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.

My new GE over the range microwave works fine but has a loud buzzing/humming noise when in use
This sound you describe is not normal and should be checked quickly, even if it means returning the item.

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..

If the sound is a bit like angry bees but muffled, then the magnetron is on its way out.

If there is no heat but all other functions work, then the magnatron is likely faulty. The magnatorn provides the heat. You can get one at repairclinic.com or partselect.com

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

LG LMVM2055: Cooked itself?
First you will need to answer a few quick questions between yourselves.
  1. Do you have life insurance?
  2. Is it enough for the wife and kids to survive on
  3. Whats the number for 911
After you answer all these questions, then pick up the microwave, and take it for a long drive.
There are bits inside there that will happily kill you days after it has been turned off. (some even weeks)
For the cost of a replacement in this case, it's not worth it.

It sounds like there may be a blown fuse. The back of the mw oven will have to be removed to check. Some ovens only have a thermal fuse and not a traditional glass fuse. If that is the case you should call a technician to repair it unless you know how to use a soldering iron.

You're on the right track. That panel is the waveguide cover.

This is usually due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover in the waveguide just out of sight.

It can be fragile, and the metal edges 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 smmoth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

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