So you are happy with the way yours works? Engages and disengages when it should? Curious because I have read about some units being too aggressive (for lack of a better word), locking up too early and staying locked for too long, creating power loss and extra noise.
No complaints from me. Works as expected. Seems just a bit tighter than my (probably still working) original, as you'd probably think it should.

Seems to tighten up an appropriate amount for the heat load.
