"Jacks down" lights come on - excessive temps ?
« on: August 18, 2010, 01:45:32 PM »
I have been relatively pleased with almost all aspects of this MH but after returning from Yellowstone trip last week, have in Kings campers for a number of warranty item repairs / replacements...
Main item is that while driving in Yellowstone and on way back, the "Jacks down" light on dash and the leveling panel strts flashing and beeping -- scary while driving thru narrow tight roads..especially once when I believe they actually started to go down..... first couple times, I pulled over asap, turned on leveling system, start jacks down, put jacks back up, shut off system, good for another 3-4 hours..... after the third time, I tried turning on the system while continuing to drive on, pressed on emergency brake lightly, released it and lift it's brake pedal arm firmly with foot, pressed the jacks up switch repeatedly and everything seemed to reset ?... until the next time a couple hours later again......
The dealer is telling me that they relayed this info to Winnebago and were told that all swithes and panel are fine - this is not uncommon when coach is being operated in high heat conditions... just need to reset like I did and not worry about it..... Dealer further tells me that some Tiffin coaches have same problem and on those, the driver just needs to push the "store" switch and all is OK...
Question... Is this correct ? ... Anyone actually have this happen ??
The ONLY thing that makes me MAYBE believe this is that it was the hottest I've ever had this coach exposed to .. but it doesn't seem logical that this happens to both Winnegabo's with this system and similiarly with Tiffin coaches ? 
New antenna cable is apparently on order for the outside radio - apparently has a short in it somewhere...
Both the front fenders have been "reglued" back on... I was astonished to learn these are actually glued to little rubber blocks which are then screwed to frame with plastic screws.. each one came loose on way out and truck drivers motioned for us to pull over ... wasn't noticeable to us but fender flops away in the wind when driving... fortunately, nothing apparently bent out of shape - must have caught it early - happened to have bungi cords so drove around with cords holding my fenders in place...
Hopefully the drivers window will now work well, one broken compartment latch replaced. some door squeaks hopefully quietedby tightening somethings inside, and finally,
The lock down latch on the large awning arm apparently let loose once while we were in very high winds on top of mountain pass in a rainstorm... the spring loaded corregated metal thing that curls around the awning when retracted became "open" and boy did it rattle ... sounded like a dozen people banging on the roof with metal rods...  got soaked and tired hanging unto whatever was there while on roof in the rail putting bugi cords on both arms and wrapping duct tape on the metal shield so it could be driven rest of vacation...... not sure yet what they did to correct this from happening again....should find out Fri after radio cable is replaced...
Had windshield crack repaired Friday.... thanks to rock thrown in central yellowstone off another vehicle..
Crack is low and not in line of sight so hopefully the "glue job" repair will last fine..

This is now embarrasing and untimely because all my manuals, supplemental manuals, and briefcase with all MH info is in the MH which is still at dealers until I get it back on Fri...
I know they are hydraulic with auto leveling ( or can be done manual) but I don't have the Brand/model/specs on them....
Having just been told that it's common for this to occurr, I though I'd get some experience input on it before I go to pick up the MH on Fri and get told again to not worry about it... may also contact Winnebago tech support unless a number of folks say it's common for this to happen in high heat usage....

Have never heard of heat being a problem - how hot was it?. While it has been hot everywhere this summer, in other years coaches are often driven in high heat. Most anywhere in the southern US between May and September and much of the midwest in summer is going to be in the 95-110 degree range and most RVs plow through it ok.

Even if it is true, I find it hard to accept that as an excuse. The jacks ought to work right in those temperatures. They aren't all that uncommon.

Exactly my thoughts.. I find it hard to believe that it's common for the "jacks down" lights, the "emergency brake on" light, and the jacks on lights to come on unexpectedly while driving and start flashing because of heat ( believe last week out there was 90-97 each day... and over 100 in sun but ?....
I did find that the jacks on the MH are the more advanced automatic leveling model of the "Kwikee" Brand ...

I do recall in the HWH manual for my 06' Meridian. They did state that "thermal expansion" of the fluid could cause the jack warning light to go off while driving. While it never happened to me, the cure was simply to turn on the system and hit store.  There must have been an issue in the past for them to include that in their documentation.

After slowly climbing the grade to the Eisenhower Tunnel at the Continental Divide on a hot day a month or so ago, the jack alarm came on while I was in the tunnel.  I pulled over at first opportunity, noticed that one jack was down a few inches, and stored it.  A tech at HWH told me that the problem was simply thermal expansion due to the heat/grade, and not a bad solenoid or weak spring.  Hasn't happened since.

