It may be that the high-voltage transformer or magnetron has failed and is loading down the voltage. The presence of smoke usually indicates a bad transformer.


I would try a toaster or toaster oven in that outlet to see if it works right. That's a good line load test.


If you don't feel good air flow, it can overheat and ruin the magnetron.

The sound you heard was an internal ARC/Short in the Magnetron which creates the microwaves, This is an imminent sign of complete failure, Due to the decrease in prices of new microwaves it is no longer economical to repair them so start looking for a good special on microwaves.

Wife was cooking food, she says she heard a big pow and saw a blue light in the MW. Now everytime we turn it on it jumps the breaker. Everything else works fine.

It sounds like the Magnetron that produces the microwave energy that heats the food has failed and shorted out which is triggering the Circuit Breaker due to the overload. You could try taking it to a repair shop, but with the cost of labour and parts these days, it is probably more economical to buy a new oven especially if it more than 5 Yrs old..

Suggest you pull the plug out, remove outer cover and place a cup of water into the micro. Set power to minimum then switch on and take note if the fan works or not. If not, switch off immediately and have it replaced(magnatron will burn out if left to run without fan.)

Everything works except the cooking part/no heating/turntable not turning, help!

you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt

Fan & Turntable start when door is opened.

sounds like there is a switch that is bad. you can go buy a new MW for about 200$ and in yours if there is a major problem then i would just go buy a new one but might be worth a repair man to come check it out

pleas do not poke around in the microwave as it carries a charge of 5000volts and can kill you even if not plugged in DON'T TOUCH THE WIRES WITH BRAIDS ON THE OUT SIDE if you must get inside of the unit
