Power gear levelers have 3 major modules not counting the jacks
One is the control panel
One is the pump/valve assembly
And the one you need to find is the sensor assembly.. I can not describe it to you but it has adjustments on it. And it is likely under the coach (But no need for it to be there.
Using a pair of carpenter's levels, or one of those square or round bubble levels and the manual overrides on your panel LEVEL the RV.
Then find that box (Well find it first) and adjust till it believes it is level.
Or you can have a dealer do this. Should take less than one hour (minimum billing at most dealers) if they do it.
One other thing about power gear jacks, in case you have yet to come across.
The "Jacks down" sensor on Power gear hydraulics is a float valve in the fluid tank, If the tank is low on fluid, (Dextron III or Mercron something) then it thinks the jacks are down.
IN August, when temps are in the 100+ range, the fluid expands due to heat much faster than the steel tank, the result, overflow.
Then comes January when the reverse happens, The result, LOW JACK ALARM.
The fix: Add fluid,, Read the manual if you want to do it right,,, usually do not do it that way.