Aldo: is your rig a DP? I could see thermal expansion doing this especially with a puller putting engine and exhaust heat under the chassis but not being a problem with a pusher, just a thought.

I've experienced the jacks light coming on while driving on two different coaches (both Winnebagos). One was a gasser (02 Adventurer with HWH hydraulic jacks) and one a DP (10 Journey Express with Power Gear leveling system). In most recent instance, I was driving only about 4 miles from home to fuel up the night before a trip. It hasn't happened since and that's after 2500 miles of travels. Not something I fret over as I believe the jacks will not fully deploy without the parking brake being engaged and the coach in park or neutral.

I've heard the thermal expansion of the hydraulic fluid theory before too, but it has never happened to us traveling in very hot weather ...60k miles on this coach.  However, I did note one thing in your original post ... you said,
Quote
I pulled over asap, turned on leveling system, start jacks down, put jacks back up, shut off system, good for another 3-4 hours.....
   I don't know about other brands, but on the HWH computerized systems HWH has said to many of us that we should NEVER shut the system off manually ...and that if we do, and the jacks are not fully cycled, they can creep down while driving and set off the alarm just as you describe. The system will shut off on it's own when the retract cycle is complete, just as it does when the automatic extend cycle is complete.

You're correct... I stopped and did that twice on the first two times it happened but believe both first two times it was after we had been in campgraounds for an evening and the jacks had retracted in AM normally.... system had operated normal and automatically down for the previous evening and back up in AM... IF I recall correctly, it happened once each of those first two days.. then the third day was a longer one and it happened three times during that day but I didn't stop.. I set brake slightly, released it while driving and believe I also turned system on manually, hit "all up" a couple or few times, and the lights and alarm went off - for a couple / few hrs...
Heat theory Interesting because after arriving back in MN / WI I don't believe it happened on the last two days of driving -or - earlier this week during the 45 mi trip to dealer .... still don't believe something like that however should be allowed to happen ... has to be a corrective solution.... to prevent drivers heart attacks while friving on tight and steep roads if nothing else.... going to pursue with Kwikee if they'll respond...

I don't think Kwikee is the company to contact about your jacks.  They don't know jacks. :-X   HWH is who you want to contact concerning your jacks.

I think afchap hit the nail on the head here.  I recommended that same solution to another guy in here recently who had shut his HWH system off manually instead of letting it turn off automatically.   It sure solved that same problem for me.  So the bottom line is, if you shut your HWH system down manually, you should expect to see a "Jacks Down" light on in your future.  It's the only reason that I know of why the "Jacks Down" light comes on.

We had a similar problem many years ago on Tiffin MH with HWH jacks.  This happenened a few hundred miles down the road from campground.  Tiffin asked if we manually tyrned off jacks (starting engine does same thing) when green light came on..which we did.  They explained the green light only indicates that the jacks are above the minimum clearance for moving but have not fully retracted.  They said when we restarted MH to re-engage the stow function and let the controls turn off the system.  We have followed this procedure and have had no further problems.  In the fully retracted position the jacks apparently have room to creep if that is what happens.

We've operated the coach in over 110 degree weather with no HWH jack issues, and like all of the other responders, we always let ours cycle off automatically.

Jacks are Hydraulic cylinders Thermal expansion is usually minimal in cylinders this small, however a bit of air in the cylinder for whatever reason will increase the effect a lot. Sounds like to me that the Jacks were not fully stowed before you drove away and they extended a bit for whatever reason. Maybe there is air in one of  them.

I'll ask dealer about checking for air in them..
I did find a brochure on the MH from when I bought it new last year.. It shows the leveling jacks as "Kwikee  Level Best" automatic self leveling system...
I then found the Kwikee Products Company web site and they do show the same - and the panel is the one I have on the MH....
Printed off the manual ..
Directions for Retracting the Levelers and the third(last) step in the process states,,,
" When all leveler legs retract to the travel position, the red "ALL UP" LED will turn green, and the pump will shup off. You can now turn off the power switch and the vehicle is ready to travel"
Based on that, I'm thinking I have followed those directions and what's happening is not supposed to.....
These supposedly have a 5 year warranty so seems like Winnebago should end up honoring whatever correction is appropriate...
The Kwikee number listed in their most current manual for "Questions for the Kwikee service department at 1-800-736-9961"  is a NON-WORKING number.....
The number listed for the company is 541-942-3888......... so far after 6 tries, no one ever answers....

