SOURCE: GE SpaceMaker Microwave suddenly stops while heating
I had same problem last week. My GE JVM1650 Spacemaker stopped after a few seconds of heating. Owned 16 months, manufactured Jan 2005. It was the magnetron, which was replaced yesterday. The magnetron has a 10-year warranty, but I had to pay $161.00 for labor by a GE technician. The call-out fee was waived at my request. I don't know what that amount would have been, but I can't believe the $161.00 for what was about 1/2 hour labor once diagnosed. Good Luck!

This should be an easy fix.
This
is usually caused by either a bad door switch or a loose door switch
mount.
Door switch
or mount trouble is usually caused by slamming the door or by opening
the
door while it's cooking without hitting the Stop pad first.
There are
plastic mounts inside the microwave which hold the door switches and
onto which the door latches lock when you close the door.
The screws on these
mounts may be loose. If they get too loose, the switches will not be
activated properly.
Sometimes it's
a broken tab on the switch holder, allowing the switch to rotate just
out of position. This tab
can be hard to see, since it is under the
bottom edge of the switch.

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.
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.
If you only need a
switch, you can order a universal type here for $5 postpaid.
If you think the problem
is on the control panel, we repair these nationwide by mail
for $39.95 postpaid in most cases.

A microwave can be dead
for many reasons.
It
may be the fuse, which is usually located behind the grille or on the
floor of the oven behind the control panel or between the door switches.
If
the fuse is good, it may be an open thermostat or thermal cutout (TCO)
/ thermal fuse on or near the magnetron or on top of the cavity / body
of the oven.
If it goes dead for a
while during or after cooking
then comes back on, the magnetron is probably overheating and causing
the magnetron thermostat to open.
Then when it cools, it
closes the circuit and allows power through again.
When
checking TCOs or thermostats, if it has a hood fan thermostat,
that should read
open, as opposed to the others, which should read closed.
If the cavity thermostat
needs to be checked or replaced you'll need to pull the oven from the
wall, in which case you can download GE
owner's manuals and installation instructions here.
If it went dead almost
immediately after pressing the Start pad, that's usually a shorted
high-voltage capacitor.
If it went dead a few
seconds after pressing the Start pad, that's usually a failing
high-voltage transformer.
If
it goes dead or blows the breaker (or GFI) when you plug it in or open
or close
the door, then there's a problem with a door switch or door switch
mount.
If it's intermittent or
random, it may be a bad
connection, usually on the control board or a loose fuse holder, or
even an intermittent fuse.
You should do a
continuity test on
the fuse while it's in the holder (with the microwave unplugged, of
course) then turn the fuse by hand or take it out and put it back in,
then test it again.
If you remove the fuse,
then press the meter
leads against the ends, it can allow internal contact to be made and
make a bad fuse appear to be good.
There
should 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.
You can usually find
helpful exploded view diagrams by entering your full
model number here. Once you have the part numbers, though, I would suggest ordering parts here at a much lower cost.

I have the same issue and the same unit. I wonder if there's a recall...
SOURCE: GE Spacemaker microwave JVM140G just stopped
NO internal fuse. It is most likely, the magnetron, and or High power diode. As related In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.
