Whirlpool had a recall on many microwaves due to this problem. Call Whirlpool and see if yours is one of them. My microwave model was mh7140xfb and was on the recall list.

Quite often this is due to grease or food particles stuck somewhere in the cavity of the oven or stuck on or behind the waveguide cover.

The waveguide cover (also called a spatter shield) is usually on the right side of the cavity and is about the size of a playing card and often held in place by a plastic rivet.

In some models it is a larger stirrer cover type made of thicker plastic in the ceiling of the oven.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If your waveguide cover is burned, it will need to be replaced.

It provides critical protection for the magnetron.

Your owner's manual may show you how to remove the 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!

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.

Replacement of the Cover Inlet plate inside the microwave, this is part # 8184604. I have the part, I just need to know what to do to replace it. Thanks,


Hi


To locate the inlet cover, look towards the interior side of the microwave next to the microwave display. The inlet is typically located near the back of the microwave, in the middle of the wall.
Unplug your microwave from the electrical outlet and remove any food or containers.

Wipe the inlet cover, typically located on the right side of the microwave in the middle of the wall, with a damp cloth. The cover must be kept clean or it will not protect the microwave.

Dry the inlet cover with a soft towel.

Leave the microwave door open for several hours to air out the inlet cover.

Examine the inlet cover for wear and tear. If the cover has too much damage in the form of scratches or holes, it may need replacement.

Remove the inlet cover, if desired. Insert a putty knife under the plastic nail that holds the inlet cover in place. Pry out the nails and set them aside. Pull out the micro plate in front of the inlet and set it aside. Remove the inlet plate.

Install a new inlet plate. Slide the new inlet cover into its place. Replace the nails back into the side of the microwave by aligning them with the holes of the side.

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.

Light bulb burned out in microwave oven


Most likely you're going to have to dismount the microwave and remove the outside cover to get to the bulb. This is a fair amount of work but is not rocket science. I'm not famliar with your particular microwave, but it's probably that way. If it's any comfort to you, light bulbs are usually not covered by warranties or service contracts.

It won't hurt to run the microwave without a bulb.
