here is the wire diagram
no voltage between com and 24 on cmc1, no valtage between com and out. there is a sensor in between the com and 24v on the borad, see pic (i pointed to it, it is attached to a copper tube.
what is shin?
wires both way look ok i got continuity from them
Anything else you think I can test or check out?
do you mean to bypass the switch?
bypass the switch got power at 24v terminal of the defrost board but not at the out
Is there any other switch that is wired into the defrost board like a low presure switch attached to suction line, that has to prove closed for defrost board to allow power out. If so, it would be marked something like LP IN and OUT. If so, that would have to also be closed (continuity) for the defrost board to send signal to contactors.
I don't see them. I include two pictures for the board
thanks a lot
just wondering if any expert has some thoughts on my issue.
I am still stuck here, any update?
