    I called Sears and this is the only one they offer. It came with a large white plastic piece and a smaller yellow plastic piece. A piece of what appears to be a grey looking sandpaper and some glue. I just dont' know how to put it on. I don't know what the glue is for.

Try replacing the screws with larger ones. Maybe you ordered the wrong piece, if your microwave comes with a mica cover (A fine, square piece of mica) and you received a plastic one, you will need to get the right piece or adapt the one you received.
You can get the mica cover on any microwave service.

    Could you post a picture of the parts received and the waveguide of your microwave oven? So i can figure out how to install it.

Kenmore microwave is sparking when you it start and then goes to pause


see this steps and fix it. God bless you
If you see arcing or sparking inside a microwave, turn unit off immediately. Arcing can be caused by having something metal in the oven cavity touching a side, an oven shelf is touching the side of the cavity, an oven shelf support has broken, microwave waveguide, or bad magnetron.
If your microwave has a shelf in it, and you do not use it, keep it out. If one of the shelf supports breaks or comes out, the microwave will arc where the support was. You will have to sand the spot down, paint with appliance paint and re-install support. If the shelf shifts on the support and touches the side it will arc.
Your magnetron waveguide will either come out of the top, or side of the oven cavity. Some will have a stirrer in it(mostly top waveguides) with a panel over, or just a cardboard type cover over it. Over time, the stirrer cover can become warped from the heat which will expose the stirrer's metal shaft which will then cause sparking. These covers and stirrers come in a kit and can be replaced from inside the oven cavity.
Your cover over a side waveguide is coated with a substance on it, and overtime this coating can come off from the heat and moisture in the microwave. These waveguide covers are very easy to replace from inside the oven cavity. Touch up any paint that may have chipped or come off because of the arcing.
If your waveguide cover and/or stirrer are all OK, then the spark is coming from your magnetron. The antenna on your magnetrom has overheated and burned, sending the microwaves out at the wrong angle. If you catch this microwave oven repair early enough, you can usually get by with just replacing the magnetron. If the arcing has caused servere damage inside the waveguide, you will need a new microwave. Waveguides are not replaceable and most you can barely see into them, let alone sand and re-paint. In this case of microwave oven repair, when you remove the magnetron, you will see the burned antenna, or your magnetron will fail the test below.

see the guide for test the magenetron and another component.

There is a pad on the interior right side that is made out of cardboard type of material. Seems very flimsy. Does this stay in there? What is its purpose?


That piece is called the waveguide cover. In many ovens it's made of plastic. In others, like yours, it's a mica sheet and does seem rather like cardboard, and is brittle. It's there to cover the hole where the microwaves enter the cooking cavity, so no food particles or grease can get in. The oven can work without the cover, but it's potentially unsafe. Arcing and overheating can result, and the magnetron tube (the microwave source) can be damaged, if food buildup occurs in the waveguide.

Replacement waveguide covers are available for many models, and you can get pieces to make your own if you can't find the exact part. Search the Web for "<your make and model here> waveguide cover". Sears parts and Appliance Parts Pros are good places to start looking, and you may be able to find a suitable replacement if you have an appliance parts store in your area.

Is it dangerous to use the microwave without a duct cover


Yes, the waveguide (duct) cover protects the waveguide and the magnetron from damage caused by grease and food particles getting on them.

The waveguide cover (also called a spatter shield) 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 area is charred or chipped, the area will first have to be sanded smooth and cleaned and dried thoroughly.

If the cavity metal of the oven is cracked or split, you can use a small amount of steel-based epoxy such as JB-WELD to patch the crack or hole.


Once that dries thoroughly, you can sand it very smooth.

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.

It provides critical protection for the magnetron.

That's the waveguide cover, a critical part of the oven.

This arcing is usually due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

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

Mokes when re-heating food in plastic microwavable dish


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.

It may also be in the area of the turntable support, coupler, or motor.

The waveguide cover (also called a spatter shield) is usually 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 the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

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. It provides important protection for the magnetron.

Removing microwave waveguide cover


Okay...if you are talking about the center cover that fits in either the overhead of the microwave cavity, or along one of the walls, those rivet like things you mentioned, are plastic and the center locking pin simply pulls out with the aid of a small screwdriver. Once you carefully pull the locking pin out until it stops, take the same small screwdriver and use it to gently pry around the outer ring and the locking tab should come right out. If you are careful you should be able reuse them. I have done this before. Try to avoid handling the interior of the waveguide itself. Look for any scorch marks. Some discoloration is normal (kind of like a gray streaking color). However, if it is burned excessively, the waveguide is probably shot. The high voltage capacitor is not located near the waveguide cover, so you should not have to worry about discharging it. It is located BEFORE the magnetron. Unplug the microwave oven as a safeguard. I hope this helps you.
