Trouble shooting resulted in finding relays the most likely source of the problem. Pulled Relay 8 & 9 both stop the fan when unplugged. Fan did not stop when I disconnected spade connectors at the drier unit.

I'll check for part numbers. Looking at one of the on-line catalogs, one relay cost $32, but another for the a/c compressor was $125. Hopefully, all I need is the two for $32 ea.

Thanks for all the help with this. Alex
