Thanks for looking guys. The Bama site schematic is what I have and it
doesn't detail the 180 sec timer circuit and Omega wants us to send it
in for repair. I guess I'll try reverse engineering a diagram of it and
then troubleshoot the thing. I hate "shotgunning" parts in something
that needs a small .25 watt resistor. It is so easy to burn a circuit
board or destroy a good part and still not fix the trouble. I have a
feeling there were several version of this thing.
Thanks again
