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.

If your brand and model are not shown, Please reply back with your brand and model number so we can help you.

SOURCE: I've taken off the wave

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.

Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

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.

While i was trying to prepare some coffe in the microwave after 2 minutes i opened the micro and the coffe was all over and now it's not functioning well? Can it be repared ?


Yeah a kind of. If the wave cover plate is only went bad(A rectangular plate inside the food chamber).
If you have little idea how to use voltmeter then only you can try to fix it.Otherwise,without any experience it is very risky.
First check the magnetron which produce microvave.(check two terminal resistance in isolated sysem).MAKE SURE YOU DISCHARGE CAPACITOR FIRST .MICRVAVE CONTAINS 5000V IN IT.

If magnetron is good then just clean the wave guide and replace the rectangular plate(wave cover).

it should work okay then

Thanks

Under the inside cover (right side) i see what appears to be burning when operating unit - is there something behind that removable cover that can be replaced or repaired to solve the...


Replace the cover as it is obviously dirty with carbonised food particles. Don't use it without a new Wave Guide Cover or permanent damage to the magnetron/aerial may result.

I have a GE Microwave Oven/Dual Element Browner Model # JES1288SHO3. The inside cabinet is arching through the wave guide panel. DAVE IN LA.


Hi Dave in LA,

The wave gude cover is replaceable, the part number is1085082. The reason for arcing through is typically a splatter of food stuck to the cover and then the heating waves overcooked or burned it. Carefully replace the cover (panel), look for any burned spots behind the cover, if the wave guide is burned through, the Microwave is unrepairable. If the waveguide has small arc spots you can carefully clean (sandpaper) and use touchup paint to recoat. I hope this helps and if it does, please let us know!

Microwave oven part fallen off.


There are nylon push-in fasteners that snap into place. If there is a shop that works on microwaves, they will generally have them. Over time these fasteners get brittle and crumble away. Another option is to use nylon screws, if you can find some the right size. I don't recommend metal screws as they may arc in the cooking cavity. Using the microwave without the cover will result in spattered food getting into areas that can't be cleaned.

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
