Jack slips down while driving

My Kwikee system, do not have springs inside the cylinder.
They are controlled by 2 valves, extending / Retracting valves.

Now, my system, will drop when I hit a big bump, however everytime I get out to look, all I see is about a 1/2 drop on one. Fluid is good, no leaks. Yet all I need to do when we stop, extend and retract all. No valves are leaking, cylinder look good. Now I have been living like this for over a year. Until it happens alot. I am living with it. Then I will troubleshoot the system.

Anyway, you are correct until he responds we are in a holding pattern

Valves can leak INTERNALLY. Causing loss of pressure and that means a Jack will drop. You need to determine if more than 1 jack drops. If so and no external leaks, I would look at the Valve system. Also, do the Bleed procedure outlined in the Kwikee manual. With Power down and Power up, a LOSS of pressure is the ONLY cause of a jack dropping down. On your system, do you have the electric magnetic switch for down on each jack? Most Kwikee systems do. Doug
