    I inadvertently pulled out the waveguard mica strip from my newly purchased microwave, thinking that it was cardboard packaging (that's how it looked). It is now cracked and fits crookedly where it is supposed to be straight. I can't find where to buy a replacement for the Salton MW2027 microwave.

SOURCE: Arching when in use

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.

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.

If the magnetron is damaged, it will have to be replaced, too.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Sounds like the sensor for the door close was somehow bumped / damaged / dislocated when you knocked that vent cover off. It is very difficult to fix this, it requires taking apart the whole microwave. Will the microwave still function, the light will not turn off ever though?

Let me know

There is a piece of cardboard inside covering a metal panel, do I need to remove it?


Interior of microwave ovens are metal, never cardboard. Must be something used for shipping purposes, pitch it.

Why does my microwave arch at the wave guard


Typically most arcing in a microwave is caused by food splatter. A microwave cannot tell the difference between what is on a plate or on the wall or ceiling. Every food particle in a microwave will continue to cook until it turns to carbon and will attract the microwave energy and focus it to that spot and the unit will arc. Thorough cleaning of the entire microwave cooking cavity and removal of any burn or soot mark will commonly stop the arcing. If your microwave has a painted cavity, you can even use some very fine sand paper to remove any burn mark. Always cover what you are warming and really keep the inside of the microwave clean. If your wave guide cover is made out of the Mica board, and If it has gotten wet from cleaning or from splatter, it must be replaced. You can either order a new one or order a sheet of the mica board and cut out a new one yourself. If the microwave is arcing in the waveguide, generally the unit will need to be replaced. One quick test to see if the unit will work is to remove the bad cover and place a small container of water in the unit, run the machine of a minute or so and see if it still arcs. If it does, the arcing is in the waveguide area, if not it may have just been a problem with the cover. You can run the unit without the waveguide cover in place, it is only there to prevent splatter from getting into the waveguide, so removing it to test the unit is ok. If the area inside the wave guide shows signs of soot and arcing. You can try to wipe that out with some alcohol or lacquer thinner and then try it again. Good Luck.

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.

My microwave is making a cracking sound like if it had metal in it but i took everything out and its still making the cracking sound. What could be causing this sounds if microwave is empty?


A contaminated wave guide cover will crackle and spark.
They should be periodically checked, cleaned or replaced.
Contact Maytag for replacement parts.
Hope this fixes your noise.

The top plate inside the microwave sparks while cooking. We checked the dish we were cooking with, the papertowel that covered the dish. What could be causing this?


The wave guide could be dirty or damaged. Dirty oven interior can also cause sparking. The wave guide is probably not dirty if it's not on the interior of the oven . Some are behind the interior wall .

Sparks and strange noise when microwave is turned on even when empty inside. i have a ge jvm1850smss over the oven microwave.


YOU SHOULD NOT RUN MICRO WITHOUT ANY THING IN IT / THIS WILL OVER LOAD THE MAG TUBE . AND SOME TIMES FRY IT .. The sparking and arcing is probably a bad wave guide . this is sometimes caused by food splater / it gets in the cracks and corners and then cooks till it truns to carbon which conduts the micro's and thus arching .. clean it good and touch up any burns in the metal and repl wave guide cover. mm hope this will help .. mm

Our microwave fell to the floor and landed on its' corner. Miraculously it still operates but the metal cover is a little bent so it bows slightly on each side of the corner. If we can see light through...


Yes! hazardous to health,microwaves has a shorter wavelengths, it reflects or radiates.The gun or the magnetron is called MASER, sounds like LASER,Laser emits light energy while Maser -microwave energy.

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


Hi,

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

Arching inside microwave


un plug it right away.

there are carbon deposit near the wave cover. the arching is coming from the magnetron to any exposed metal inside the unit or any carbon deposit since carbon is already conductive, it is sensing it as a metal.

remove and clean the interior of the microwave. polished and paint all exposed metal that you will find in the interior.

then test again the unit.
