With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

Here are some links you or someone you know can use for test help, but read their safety warnings first:

(if it's not shorted or burned, it's probably okay)

To remove it from the wall, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Microwave smell like burning rubber


Good Afternoon Friend,

I understand that you are receiving a burning rubber smell from your Frigidaire microwave. I also see that your appliance will run for a couple of seconds, and then you hear a weird noise, followed by a burning rubber smell. I suggest contacting your local authorized technician, especially when dealing with your microwave. They will be able to diagnose your appliance and determine what is causing that sound as well as the burning rubber smell. Hope this is helpful.

-Best Regards-
WP

Burning smell and loud grinding noise


If that grinding noise sounds a little like gargling into a coffee cup, that's a defective magnetron.

We were using the microwave the other night and it started making a loud noise like the fan was running (although the fan was not). We let it sit for awhile and try to use it again but the noise came...


The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

This sounds like the magnetron is failing, with a typical smell and a loud noise, there are two additional parts that can be a factor, the high voltage capacitor and diode. To pursue this you will need an appliance repairman or tv technician, the parts and labor will probably run the cost of a new microwave oven.

Makes loud noise when running like a high pitched noise


You have a bad magnetron. Just replace the unit. It will cost more to fix than to buy a new one. There are great deals on new microwaves now.

GE Spacemaker XL1800(JVM1850CF001) - Loud Humming noise


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.

GE Spacemaker XL1800 first no inside light followed by loud noise


I agree that the light is unrelated. 99.9% chance you have a bad magnetron tube but it is covered by either a 5 or 10 year parts warranty through GE. Call GE Factory Service at 1-800-432-2737 or schedule online at www.geappliances.com
