I can see sparks inside the oven. There is no food scattered on the inner wall of the oven which could cause it. Could you please tell me what the possible reason may be?

SOURCE: Paint damaged in side microwave oven

1) How is the cavity damaged? Is it just peeling paint, or is it rust? If it's rust then the microwave could be dangerous.

2) The antenna cap usually has a small hole in the centre, but if there are any other holes in it the magnetron itself could be damaged, and holes caused by the magnetrin arcing.

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.

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 metal of the oven wall is burned or chipped, the area will first have to be sanded smooth and cleaned 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 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 apply paint.

If your waveguide cover is burned, it will need to be replaced.

It provides critical protection for the magnetron.

Microwave is arcing and making a popping noise as if something metal was in there while cooking.


I will assume that you do not have any metal items or bits of tinfoil lying around inside the oven.

If the sparks are happening on the inside of the microwave's cooking area while you are cooking, then make sure you clean the inner surfaces really well. Be sure to remove any cooked on food particles that may have splashed up during cooking.

Most likely you have some corrosion or dried food debris inside the cooking area, or perhaps even some food particles stuck to your WAVEGUIDE COVER PLATE. A dirty waveguide cover plate can certainly cause the arcing and sparking you describe.

If the thorough cleaning does not work, you may need to replace the waveguide cover. Here is a link to a short video that shows you exactly how to replace the wave guide cover yourself:

Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the video at the website indicated.

If the sparks are coming from somewhere other that the cooking area, then your unit may need more significant electrical repairs or service.

Door glass is lose and seal is leaking..moisture is forming on inside of glass


That is normally caused by the clear plastic adhesive cover either having been removed or missing. It covers the perforated door inner and stops condensation and food particles from getting inside the door cavity where is cannot be cleaned.

Turned it on to heat food and make a loud noise , did not heat food and have electrical short ordor.


there is something metal inside that is causing this look for any screws or anything that may have been switch with a repair. what happens is the metal causes the microwaves to reflect back to the magnetron instead inside the food causing noises and sometimes sparks and odor. find the metal object remove it and this should solve your problem

GE JE2160 31/2 years when it is turned on sparks fly from the cover plate located on the right inner wall. If it can be repaired is there an estimate of cost. Thanks gm.eiland@gmail.com


All you need is a new WaveGuide Cover. It is fitted with usually a screw or plastic clip and is fitted from inside of the cavity, where you place your food to be cooked. No taking anything to bits, just the cover.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

The information is normally free of charge.

I hope this helps.

My Whirlpool over-the-oven microwave generated a "pop" sound and red flash last night -- it seemed to come from the left side, where there is a grid of small circular vent holes -- while warming...


Sorry to read about your problem, I hope this helps you out.

This can be normal, if you have grease or food stuck on the side walls, just clean entire oven area,

some cooking containers are more apt to causing sparking than others.

If it does it again, i would suggest you call a service company, But your unit can be replaced for around $150.00. So I dont know if it would be worth it.

Microwave sparks then will not work. Could it be the fuse? It is a Whirlpool.


It is tthe magnetron having the spark sometimes due to an insulation leak in the fitting .
Please check the spot where the magnetronis fitted to the cabin. Inside of the cabin there is a insulation cover and if some food particles are stuck on it due to non usage of food cover, then it is possible that the conduction of the food on this is smoking or causing an insulation break. So clean and remount the magnetron if not change the unit if the estimation is reasonable.

Microwave sparks inside oven in the area of the sealed compartment when it is started


If unit was run for long time with food on walls and not cleaned off, it is possible that the unit was burned in a spot where the food was and if there is metal frame under that part for the finish it will spark. Check closely for burns, if it is sparking due to that problem, junk it. It is a dangerous condition.

Microwave oven defective


It's actually a stirrer. Its purpose is to scatter the microwaves to ensure even cooking, similar to the way a turntable does in other models. Having a stirrer instead of a turntable allows for a bigger dish.

 

The sparking is usually caused by deposits or grease or food debiris which heat, reheat and arc.

 

If the oven is used very long without the cover, that debris and grease can get onto the magnetron and ruin it.
