HWH slide/leveling system.issues with extend/retract.HELP
I have a class A 1998 Thor Residency it has HWH 310 series leveling/extension system.
it has 4 solenoids for the leveling system one for each jack
it has 2 solenoids for slide, retract and extend
all 6 solenoids are the same
here is the issue.....leveling system works perfect
will not extend or retract, pump does run.
if i relieve the pressure on the extend solenoid push switch it will extend.
to retract i close the extend solenoid relieve pressure on the retract solenoid push switch goes in.
today i switched 2 leveling solenoids with the 2 slide solenoids to see if the issue would follow.
leveling works great...slide still works the same.
i also removed the manifold check valve and it looked fine
Im running out of ideas.....
any advice would be greatly appreciated............
