If it's less than a year old, it's still under warranty. If it's just over a year old, GE will still cover parts, but you'd have to pay for labor.

The most likely causes are a shorted high-voltage diode or a bad magnetron.

I press #1 and hit start the blower works and light comes on but no heat

Sounds like the magnetron circuit has failed. It is the part that generates the microwaves that heat the food. It often shorts out, and makes a loud humming or buzzing noise when it fails. It's not usually cost effect to replace since the part alone can cost as much as a new oven.

Loud buzzing noise with Whirpool microwave oven when it comes on. All lights, heating and fan seems to work but not sure why loud buzzing. What is the problem?

The loud buzzing you hear is the sound of the magnatron tube.That is what emits the microwave radiation and buzzing should be normal. The mag tube may be nearing its end at witch time you will hear no buzzing and hence no heating of foods. Replacement can be costly depending on the model so most people just opt for a new one. Hope this helps

Makes a loud buzzing noise and does not get hot

Have seen this many times.

Sounds like a bad CAP since a bad diode would blow the fuse and a bad mag would likely do the same thing.

Since yours is making the loud 60hz buzz you need to replace the capacator that will likely fix the problem. A $10 fix

Mwave made loud buzzing noise then didn't heat up anymore

When there's a loud buzz like that, it does not heat, and does not blow the fuse, it is usually a defective magnetron. Did it sound something like someone making a "gurgling" sound into a coffee cup? I think this has a a one-year warranty, with n five-year warranty covering the magnetron. You can find a local Amana-authorized servicer here:
