I've replaced my rv comfort zc thermostat with a brand new one and it is still reading zone 1 41 degrees and we just can't get it to move off. The only thing is when we take out the fuse and replace it ,it goes to 72 and jumps to 41 . We've checked the control box in the a/c unit and it has a green light on so that's working. We've tried anything and everything we can think of. Any more ideas out there ?? Thanks so much
