Hydralic leveler won't go down

[Medicine_Man1]

My right rear hydraulic leveler won't go down. Jack it down and it will go back up. Any suggestions.

Well, State what brand and model jack system you have. What you posted makes NO SENSE. What switch? Doug

We used a bottle jack to push it down while the switch was on. Once down it stayed down. It went up as soon as the switch was pushed.

I think he means jack will extend in the down position but will not stay that way.

If that is the case, my two front Jacks or levelers did the same thing and I had to get them repacked.

spring return or power down power up

most likely problem, the valve for jack is NOT opening

could be a bad relay in the control, bad control board, or bad hydraulic valve/coil

manually 'forcing it down', either spring tension or internal vacuum is going to pull it back up
it needs hyd pressure to hold it down

What brand/model is your leveling system?
