needle nose pliers to turn the base in the socket.

Broken bulb


Get yourself a cork from a bottle of wine (wait to drink the wine until after you've removed the bulb!). Now, with the power plug REMOVED from the wall socket, gently but firmly press the cork into the broken bulb. You should now be able to screw the broken bulb out of the socket. If there's not any bulb glass or shards or anything else for the cork to grip, you may need to insert a small pair of pliers into the socket, and with reverse pressure (i.e. pulling the handle apart as opposed to squeezing together) you may be able to remove the bulb. And if that doesn't work, well, keep trying. You just need to be creative. Try using needle nose pliers and grabbing the edge of the bulb socket and gently work to loosen (remember lefty loosy, righty tighty) turning counterclockwise to remove.

Broken light bulb


First of all, always disconnect the oven from the line before you remove or install bulbs, otherwise, you can damage the control board. We repair them all the time because of this.

Surface lights


I also have had a problem with the glass part of the surface light bulb separating from the metal base when trying to change the bulbs under my G.E. Spacemaker Microwave.. I see someone used a carrot or potato but I had not seen this suggestion before I whittled one end of a wine cork small enough to insert into the metal part of the old bulb stuck in the socket. It also worked great and in no time I was able to get the old base out and replace the bulb. I'll save the cork for next time because it seems to happen to at least one of the bulbs everytime they need to be changed. DON'T FORGET TO UNPLUG THE MICROWAVE FIRST!
