After setting the furance thermostat on our Cougar 318 SAB, I hear multiple relay clicks from the roof mounted AC unit, as the furance fires off. The RV Tech says this relay makes sure the AC is off and provides power to the furance gas valve. The problem that I have is, that I've had this unit to the repair shop twice now, once I think they danced and chanted under the AC unit, (no results) and the second time they said they replaced the board that the relay is mounted to. I haven't had time to physcially check to see if there's evidence of replacement, but it still clicks. The AC is a Dometric unit and I was on a repair site that another peson was complaining about the same problem. Has anyone had this problem with their furnance, AC or relay?
