Chester,
As you have figured out...the logic for the compressors comes from the thermostat. It could be a faulty thermostat or broken wires or something wrong with the compressor itself. There are also some relays on the board that could be bad.
As a way to split the problem, can you check the wires from the thermostat (where they attach to board)? I'm going to guess that the control voltage is 12VDC. I would just pull the control wire connector and use a paperclip to probe the end of connector.
Cheers!
