Jack will not come up?

[Frappier]

My jacks are very slow moving down but now have problem getting one up. Any ideas?

Generically speaking, you can try wiping the shaft of the offending jack with wd40. Just to clean the shiny part. Wipe wd40 off after. Worked on my HWH system. Jacks were getting slower to retract and after 8 yrs one didn't. Started cleaning them more often after that. Get a owners manual for your system if possible. Call manufacturer. They will have quick fix answers at hand.

Yep, Try giving the shafts a good cleaning with WD40, making sure you wipe them off really good or else the WD40 will be a dirt magnet. It might take a couple cleanings if you haven't done it in the past. My HWH system is 14yrs. old and still works great. I do clean them a couple times a year, and I'm still surprised at the amount of gunk that will be on the cleaning rag even though the rams look clean & shiney.

You may have a bent jack. Just spent a ton of money to find out that I had one. Tough on solenoids

My rear ones are also slow. Wipe down with WD helps. I keep a length of rebar in the RV to pry them up when all else fails.

I keep a short 2X4 with a wedge cut on one end so it can be rocked and slid under a stubborn jack. Dirt does stick to them and an occasional wipe with WD40 or sometime Garage Door Track Cleaner and Lube will help.
