Hadley SAMS indicator never stops blinking green
I have a 2006 Tiffin Zephyr. It's equipped with a Hadley SAMS air leveling system and also a HWH jack leveling system. Recently when I try to air level I press "SLS" then press "SET". This should normally start the air leveling sequence. Both side to side and front to back indicators blink green, meaning it is capable of leveling at the current location. The side to side will soon switch to constant green but the front to back continues to blink green. I've waited as long as 3 minutes and still blinking.
Any advice or suggestions appreciated.
