It's very cold this morning and I tried to retract the slides getting ready to travel and nothing. In the bedroom, pressed the retract button and the slide slooooowwwly moved in. Then my finger slipped off the button and it stopped. Pressed 'Retract' again and, nothing. No sounds, no movement. Tried extending. No movement. Went to the living room and tried the big slide, still nothing.This happened a couple days ago, when it first got down to 28F. The next morning the slides wouldn't work. Waited until it warmed up a bit and everything worked on the slides again.So my question: Do the '02 HWH wall slides have an issue with the cold? Or should I look for a defective part?Thanks. I'm hoping I can leave today at 11 am. With the slides in.

The HWH on my 06 Itasca does slow down when we operate the slides in the cold. We never- never extend or retract the slides unless the engine is running and the batteries are showing 13.+ volts. HWH has told us the system only requires 9.7 volts, but Winnabego told us to run the engine. Experience has shown us to follow Winnebago instructions. Check the fluid level,

Cold does not affect the operation of the HWH slide. Next time it happens operate the Jacks. IF the jacks operate, then you have an electrical problem with the slide control side. IF they do NOT work, you have an issue with the electric battery solenoids on the jack pump(first guess). Doug

A hydraulic pump with atf fluid, should work at all temperatures you can camp inBut a tracked slide with the wrong grease can get very stiff when cold Can you normally hear the pump? Or notI never hear the pump on the Safari, so it would be difficult if i had to diagnose hydraulic problemsIt would take at least two people, one to go outside and listen the for the pump, one inside to push the button

Waited this morning until the temps got up to 50F and the slides started working again. I check the battery voltages as I passed the panel in the hallway just after retracting the small bedroom slide (it's a clothes closet) and they read 13.7 Volt house, and 12.8 Volt chassis. I do have a Trik-L-Start installed.jdealcpa: Front slide moved fine after it warmed up, although it seemed a little slow. RV jacks were down, RV nice and level, no bad sounds while it retracted. I haven't thought about starting the engine first, I'll try that tomorrow morning bright and cold. dougrainer: Such a great test. Why didn't I think of that? I did not check the jacks when the slides were not working as I just didn't think of it. I will if they don't work tomorrow.I'm now settled in at a nearby RV park for 4 days, which should be 28F again tomorrow morning. I'll test using all the suggestions.Mr. Wizard - I'm hard of hearing, but normally I think I can hear the pump OK but only in the LR (though it may just be incidental noises associated with the slide rubbers). In the BR, can't hear it at all. Even when the slide is moving. Don't have anyone to listen for me, so I try to not use hearing as a guide. I just watch carefully.

Got up this morning at 6 to run these tests, outside temp was 48F. Slides: NO OPERATION.Checked voltage on batts - 13.4, 13.0Tested Jacks - Jacks work OKListened carefully in the LR - Could not hear pump motor or any solenoids clacking.Started Engine - Slides still not operating.So it's looking like an electrical problem for sure. Later today I'll try to check some electrical connectors down on the hydraulic assembly.
