air levelling

[William Harrison]

 My aux compressor works but does not come on automatically after I level the coach and air pressure drops.  I have had 2 broken driver's side windshields resulting from the left front sagging on uneven ground.  I sent the  600 series controller back to HWH to be refurbished and took the coach to HWH service centers twice where they confirmed that the compressor works, just not automatically.
Ride level works.

Chuck,

There is a pressure switch just downstream of your air storage tank that is set, if I recall, to turn the aux compressor on when the pressure drops to around 85 psi, it then switches off the compressor when the pressure reaches around 130 psi. The switch could be mounted on the tray that holds the aux compressor or it could be mounted closer to the storage tank. Follow the compressor discharge line to find it. It could be a broken wire to the switch or it could be the switch itself is bad.
