Question about Emerson Microwave Ovens

Open Question

My microwave # MW9325sl sparks as if it has foil in it. It seems to be coming from a paper type shield that is inside the oven that has several burned spots on it. How can I fix this problem?

SOURCE: Dacor Microwave

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

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

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 the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

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

The part would be much cheaper if you get the Sharp version (these ovens are made by Sharp) instead of the Dacor branded part.

The model DMT2420 is essentially the same as model R440D / R540D.

The Sharp part number is PCOVPB085MRP0 (zero on the end) and you can order Sharp parts from Tritronics at http://www.wehaveparts.com

SOURCE: Microwave door has burn spots on the glass of the door...

The brown spots are usually grease / smoke deposits. Usually there are indeed two sheets of glass in the door. If the grease is not arcing or smoking, and the metal screen / mesh (that blocks microwave leakage) is not damaged, then it's likely better left alone. It might be useful to boil a few cups of water with a little vinegar inside the microwave to help dissolve the deposits. In case you want to take it apart, I have attached a photo from a similar model that illustrates disassembly of the door. It is not necessary or advisable to remove the door or hinges when disassembling the door.

If the sparking has stopped, that should be fine.

If you have a burned spot you may need to sand it and repaint it with appliance paint from Wal-Mart, etc.

You can probably replace the shelf bracket / hook if it's still available.

If you'll post your brand and model, we'll see if we can steer you toward a source for a new shelf bracket.

If it's a Kenmore, you can probably find an exploded view by entering your FULL model number here: http://www3.sears.com (the 3 is correct)

SOURCE: interior cardboard/foil piece fell off revealing small chamber inside oven--still safe?

This is the mica or plastic waveguide cover. It protects the waveguide and magnetron form grease and food particles.

Assuming you're going to scrap the unit, carefully clean the area around the outside of opening (watch for sharp edges) with a lightly damp soft cloth.

Then use alcohol or a hair dryer, etc. to be sure the area is dry.

Then you can use a couple of strips of clear packing tape to cover the opening and trim it with a razor blade so only about 1/4" or so extends out from the opening.

Note that I only recommend this procedure on an oven that is going to be scrapped. If the oven will see continued use, a new waveguide cover should be purchased.

No, that is the "waveguide cover".

It provides very important protection for the magnetron.


And always keep it clean according to your manual's instructions.

If it sparks inside the oven then look inside for any powder paint missing... if so discard. If you has metal shelves or tin foil then don't put metal in when on microwave setting. Some of these metal shelves are for a microwave that is also a convection oven but only in the convection oven setting.

Look in side and make sure there is no pieces of aluminum foil or metal hidden inside. If not I would not use until you have a appliance repair person look at it.

I have a Panasonic microwave and it has rust inside is that dangerous?


It should not pose a hazard as far as operation goes.. only if it becomes a sanitary issue..

Clean the interior per mfg suggestions.. and you may have to clean it more often now that you have this issue.

Microwaves cannot travel through metal.. you can actually use small pieces of foil (flat pieces) in most microwaves to shield items.. without any issues.

Best of luck

The problem that you are having is that the magnetron inside the microwave is shorting out to ground and it will find the shortest path to reach whatever has metal in it. Replacing the magnetron will solve your problem altogether and you need not do anything else different and continue using your metal racks.

When we first turn on the microwave there is like a mini-explosion and a fiery spark, but after that the microwave goes through its cycle and cooks the food. But we are afraid to try it again.


pls do not use any aluminum or metal material INSIDE the microwave, this can cause the problem

I assumed, but pls consider the ff info...

Be sure to use nonmetal utensils in the microwave.

For microwave cooking, cut meats and vegetables in uniform sizes to make sure that they cook evenly.

Paper plates, cups, and napkins can be used in the microwave. But don't use foil-lined paper products, paper towels that include nylon or synthetic fibers, or newspaper.
When using plastic roasting or cooking bags in the microwave, discard the wire twist tie and use a plastic fastener or a piece of string instead.

To ensure that food cooks fully and evenly in the microwave oven, stir food and turn dishes periodically while they're cooking.

I thought I had answered this, but maybe the reply didn't post... Vent cap? Could you be more specific about what you tried and what the noise is like - where it seems to be coming from? It looks like on some of these models, the high-voltage section emits some interference which some people are blocking with a foil or metal shield. If they do that, they should definitely insulate it to prevent shorts. Another cause of vibration on these models is a fault in the stirrer located above the cover on the ceiling inside the cooking cavity. Feel free to post back so we can help further.
