Thanks, Doug! I sort of figured that the power to the compressor control board was the issue, but not sure how to fix it (obviously).

Connecting BOTH blue wires to the 12 volt DC+ turns on the fan, but not the compressor. It is possible that the fuse on the control board is blown, as dear husband isn't anxious to climb on to the blistering hot roof to check right now. Would a blown fuse on the control board keep the entire AC unit from running, or just the compressor?
