Hwh hydraulic jack sticks down.

I am a newbie and I have a problem. My left front jack wont raise up on its own. I switched the hydraulic lines , left front with left rear. The problem moved to the left rear. Would this indicate a solenoid problem ? I noticed that the solenoid for the left front was a lot hotter than the rest . Any help will certainly be appreciated.

solenoid has a release valve on it if it is a small one you use the cap from the tank and back the little nut on the end 3 turns to open the valve. If it has the large solenoid it has a t handle on the end and you turn it till it stops to open the valve. You can turn the little nut on the small vale too far so do not got past 3.5 turns this is from memory so someone may correct me but pretty sure i am close enough to open the valve.

Did you manually release the pressure with the nut the previous poster was talking about. IF you did that and the jack went up then it sounds like a solenoid problem. You can either hook the lines back up normally. TAke the solenoid off the left rear and swap with the left front solenoid and see if the problem moves again. Or you can buy a new solenoid and not have to take the time to swap them. Depends on how much you value the time it takes to swap and then replace versus the cost of a new solenoid.

Sorry you're here with problems.
Sounds like you doing the right things for proper diagnosis , and defective solenoid is a possibility.
Do you have the manual for your system ?

I switched the solenoids and the problem followed the solenoid. So I am assuming that it is the solenoid. Now where should I start looking to find a replacement ?

if you remove the solenoid, check the opening for debris. there may be part of the seal left in the opening. whenever you remove a solenoid, and move it to another location, carefully inspect the seal. if it is damaged, br sure to replace it. if you dont, it is very likely to develop a leak.
