Thanks for the info. I am working with reputable companies, but need to find the parts. Good advice. I did finally find some part numbers on a coil.Probably QW 6-60 I 23W 537 IV. Number on Otis tage 537-IV-10, this was staring us right in the face. Part is 1 11/16 long, outside 1 7/8, inside is hard to determine. Went to www.seeinc.com, some selection but can't sinc the part #s. Controller type is 1-SOB, not SOB. Couldn't get good pictures from the Otis tage, yet.

Thanks for your time.
