Operating the Hydraulic Slide in Cold Weather

[Bill C]

Has anyone experienced any issues Operating the Hydraulic Slide in Cold Weather? 

We we closing up the RV because we were leaving for a couple weeks. As I tried to bring in the Living room slide the hydraulic motor ran but no movement on the slide. I let off on the switch and the slide moved and inch or so inward. I had to repeat this process several times until the slide was all the way in.

The temp outside was around 26-30 deg F, I can't remember exactly. I did not have time to check the hydraulic fluid level before leaving. BTW, where is it located, near the pump (under passenger seat/front steps area).

As I understand it, the fluid used is like Dexron III AT fluid, correct?

Anyone else experience this?

Thanks in Advance,

Bill

I have not had any problems in cold temps with my slide.

I've had no issues with temp.

Almost sounds like you have a hyd pump solenoid issue.

[Bill C]

The solenoid is fairly new and I can hear the pump running so I don’t think it’s a solenoid. I guess it could be low on fluid. I’ll check that when I get back up there.

Yeah, definitely the first place to start.

Also, your hyd pump will have more than one solenoid valve. The number will depend on how many slides it has to move!

If you decide to service the system at some point, it’s a good time to change the system fluid, if you do this consider going to TranSynd 668, same fluid as you might/should have in the transmission and reduces the number of fluids that you need to carry in your vehicle. Jmo.
