GE Adora DVM1850 Microwave Oven Questions & Answers
Control pad is dead
Dead, meaning no
display, no light when you open the door and no beeps when you press a
pad on the keypad?
Is the outlet working?
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.
This model has a bottom TCO, a 20A fuse, a cavity TCO, and a magnetron (MGT) TCO.
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.
This would indicate a bad magnetron or a bad cooling fan.
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.
So don't let that fool
you.
To check some thermostats, you'll need to pull 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.
If it went dead almost
immediately after pressing the Start pad, that's usually a shorted
high-voltage capacitor.
If it went dead
several 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.
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.
You can find
helpful exploded view diagrams and order parts by entering your full
model number from the tag on the oven here.

Microwave does not heat
your magnatron tube (what heats the food) is out, if it is not still in warranty it will run 200-300 to fix, might be better to replace sorry
Not heating
most likly it is the mag and the diode. it should be covered for ten years after you bought the unit so check into that. you will have to pay a ge authorize servicer to replace it though but parts should be covered and still cheaper than a new microwave
It went totally blank after
Hi,
A possible problem on the heating element or only in he fuse. Better check and take it for repair.
Hope this helps
Microwave, adora, stopped heating
Hi and welcome to FixYa,
Almost always, on most microwave including GE Adora, no heat with all else working indicates a problem with the magnetron. Since the magnetron produces high RF energy and operates on high voltage, it would be to your advantage to seek the services of a qualified professional.
If on the other hand, the fault of no heat is coupled with no display, error messages, door not locking, no light, then it would be possible for a DIY (do-it-yourself) repair. All that is required is a bit of familiarity with electronic components and circuitry, the use of a DVM/VOM of course safe working practices when repairing electrically powered devices.
Pls post back any other symptoms or indicators other than 'no heat'.
Good luck and thank you for using FixYa.
