Brian,
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.
