My microwave counts down but the magnetron is not turning on... At first I thought it was the touch pad, but I tried the defrost and got the same count down without the microwave relly turning on/engaging.

Is it the touchpad or is the unit's microwave emitter shot?

Any ideas would be helpful. It's a hand-me-down so I do not have a manual or any clue....

Is it the touchpad or after 16 years do the microwave units just STOP!!!! Confused

The touch pad and the controller appear to work properly.
You should remove the cover of the unit and check the following items:
- Fuse (6Amps or more)
- wires and connections may be faulty because of the high current and heat
- the relay (or triac) which controls the power transformer
- the power transformer - all windings
If all items above look good, then the magnetron must be defective and the unit doesn't worth to be repaired.

Please be careful: ALL MEASUREMENTS SHOULD BE MADE WITH A OHMMETTER AND WITH THE UNIT UNPLUGGED. DANGEROUS HIGH VOLTAGE ARE INSIDE.
