SOURCE: Microwave makes a loud noise while using.

After you turn it on, it's a loud noise like it's coming from the fan, but other then that it works wonderfully.

Chances are you have a bad magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

If all of your door switches check out, replace the magnatron, capacitor, and diodes.

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

SOURCE: Microwave not heating food and is making loud noise.

You have burned out the magnatron (heating element) which is common on GE microwaves. most service companies will charge about 200-250 to replace it
