For the smell, do a Google search for "smell microwave" or "odor microwave" for many great tips.

If you need a new turntable support, you can order Sharp parts from Tritronics at http://www.wehaveparts.com

It's part # FROLPB017MRK0

It is my understanding that you can't get parts for a Welbilt Microwave anymore. The good news is that you can make one work from another m/w. Take your shield to a local appliance parts dealer and find a shield a little larger than yours. You should be able to cut it to fit your oven using the old one for a pattern. The rivets shouldn't be a problem as Whirlpool, GE, and Maytag all use similar plastic rivets to secure the shields.
Hope this helps.
Thanks, Mike

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or a friend 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: http://tinyurl.com/yzjozk

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

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: I have a JVM1630WB GE Spacemaker microvwave oven.

It's almost certainly a shorted high voltage rectifier diode or a failed magnetron.

We have the service / repair manual for this model and have uploaded it to our site here for free download to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

Here are some handy links you or someone you know can use for test help:

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

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.

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.



You can also find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

If it's within the magnetron portion of the warranty (for this model it's 10 years from the date on the tag inside the unit) but out of the original full warranty (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.

G.E. they will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.

If it is not within the magnetron warranty, you can find helpful exploded view diagrams and order parts by entering your full model number here.

Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

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.
