I did switch the 110v on the relay and the compressor did not run. Will it run with the door open? Door switch is good and I tried it with the door open and closed. I will recheck the 24v side, but, I don't think I had any voltage there. Those are two white wires, I believe. I could check continuity if I knew where the other end is. I don't want to damage the board so I didn't get too adventurous.
