Question about Whirlpool MH1150XMQ Microwave Oven

1 Answer

This morning, while running the microwave, an interior cover overheated and scorched/burned. There is a hole in the upper right interior, where I believe the micro waves come out. This is a squarish shaped, almost like cardboard piece that covered that hole. It is held in with 2 plastic rivets. I haven't been able to find this part on any of the diagrams online. How do I replace this part or can the microwave be run without this cover?

That is called the waveguide cover and it is there to stop moisture, steam and food particle from entering the magnetron or aerial and destroy the component parts.
There are spares available through Philips Agents or online from ebay or espares etc.
It is fairly innexpensive but essential!

Testimonial: "I haven't been able to find anything online for my model type, so I'll be visiting a local appliance shop tomorrow to see if they have any waveguides."

Why is there a burn hole inside the oven, on the cardboard?


That's actually a mica "window" (cover) for the microwaves to come out. And it sounds like the magnetron started arcing and burned a hole in that cover. Either that, or some food (frequently spaghetti sause) got splattered on it, and the microwaves heated it up so much that it burned a hole in the cover. Does the microwave oven still work (heat)? Do you see or hear any arcing? If the microwave oven still works and there is no arcing, you can just replace that cover. Check SearsPartsDirect.com or RepairClinic.com.

My microwave arcs every time I try to heat something. The silver colored plate on the interior right side of the cabinet appears to be burned. What happened and can it be fixed?


This arcing is caused by food splatter when something 'popped' or 'exploded' during an earlier cooking cycle. The food particle remained and every time the microwave gets used, this particle continues to cook until it turns into carbon. This can be as small as the tip of a pin. Carbon reacts very violently to RF energy (which is what causes the food to heat). You need to carefully remove the "waveguide cover". Clean it and check for a burned spot. You also need to inspect the inside of the "waveguide" once the cover is off. Clean it also. Make sure there is no grease or other foreign matter inside there and be sure not to leave anything in there (paper towel piece, etc..). If any of the paint inside the waveguide is burned, and if it can't be sanded off and touched up with catalytic paint, you need a new microwave oven. If the burned area is limited to the waveguide cover and you can't find a replacement, you can buy a sheet of mica material from a parts house and use the old cover as a template to make a new one. Also, "If you are on Gilligan's Island" and can't get any new material, you can cut the burned spot out and cover the hole on both sides of the waveguide cover with cellophane tape. Do this at your own risk but usually it works fine.......

A plastic container with hidden piece of metal caught fire in my Sharp r1490 and burned with a big flame. Several small holes were burned in the ceiling panel. Are we in danger of radiation exposure/ is...


The microwave oven is not safe to use, the fire has compromised the interior of the oven, if you run the microwave it will start to arc and eventually short out the magnetron, because the white enamel paint has been burned away. If you have holes in the ceiling there is danger of radiation leakage, for safety reasons the oven should be replaced.

Hi! the problem you have mentioned indicates that your microwave magnetron is not working. check for busted fuses.

Arcing inside and there is now a small hole on the panel side. Is this fixable?


Hi,

It looks like there's lightning (arcing) inside my microwave When you see arcing inside your microwave, it's because of food or liquid left in the cavity or on the wave-guide cover:

  • If the wave guide has any burn spots, replace it and clean the unit well.

  • If the cavity has any burn spots, spot-sand it smooth and touch it up with microwave interior paint.

Note… If there are any burn holes in the cavity, don't use the unit-seek help from a qualified appliance repair technician.

Thanks for contacting Fixya

GE spacemaker xl1800 microwave "burnt paper" smell


Hey
There are several things you can do to help git rid of that smell
First get a mild cleaner with bleach (soft scrub ect!) and clean entire oven inside and try getting that scorch mark off! a little pressure should lessen it ! (there is no filter inside! The plastic inside covering holds smells for a long time! you can also put a cup of white vinigar inside warm on high for 1 minute and leave in overnight!
Please take a second and rate my response
Thank You1

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.

A microwave needs all those surfaces to be fully reflective. those scorch marks greatly affect the magnetron. it will soon burn out . reccommend a new microwave.
