I have a CVHE-071 that wont transition the starter. I trouble shot the starter and found the D1 & D2 contacts not closing to send it in the delta mode. This is an '84 model machine. The contacts that are not closing are on the ''solid state compressor protection module'' from cutler hammer. The problem is that Trane no longer supports or sells these module. They told me I need a new starter panle and controller. Any one have a better solution ? The old Trane part # was RLY 765.
