Microwave oven part fallen off.

Most generally the waveguide cover just snaps into holes or slots and uses no screws. Some ovens use plastic rivets to hold the cover in place.

Waveguide Cover

If the microwave is sparking or arcing the waveguide cover might be damaged and shorting out. Try removing the waveguide cover and see if the problem goes away. If there are any damaged spots in the microwave ceiling or sidewalls, repair them and paint them with microwave oven paint. Replace the waveguide cover if it is burnt or if it will not stay in place.

Microwave Oven Paint

If the microwave is sparking or arcing on the side walls the paint might have chipped causing pitting in the metal oven wall. Use microwave safe paint to touch up any bare metal spots.

Rack Support

If the microwave is sparking or arcing near one of the rack supports, remove the support, repaint any bare metal, install a new support.

It sounds like what you are talking about is an issue with the waveguide cover. It is usually made of a material called Mica. Its purpose is to cover the aperture through which the microwaves enter the oven cavity from where they are produced by the Magnetron behind the control panel. It stops moisture and food particles getting into the "workings" of the microwave.

if your microwave is working ok and behaving itself then there is nothing to worry about, but there may be one of 3 problems that may arise which should be rectified.

1. Its fallen off.

2. It has a hole in it.

3. It is arcing or sparking during use.

In any eventuality it should be replaced. If it has fallen off or got a hole in it then there is the risk of food or moisture getting into the waveguide which will reduce the efficiency of the oven. If it is arcing or sparking then continued use will damage other components in the microwave including the oven cavity which could be costly to rectify.

If there are any issues with your waveguide cover it should be replaced. When new the mica sheet is rigid and firm. Over a period of time it absorbs moisture and gets food splatters on it. It then becomes soft and flexible. The cover can be replaced either with a suitable replacement made by the manufacturer of the microwave or if the old cover is in good enough shape to be used as a template, blank sheets of mica can be purchased and cut to fit.

I had the same problem with my microwave. There is a cover on the inside of the microwave called a "wave guide cover" which can cause the symptoms you described. It can be caused by grease or debris accumulating around or on the cover. Mine actually began to smoke and appeared burned in the top corner. It is very easy to remove and replace, and is pretty inexpensive and can probably be purchased online. They are model specific, so be sure to purchase the correct one for your unit.

Usually the covers are just cosmetic but to be sure you should do a leak test. This is nothing more than running around the microwave with a neon bulb while it is running. If it is leaking then it will light up and you should not use the oven as it isn't safe. If you don;t have a bulb most applience repair shops will do the test for you usually for free.Only takes a minute to do but is important to know it isn't leaking microwave energy out.

That is called the ceiling cover, also known as the waveguide cover, stirrer cover, or spatter shield.

It will definitely need to be replaced. It provides important protection for the magnetron.

Well microwave probably was too close to the ceiling and it wasn't getting enough air through and it got hot then bam you have a hole in your ceiling... if your microwave is completely ruined then don't bother with it just get a new one but if it works try moving it farther away from the ceiling.. good luck =]]

I would check the area around the ceiling of the microwave. There may be grease of other food buildup on the waveguide cover. Or the stirrer may be sticking or arcing, which would need to be replaced. This unit may be subject to post-manufacturing modifications, requiring a few new parts. You might check on this with GE Customer Relations at 1-800-386-1215 (8-6 ET). If they cover the cost of parts, great.
