Kenmore over the range microwave. Cooking on the stove and had something in the microwave. There was a very loud spark/pop sound and now it will not heat at all. Replaced the magnetron/checked the capacitor and replaced a couple fuses. Still no heating of foods. Any help???

I had an arcing sound coming from above the cardboard panel inside the microwave. When I saw it sparking I took the cover off and saw that these two aluminum looking things had come loose. I removed the cover and did a fair bit of 'fine tuning' to get it working again.

Hi,
Here is a tip that I wrote to give details about why your cooktop will not spark to light the burners..

you have done well out of the oven . it sounds that certain components are well worn and probably no able to get parts best advice it time to buy a new one

Okay, first we need to separate the situations. You were boiling water on the stove and had the range hood fan running to **** up the steam. Then you put something in the microwave to heat and you heard a pop and then zip-o.

The water on the stove has nothing to do with the situation, the fan you turn on is not part of the microwave, so it has nothing to do with the microwave.

The pop you heard and then the humming suggests the magnetron failed. You said you found a blow fuse and replaced it and still nothing, right? The magnetron is the most likely culprit...I would think it is safe to say that the magnetron shorted and drew enough current to blow the fuse.

Replace the magnetron and if that doesn't work, let me know here. Good Luck!

I have a GE Profile Spacemaker model JVM3670WF001, purchased I think in 2003. Pop sound, no Heat. Light goes on, carousel goes around,
Repair or new microwave

Hey,
Try this
Probably a high voltage diode popped because contaminated grease eventually built up and made a path for a high voltsge arc to occur.. To confirm,take the outer cover off the microwave and discharge the high voltage capacitor by shorting its terminals. Then pull the plug off the magnetron side and place it near the magnetron socket. Now turn the microwave on and push the connector on the magnetron with a chopstick or a long insulated screwdriver. If no arc when you do this this confirms a bad diode.



please rate my suggestion..

Is it safe to use your microwave if it pops like this all the time randomly... And sometimes lights up in the back like a spark or something???

I would say the high voltage diode blew.

I would check their Web site for links about parts, spares, or service.

This is almost certainly a blown high voltage diode.
