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 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.

I have a GE WES1384SM2SS microwave oven that shoots fire out of the right hand side.

Sounds like it is arcing there. Is there a plastic or Mica cover there?? If so that is the wave guide cover and it will need to be replaced and any and all carbon burn marks totally cleaned out to be able to save the machine. You can remove the burnt cover and run the unit with a container of water in it to see if it still arcs. If it does more cleaning will be needed if not, replace the covers with new ones and you should be good.

My GE microwave is starting to arc, You can see the arcs on the plate (I believe it is the wave guide cover) on the right side interior. Burn marks are evident on teh plate. Is it the waveguide cover or...

Some units use a plastic or fiberglass cover over the wave guide where the microwaves are dumped into the oven cavity. If this cover gets coated with food/grease, or soaks up grease, it can arc, or catch fire. If unit is still operating properly otherwise, I would suggest replacing the cover. You need to inspect the wave guide, also, to make sure it is still intact, and there are no cracks in it that would allow microwave radiation to escape.

Not heating

Remove the outer cover (pull the power plug first) and look for a blown fuse. If found, replace the high voltage diode and the 'stirrer' (a fan-like device located within the sheet metal wave-guide near the opening in the cooking cavity where the microwaves come into it). This stirrer has a plastic bearing that frequently arcs over and permanently shorts out the microwaves which blows the fuse. If no blown fuse is found, look for a loose or defective door-interlock micro-switch.

Arcing inside microwave

your wave guide or door seal is defective

The microwave starts, then stops after a few seconds, and smells

Remove the cover after pulling the power plug. Check the transformer and large capacitor for signs of overheating. If they look ok, then remove the sheet metal wave-guide from the area where the energy enters the cooking cavity. Under the wave guide is a fan-like device called a stirrer that has a plastic bearing. This stirrer bearing is commonly arced over (when the oven is operated with nothing to heat in it). Usually the bearing looks good, but has arced internally. Replace the stirrer as a unit. The machine can be operated with the case off and a cup of water for a load, but keep you hands clear. Look for smoke.

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


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

Clicking When Unit Starts

Q - When there is small amounts of food in the oven, arcing occurs right behind the plate where the wave guide comes into the oven. Sometimes it works well and sometimes you can't even put in a bag of popcorn. Any ideas? Could food have 'dripped' in here and be causing a microwave short?
A - Yes! Food splatter or drips can continue to cook and will carbon over creating sparks/arcs from the wave guide cover. Usually can clean up the food on and under the wave guide cover, if the oven liner has been damaged we usually lightly sand and touch up those marks with touch paint. Do not let it go for too long as damage to the magnetron end is possible as well :(   If the wave guide cover has been damaged, replace it!

System Arcs and Makes Electrical buzzing sounds

If it weren't brand new, I'd suspect arcing due to grease or food particle buildup on or under the stirrer (if equipped) or waveguide cover, or the turntable area.

But since it's new, I would suspect that the stirrer or another part may have been damaged or misaligned in shipping.

Your best bet with a new one is to get it replaced.

It's hard to put a price on peace of mind.