So far, the Winnebago tech folks have previously responded with reasonable information replies.. guess I'll try them on this issue also.....

Sorry WhiteEagle, I thought you had HWH jacks.  Kwikee does indeed make leveling jacks, I looked at them on their website.  The Kwikee Level Best brand are two-way hydraulic jacks which means the jack legs are raised and lifted hydraulically.  They can also move one jack at a time, versus only in pairs as HWH does.  They actually look like pretty nice jacks but nobody seems to know much about them.  Why don't they answer their phone?

Ignore all previous posts about HWH jacks then  :o

The Kwikee number ........ so far after 6 tries, no one ever answers....

This is a  common complaint about Kwikee going back for several months or maybe a year or more.  I think Kwikee's policy is now to only work directly with dealers and will not talk to the end-user.  Search the forum for Kwikee and you will have some interesting reading.

If I recall in the HWH manual it says that after you hit the store button and all the jack down lights go off, not to press the off button.  That way if there is any pressure increase while going down the road it will bleed off.  That sounds like what is occurring with pressing the store button multiple times.  Not familiar with the Kwikee brand but maybe a sensor is seeing a pressure increase and "thinking" a jack is extended.

Still working on it but Winnebago tech support came back quickly... with some good info at least..
Kwikee has now merged with Power Gear.  It is best to contact them directly at their email address of info@powergearus.com.
The leveling system warning lights are wires in a series.  When the lights go out the system is closed.  For the lights to come on while you are driving, the system is creating an open circuit.  We would tend to believe there is an intermittent problem with a bad connection or a leaking solenoid on a jack.
Suspect that's why Service line is not working and maybe why no one will answer their main phone.... Sorry example of customer service ......
I have sent Powergear the info by email and made a request for recommendations...
Have also called dealer that has my MH and asked that in the absence of anything firm between today / tomorrow, at least check all connections on the Kwikee level controller panel and the circuits where they can, the emergency brake switch, for something loose, and to check for air in hydraulic fluid, or one of them leaking.... they say they will....
Hopefully Powergear will come back with something...

Our 2008 Winnebago 39Z has had jacks down light come on. It has power gear system. The light would come on when we hit the brakes hard.
We found the light is turned off by a (probably float) switch in the reservoir tank, when all the fluid it returned. Ours had a dip stick which registered the oil level OK, so we called power gear. He said add 1/2 cup oil at a time till we no longer had the problem. We had to do that twice ( two 1/2 cups) & have not had a problem since.

Neal..
Thanks for that insight also.. good obvious think to look at and consider... hopefully dealer will do that tomorrow with what I've asked them to check .. but I'll make sure when I go to pick it up...
As all manuals etc are in the coach at the dealers, I don't have it to look up where the resevoir might be... your rig is step up and larger with Freightliner chassis and mine is the Ford chassis but based on the Kwickee control panel looking the same for all of the "Best level" anyomatic levelers, can you tell me where the resevoir is on yours - dipstick and fill tube ?
Unless the dipstick shows over full already, I might try adding a 1/2 cup or so if dealer finds nothing else..

Don't confuse HWH and Kwikee.  Kwikee is a complete hydraulic sytem up and down, no springs.  The manual says that after hitting the "ALL UP" button the system will stow the jacks and turn off on its own.  Don't press the off button, per the manual.

Thanks for the input..
The Kwikee manual states .. Quote..
 The Directions for RetractingLevelers ..
" When all leveler legs retract to the travel position, the red "ALL UP" LED will turn green, and the pump will shup off. You can now turn off the power switch and the vehicle is ready to travel"
Based on that, I'm thinking I have followed those directions and what's happening is not supposed to.....
Powergear has responded to an email with
"Hello,
 they way the Kwikee jacks detect that the jacks are down on striaght acting jacs are the proximity sensor on each jack. if the fluid starts to heat up between the valve and the jack it can move the rod down a little whitch then the sensor sees that and thinks the jacks are down. by stopping and retracting them takes the pressure off the valve and allows the fluid to return to the tank and the jack retracts. hwh has a valve that engerizes and allow the fluid to return also noted as the stow button." .........................
Based on what this Powergear rep states, it is a heat caused incident and requires pushing (in the case of the Kwikee Best Level case) the "All Up" on the panel when ever it happens...
I have sent a follow email question to Powergear asking if there's a remedy or it's uncorrectable...

