Just FYI - following some links I did locate a discussion about
locating the thyristor/thermistor (whatever) located near the control
board mounted in the uppor door. I did remove the item (described as
the silver thing mounted on the white plastic mount with the two
connector tabs on it). I don't see any evidence of overheating,
smell, etc. Using a VM meter this shows an open circuit. Is this
correct? Shouldn't it be normally closed? Any other way to test
this? Or is this the suspect failure?

Just very eager to know!!! Thanks
