Lowering front jacks causes hyd. slides to extend
When raising the front of the trailer to unhitch, the front jacks took a partial load and stopped. The hydraulic pump didn't change pitch so I kept going until I heard something creaking. I walked around to the curb side and the dining room slide had extended. When I retracted the jacks, the slide also retracted. I closed the manuals valves for the slides and the front jacks worked normally. When operating the slides from the inside control, they extend and retract normally.
Given this information, I assume the solenoid operated valve is defective. It appears the solenoid is operating normally but the valve is not sealing in the "off" position. Before I tear into this, does anyone have experience with removing/servicing these valve assemblies? I suspect a torn O-ring, but really don't know the details of these particular valves.
I would appreciate any insight.
Safe Travels.

Had that issue and in my case the solenoid valve manual override set screw on the top of the valve for the slides was not completely closed. I forget where it is but Lippert on their website has a procedure that shows the valve. I adjusted that with an Allen key and all is good now.

Thank you for the response, Elkaholic. I checked the manual override and it is properly closed. Problem persists. I'll pull the cartridge valve and check the O-rings.
