As subject, jack is slow to none when operating. Just got this unit, 2014 PC with 325 model HWH. THERE WAS a 74”x24” mirror glued to a wall partition until the first time I tried leveling. Frame tweaked and shattered the mirror. I’ve read the manual and watched several YouTube vids before I started and understood they are (supposed)to work in pairs. Now I know to look before fully extended, and found the right front, SOMETIMES ***** down but will not extend. The red light for that jack illuminates right away. When partially cocked(the left is fully vertical) I can tap the jack and it will move down a little. So, bound some where? Weak hydro to that cylinder? Retract works fine, but that is all springs isn’t it. So where to start? Do have a call into HWH but haven’t heard back yet.

Don't know if this will help. I'm guessing a "2014 PC" is a Phoenix Cruiser, and not a laptop. https://www.phoenixusarv.com/community/index.php?topic=1107.0

325 JUST MEANS THE JACK CONTROL SYSTEM. HWH Jacks can be 2 types. KICK DOWN and STRAIGHT ACTING. Kick Down means they swing DOWN vertical when pressure is supplied and then extend and when retracting, they retract and once clear of the ground, will swing horizontal and fully retract. WHICH type you have will depend on the cause and help you require. DougThis is the Service manual for a Straight 325 system.https://www.hwhcorp.com/ml37640.pdf

The First thing you do, is open up the manual release nut/spring loaded 2 center solenoids on the pump manifold. Those are the front Jack solenoids. You then activate the pump. IF the jacks both go DOWN(extend) then you know the Jack and HYD lines are good and not pinched. Look at the Manual I linked and it will show which solenoid is the RF. Close the solenoids you just opened. SWAP the 2 -2 wire solenoid pigtails connections on those 2 solenoids. IF the RF now extends and the left does NOT, you have a 12 volt power problem from the Main HWH control board, probably a blown RF solenoid fuse. If so, replace that solenoid fuse. BUT if a solenoid fuse is blown, odds are it has a internal short and will blow the fuse again in the future. So, if this fixes the problem and it happens again(blown fuse) replace the solenoid. IF the rf jack does NOT extend when you swap the pigtails, the solenoid is bad. Doug

Op. Thanks Doug. These swing down 90*. Tornadoes in the forecast so might be a day before I can try your suggestions.

Have you cleaned the control rod on the jack?Make sure it is straightMake sure the small bearing on top is free to spin.
