I have a Frigidaire Microwave convection oven. Model number LEVM30FE. When try to use the basic microwave function I get an error code "E-21".

This
is a problem in one of the damper-related components, most likely the
switch, but it may also be the motor or the damper door.
The
damper is a door inside that opens or closes depending on cooking mode.
If the controller senses that the door is not in the right position, it
will shut down the cook cycle.
Sharp models stop after
59 seconds.
See the attached sample
photo for a typical damper assembly.
Info on ordering Sharp
UK parts / spares is here.

If the fan and light are on when it's running, but the oven is not heating, it may be a bad door switch. We have important safety information and a help file to test and replace door switches and you can find it by searching on Yahoo.com (not Google) for microwave circuit repair It may also be a bad connection at the magnetron or another problem, but please look over this information first then let us know what you find out.

Since the light comes on and the turntable rotates, I would suspect a bad magnetron, a loose connection at the magnetron, a failed high voltage transformer, or shorted high voltage rectifier diode.
If it's less than one year old, it should be fully covered under warranty.I'd suggest contacting the manufacturer to get it fixed free.
Ifit's within the magnetron portion of the warranty (usually 5-9 years)but out of the original full warranty (usually 1 year), then yourmanufacturer will cover the part cost, but not the cost to visit you orthe labor charge to do the work.
If you or a friend want to work on it, please see these links first:http://www.microwavedisplay.com/safety.txt& http://www.microwavedisplay.com/disassembly.txt
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

Thereshould also be a "mini-manual" hidden inside the unit behind thecontrol panel or hidden on the left side behind the grille, which isvery helpful when troubleshooting & testing.

You probably have a bad thermistor.
You can usually find
helpful exploded view diagrams and order parts by entering your full
model number here.
(At that site, that part is misspelled as "thermister" for your model).
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.
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.
Accessing some components for testing 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.
