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.

Your manual should address the issue of removing and cleaning the waveguide cover.

If for some reason you don't have your owner's manual, you can download GE owner's manuals and installation instructions here.

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.

GE Microwave oven is making popping sounds.


This is because the coating inside the oven or the wave guide has been damaged and microwaves are hitting bare metal and causing sparks. Take the light bulb out of it and when it is dark, put a glass of water in it and turn it on. If you can see the sparks then you know what needs to be repaired. You can buy microwave oven paint. It is special paint though, you cannot just use any paint. If you cannot see sparks then the area that is damaged is inside the unit and it should be taken in for repairs. If you don't fix it, it will blow out the magnetron and you will be looking at a new oven.

Can I fix a microwave oven that sparks when you turn it on? on Model JRS1130DSBB?


Generally once they start sparking it is the end of the microwave. If they are sparking in the cavity sometimes cleaning the cavity thoroughly will stop this. If it is in the wave guide. there really is no fix.

WHY DID MY MICROWAVE OVEN BURST INTO A FLAME AFTER 30 SECONDS ON HIGH POWER? TWICE. LMV1314B bought Jan. 2008


Hi,
Actually you don't need to replace the microwave, you just need to replace the carboard piece or "wave guide" and replace the magnetron inside the microwave behind the cardboard piece. The magnetron will commonly arc out to the wave guide if the wave guide gets something that splatters on it. The repair isn't cheap because the magnetron costs about $200 and the wave guide is another $30 or so, but if you replace both these parts you should be good to go again.
The magnetron usually have 5 years warranty, however you need to speak with manufacturer itself for the same.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Sharp r-930ak microwave oven is sparking


A dirty or damaged wave guide cover can cause sparks, fire and noises. You can order a replacement wave guide cover from many appliance parts websites for less than $15 in many cases. It should fix the problem.

I have a GE spacemaker. It releases electric volts when is turned on . Needs to be changed or can be repaired?


Hi,

Do you mean "sparks" inside the oven cavity when it is operating ?

If so, check for grease spots on the wave guide cover or scratches on the oven liner. Scratches can be touched up with touch up paint and wave guide cover`s can be replaced.

Hope that help`s, good luck.

GE Profie JE1860SH 04 microwave sparks


Our JE1860SH was also sparking after a few seconds. The GE tech pulled the upper round disk and found the problem. The plastic was burned and the round metal which is behind the plastic dome was arching with the frame. Lasted seven years expected more especially from a GE product. So my suggestion is to remove the dome and check it out.

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

Arcing inside microwave


your wave guide or door seal is defective

Oct 26, 2009 | GE Advantium 120 Convection/Microwave Oven

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!
