This part is sparking / arc . Started with microwave shutting off after 4 secs . We removed the cover and turned microwave on and saw spark coming out of this box . Box says hig voltage


Magnetron, high voltage capacitor, or high voltage diode fault is likely. Please see my additional comments on your other post. Don't play with these machines... Extremely high voltages are in this area of the machine.

Loud noise when cooking


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.

It sounds like the main transformer has failed. It would be cheaper to replace the whole microwave than repair this one. Sorry to be the bearer of bad news. Hope this helps. Good luck.

Yesterday, I went to use the microwave and as I pushed start, I heard a loud pop and saw sparks behind the vent cover. The microwave light and turn table work fine, but it does not heat. Is it repairable?


sounds like your magnetron went out . check how old it is, sometimes the manufacture gives a 5-10 yr warrenty on part if no warranty on unit then it may not be worth fixing depending on how much u spent on it. part roughly 89.99-139.99 labor 85-165.00 depending on who u use and were u live. hope this helps . thanx..

Saw sparks and heard a pop noise when we hit ''start'' on microwave


We just had the same problem - spark, loud noise, and then dead. At first I replaced the ceramic fuse and the same thing happened immediately. A local appliance store tested the transformer and found it was "bad." I purchased a used transformer from the store for about $35. I installed both of these myself with little effort.

Microwave shuts off after running for five minutes


I'd be careful because you do not know what caused it to spark. How old is the microwave? Do you need a new one?

We had sevseral boiling pots going underneath the over the range microwave without the exhaust fan on while also cooking in the microwave, we saw sparks in the microwave and it went dead. now nothing...


The main power fuse inside the MW may have been blown from the steam shorting out the circuitry. If so this fuse probably can be replaced. Lowes has replacement fuses.
