Thank you for your reply and information sorry for lack of details. It is 2008 Heartland Bighorn model 3400RL. The AC is Dometic model 59516.331. I see 6 wires on the t stat, not phone style. The control box is 3107541009. Also furnace does not work. The furnace has a 20 amp fuse in the fuse box, but it’s not blown. One odd thing I noticed is when I put a new fuse in(which blows immediately) the CCI LP gas alarm beeps and the lights on it go out. Any help is greatly appreciated, thank you
The clicking is the 12 volt relay on the control board. Normal. ODD that the LP detector is on the 20 amp circuit for the AC. Most OEM's install the LP detector on a 5 amp fuse at the main control panel. The short could be in the LP detector wiring. Doug
