Mr. Jim typed:
"Is that the aluminum housing servo I sold you a while back?"
Yes it is. It served me well last summer. What do you reckon Murphy would
charge for a rebuild?
"What happens when the blower dies and you push defrost? Defrost should
bypass the servo and put the blower to full speed using a relay. If the
blower
only runs in defrost, it could be a bad servo."
After it fails and I mash the defrost, the blower comes back to life and I
get loads of air out the defrost vents and whispers of air everywhere else.
Somewhere I have a pushbutton assembly I picked up somewhere. Perhaps I'll
swap it out and see what happens.
I suppose I need to devise a systematic troubleshooting methodology for this
and get it right this year.
