the outdoor fan was not running and the only way the ornge is energized is the t- stat or outdoor board..I replacd the defrost board because it would not test defrost.

Some of them won't go in to defrost if the defrost sensor is bad.
just had the york people here today hope the problem is resolved. The only thing wefound was the way the humid was hooked up, rewired the unit with a current sensing relay and the home owners wonted the same t-state that thay put on. So thay got a honeywell with a york name. Now I hope I dont see them till there PM.thanks for all the help
