SOURCE: microwave does not heat
What could cause this problem coud be a bad door switch, a bad HI Voltage capacitor, a bad power transformer, a bad Rectifier, a bad magnatron,or a bad circuit control board. Any one of these repairs could run from 65 to fix, all the way up to 200 bucks. You are probablt right, its time to buy a newer type with more lights, bells, and whistles. Good Luck
SOURCE: Microwave runs, stops and counts down, starts again, etc.
Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP button) is the primary cause of door switch failure. You can visit my Web site at _ or e-mail at _ if you'd like more in information on diagnosing and repairing this problem.

All the parts you mention are very inexpensive, but yours does not have a triac.
It could be the cook relay, but it's more likely to be a switch.
Looking at the schematic, it's probably a bad primary interlock (upper door switch) or maybe its mount is bad.
Even though a door
switch clicks, it may still be bad inside.
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.
If you have a broken mount, it's usually more economical and
safer to just add a dab or two of hot glue to the mount to secure the
switch. Let it cool for about 30 minutes before using.

There may also be a "mini-manual" hidden inside the unit behind the control
panel or elsewhere, which is very
helpful when troubleshooting & testing.

If you only need a
switch, you can order a universal type here for $5 postpaid.

Ok just figured this out! It is a problem with the alignment on the lower door switch. I took the cabinet off and lifted up on the door switch slightly and voila! It works. You could probably fix this without taking it apart, just lift up on the door ever so slightly. I hope this works for you.

HI, when the Magnetron becomes unstable, the microwave will not heat anything. simply replace the Magnetron. This device creates the heating action and it is damaged and not functional at this time.