From your last description, we must have different jack systems. Mine has spring return & no green lite when jacks are up. We also do not find Kwikee anywhere on the system.     
Our tank is located just behind the Kwikee door step, between the front wheel & the front of the coach. Remove one tread of the indoor step to reach the dipstick & filler plug on top.

Ok.. we have different systems... mine is a Kwikee Best Level fully automatic hydraulic system - Kwickee now part of Powergear....
I just got a follow up response from Powergear on the issue...
Quote..
"Hello,
best advice i can give is stopthe coach and turn the touchpad  on and retract the jacks. "

I picked up the MH from dealer today and spoke with two seemingly lnowledgable mechanics....
They had checked all connections, jacks - no leaks - etc... Both said that these Kwickee Best Level systems have been known to occassionally have the "thermal expansion" problem in extreme heat situations .. apparently can happen once / twice / a few times and then is known to  never happen again.... maybe I've now experienced that event... they say the system is fine, they checked out everything and doubt it will happen again.. if it does, just hit the "All Up" swith again and should reset the switches...One of the jacks apparently had this thermal expansion of the fluid between the "up switch and the chamber which forced it down to where it belives it actually wasn't all the way up ..... one comforting thing is that everyone there says there is no chance the jacks will actually come down unless I really and truely set the parking brake and then turn on the system and hit the auto level switch.... can't happen !! ??
I now know where the reservoir is and will check the level of fluid this weekend....they said it was fine...and system has no leaks...
Guess I'll wait and see if that issue has gone away by itself... Didn't happen for last 3 days of driving and last approx 1000 mi.... My cursing at it on the fourth or fifth time it happened must have fixed it.....
Besides that issue... All warranty repairs and adjustments done very well by Kings Camper in Wausau WI - all 9 items done on warranty and my cost in total for these was Zero.....
Also learned that Van Boxtel (Green Bay WI) has apparently discontinued sales of Class A motorhomes and is only dealing in trailers and Class C's ..........
Pleased I had all work done at Kings and established relationship with several there... good folks....

... My cursing at it on the fourth or fifth time it happened must have fixed it.....

I've tried that before with varying results  ::)  Thanks for the report back and glad you had a good dealer experience!

I confirmed that the dealer mechanics had tallked to the Powergear techs so that's likely why their diagnosis opinions and responses were same... hoping that's the correct diagnosis and it won't resurface....
Before leaving the dealership, I had mechanic show me where the reservoir was for the jacks hydraulic fluid  ... out of ongoing curiosity yesterday, I checked this fluid level and it was in fact low..... cap was dusty - I believe it had not been removed or level apparently checked ? Not sure what to think of that......
I added almost 8 ounces which brought it up to nearly the top of the "full" segment on dipstick.....
I do not see any leaks and they said they had checked everything and found no leaks......
I will admit I had not checked this fluid level when I bought the coach and up until the incidences 2 weeks ago, I had no reason to question it.....
In any case.... I now know the reservoir is full, see no signs of any leakage on any of the jacks, the valves or lines. Time will tell - don't have any trips scheduled at this point other than to local Ford dealer for oil / filter / lube on Engine - and Oil / filter on generator.....  ( I get these done on the V10 for $29.99 - not complaining about that.)
Expecting this thread is likely over....Everyone's insight, experience, suggestions were interesting.

For what it is worth, I have the Kwikee Jacks and when on our first trip with the new to us coach we had a couple of issues with the
Jack system. We got to a site that required us to raise the coach higher then normal due to unlevelness of the site and the jacks
would not fully extend. After extending and retacting a few times I could hear that the hydraulic pump was sucking air mixed with the fluid.
Also the jacks were not fully retracting. I checked the fluid level and it was down so I bought some fluid, filled it -- no problem since
that occurence 3 years ago. The only other issue I had was with the control panel on the door. The panel stopped working when I
shut the door one time so I took the panel out, disconnected the power, reconnected it -- worked and no problem with the panel since.
I have restricted my use of the driver's side door since that happened however.
I really like the Kwikee steps and hopefully your issue will have been solved by adding fluid.

Thanks for the input..
Agree... they really do work neat... only issue was the warnings comming on...
And I do have to make sure when I use them that coach is nearly level because they will easily lift wheels off ground to do so..... try not to do that with some extra plank sections along for under the wheels in case....
So far it's been fine again but only used once since then and short 20-40 mi trips...
Fortunately, the control panel on mine is on front dash panel left and lower area under steering wheel below light switches ....
Optimistic ..
Hope yous continues to behave also...
