SOURCE: jenn-air microwave JMC 7000 ADB has no power
I have a different Jenn-Air built in microwave & oven combination but I'm sure my solution will work for you as well.
My microwave was plugged into an outlet located on the top of the oven. This outlet has a "circuit breaker" that tripped while we were using the self cleaning feature on the oven. You just need to reset the breaker button right next to the wall oven outlet. Why it tripped is a mystery since the microwave was not in use at the time. Bad design.
Of course, getting to the reset button is your only challenge. You need to pull the microwave and oven out of the wall/cabinetry in order to get to it. The unit is heavy so you will need help. Or, call a certified repairman and they should be able to do this for you in 30 minutes or less so the service call should not run you more than @$85 if it is no longer under warranty.
I would also suggest you contact Jenn-Air to complain about this issue and seek reimbursement from them if necessary.
SOURCE: My GE Built-in microwave model JVM1870 appears to have died
A microwave can be dead
for many reasons.
It
may be the fuse, which is usually located behind the grille, on the
floor of the oven behind the control panel, between the door switches,
or on the filter board near where the cord comes into the unit.
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.
You can download GE
owner's manuals and installation instructions here to make that easier.
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.
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 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.
You can usually find
helpful exploded view diagrams and order parts by entering your full
model number here.

SOURCE: dead microwave
There are replacable fuses inside. Taking the microwave apart requires removal of a lot of screws and the cover that can be rather bulky. make sure it's unplugged and safe before you begin. you can get replacement fuses at radio shack, ect. be sure to buy the same type and amperage. if the blow a second time there may be other issues.

yes it s a large ceramic fuse and you have to remove the outer cover to access this. it will be on the top of the M/wave frame either front L or front right. Cost is about $40.00

There is a high voltage fuse in the unit attatched to the high voltage capacitor, it is the most common problem for microwaves not working. Also check the protective diode,the high voltage capacitor as well as the transformer if the fuse is ok. Good Luck.
