Question about Microwave Ovens
Hi, I have a GE micriwave/Convetion model PVM1790DR1BB when trying to microwave the timer and the light work but no other sounds. It will not heat a glass of water or spark with a metallic objet in the oven. What could be some potential problems?

I have this exact model with the same issue. I am a technician by trade on office equipment. I took the cover off where the door latches go in and there are 3 relay switches behind there. I adjusted the switches so the door latch would make better contact with them.

If you look at consumer affairs.com, there are many problems like this with GE microwaves. Not a good track record, experiencing problems with mine as well.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck

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

With the symptoms you
have, I would most strongly suspect a shorted high voltage rectifier
diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.
The diode is a fairly cheap fix, and your magnetron is still under the part warranty, but you would have to pay labor.
If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.
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.
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)
If it's within the magnetron portion of the warranty (5-9 years) but out of the original full warranty (1 year), G.E. will cover the part cost, but not the cost to visit you or the labor charge to do the work.
If it's within the mag warranty, G.E. should send you the magnetron to do it yourself. Call them at 888-239-6832 with your model, serial, and manufacturing date.
If nothing else, you can save about $50-75 if you remove it from the wall and take it to a GE-authorized servicer.
You can find a GE-authorized servicer by calling GE Appliance Service at 1-800-848-7620 or here.
Accessing some components for testing and possible replacement will require you to remove the oven from the wall.
If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.
You can download GE owner's manuals and installation instructions here.
