Jayco slide out re syncing

Jayco slide out

Our Jayco caravan comes with a bedroom slide out. This increases our internal space a lot by being able to extend the side of the caravan when parked up. But what happens when it doesn't want to play nicely and gets out of sync ?. Well luckily or unluckily depending how you look at it we have experienced this issue.
 
While miles away from a Jayco dealer we ended up having to deal with it ourselves. The upside with having to deal with random issues is you gain more knowledge about the everyday things. This also leads to being less nervous about operating something gently because it might pack up and you don't understand it. So below is an outline of what i came across in today's issue.

The Jayco slide out:

Schwintek in wall slide out

To save you a fair bit of googling. The mechanism used by Jayco and a lot of other RV dealers to run the slide out is a system called the Schwintek in wall slide out. Created by Lippert components in the USA. It comprises of surprisingly very little considering the work it does. Two small motors, 2 x aluminium rails a couple of gearboxes and a synchronizing electronic controller.

Important operational note:

It's recommended from the manufacturer
  • To continue to push the in or out button for 3 to 5 seconds after the motors have stopped making noise.
You can't cause the slide out to end up on the ground if you hold your finger on the button for too long. The electronics will take care of shutting the system down once the slide out is in place.  The trick is, once you've started to operate the slide out DO NOT take you finger off the button unless the slide out is either fully extended and the motors have stopped by themselves or completely retracted.
 
If you happen to start moving the slide out then stop operating it mid operation this is how you will cause the motors to get "out of sync".
 
If this happens you will find the slideout doesn't close up or extend evenly. Such as the case we ended up with this morning. Although in our case it wasn't due to stopping in mid operation, it just happened.

To re sync 

There is no adjustment of a cable to play with. You don't have to remove the gears and put them a couple of further notches down the track. If you're striking the same issue with syncing the motors here's how to fix it.
 
  1. Fully extend the slide-out. ( Once the slide out stops moving continue to hold your finger on the button for up to 5 seconds
 
  1. Retract slide-out roughly 1 inch. Take your finger off the button  despite previously being told never to do that 🙂
 
  1. Repeat steps 1 and step 2 at least 3 times  
 
By completing these above three steps your slide out should re sync itself. So now fully retract the slide out to test the operation and see if it's come right. ( Remember to hold finger on the button until after the motors have stopped)
 
Are you stuck in the outback and it just won't do anything ?

Don't panic, there's a couple of things you can do to bring your slide out back in if it's not budging at all.

  1. Enable the manual over ride on the control unit. ( ours is under the bed) see this link on how to do it 
  2. Disconnect the motors which is easily done. See this video here 
  3. Trouble shooting guide LCI video
  4. Download the slideout manual

If all's good , time to pour a drink and relax. If not you're going to have to get in touch with a dealer and have them look into it.

 

Happy travels

    Very helpful. We’ve experienced a bit of trouble with ours. The worst was in Mildura when the electronics on one side died and yet the slideout was able to retract even though it was a bit wobbly. Had to get a new controller $400+… ouch. Had it inspected on return home and have since had extra rollers fitted under the slide to support the section. I was given similar instruction re either all in or all out.

    great info we have had these problems and fixed as instructions yes 5 secs is important to make sure they run parallel..but jayco never tell you any of this ?????

    Opps sorry about the slow reply, just found your comments sitting in the “waiting to be approved” folder.

    Glad you got your issue sorted as well, can be frustrating at first until you realise how simple it potentially is 🙂

      Larry,
      just reading your post and wondering if you tried to remove the motor completely from its housing, I have a dead motor and none of the information on the internet show which side to get the motor out for Australian motorhomes. Can it be removed from the outside or once you remove the crew which is located on the outside at the top do you need to go into the motorhome to remove the motor.

      Cheers

      Ian

        Hi Ian, i haven’t had the pleasure of replacing a motor. But as per the video listed at the end of the post ( #2) it looks as though it can all be done from outside of the motorhome… check out the video here https://www.youtube.com/watch?v=DviEbWT3lUo

        Hope that helps and good luck

    Thanks mate ours seemed to be twisted as I had a tissue box caught as I was closing one day. After doing this it doesnt twist any more. Good job :):)

      That’s so great to hear Charmaine!
      I’m glad it could be sorted out with the information Larry gave. It sure saves money and stress when your in a pickle.
      Thanks so much for letting us know that our info was helpful 😀
      Happy travels

    There is a bit more to slide out problems in the Schwintek slide out than the above article mentions, the most common problem occurs when the controller settings are lost. This causes the slide out to slide out or retract unevenly and can cause major mechanical problems. This condition is often caused by low battery voltage. The fix is quite simple but the first time that you do it it makes you nervous as you are operating the motors on maximum power which can overdrive the mechanism if you hold the button too long after the slide out reaches one of the extremities. What has happened? The controller is programmed to provide just enough current to move the slide out to keep both motors moving at the same rate. When it reached the extremity of travel the motors can’t continue to spin and as a result they try to spin by drawing more current. The controller senses the extra current demand and this signals that the slide out is either fully out or fully in. The controller then shuts off the current to the motors and engages the locking mechanism. The reprogramming sequence provides maximum voltage to the motors so it can sense how much current is needed to move the slide out evenly on each side. If you continue to hold the in/out button after the slide out reaches an extremity it may be possible to strip a gear so it is essential that you either release the button a little short of the extremity or as soon as it reaches an extremity.
    This reprogramming sequence is in the manual that is online and it goes as follows.
    Electronic Manual Override (Controllers C-1 and C-2 Only)
    NOTE: See (Fig. 5) for locations of the mode button and LEDs.
    1. Press the mode button on the controller six times and hold on the seventh for five seconds to enter electronic manual override mode.
    2. Use the extend/retract switch to move both motors in or out.
    NOTE: Over-current and short circuit detection are disabled. Electronic manual override provides 12V directly to both motors.
    3. To exit the mode, push and hold the mode button until the LEDs begin to blink simultaneously. Exiting the override mode resets the motor positions.
    The manual can be found at: https://liferebooted.net/2018-phaeton-40ih/Schwintek-Slide-Owners-Manual.pdf
    Or many other web addresses.
