Hi Jerry, I may take you up on those components, as I mentioned the system just decided to stop working a couple of days ago, and after reading all these posts I started calling it the SMC system , but after looking at the controller today , it is actually an IDS system, I was going to call Beaver Coach tomorrow and ask for some advice. The system was working perfectly, and then nothing. The control pad has power, it shows all up, and if you hit the retract button, you can hear the pump. But nothing happens when you hit the auto button, or the semi button. It does not even dump the air, and the air dump toggle on the console does not dump the air either. Ahhhhhrrrrg, what next? The day before water leaked into the electrical bay from a hole someone drilled for a tire pressure monitoring system, shorted out the connectors on the smart wheel controller, which I thought, no big deal. I'll just clean them up and spray them with WD-40 and that will fix it, no such luck. Downloaded the manual and ran through their diagnostics, and it says replace the controller. Awesome what's that worth?
