In several of the microwaves I have found schematics inside in envelopes. They have really helped. I found out from Peter Terren that the small metal sensors are heat sensors like I thought. Each oven has about 3 or 4 of them. Some also have a sensor with a little screen on the end that look like they are moisture sensors.

I'm pretty sure that I have everything identified now. My arm is killing me. It's been quite a few years since I turned this many screws!!! One thing that is irritating me is that only one of the transformers is labeled with the voltage ratings. Some say they run off 120 VAC at 60 Hz but not the output. The labeled one is labeled 4000 V. All but one of the caps I've removed are rates between .91 and .98 mF. The other one is 1.0 mF. I was hoping for higher ratings.

Think Positive
