OK: We have a freak. She does a fine job.
Sensor number for a N/O 215 degree single pole #8 MB sensor?
I can get that worked out and thanks for the education.

What is orb?

You looking for fan cycle switch? Most all are NPT. Kit Masters has plenty to choose from. ECM should be used to cycle fan clutch solenoid.

 

I just need a sensor with a push on electrical connector and number #8 orb. Normally open and closes about 215 through 230 F.
Amberfeldt: I did not mean to hi jack your post. You have a lot of good information from the others and I would be checking that wiring.
Easy way? Some power probe type tools have special equipment for that. It is still not always easy.
A lot of problems can be solved without a lot of special equipment. It is easy to be overwhelmed at the sight of the forest. You just have to start one tree at a time.
Sorry I have no wiring diagrams for those models.
