2009 DS 4086 Passenger Slide

[Bahcml]

Just got it out of storage, everything fine EXCEPT passenger front slide will not extend. Locks disengage and then the sound of silence. Nothing. We know nothing about what the problem might be. Any info/suggestion much appreciated.
Please note, I erroneously entered 2019 (I wish) is a 2009.

If your slide out controllers are the same, easiest to swap controllers to test. If it works after the swap then it is the controller.

Controllers are in the bay on the passenger side. I agree to swap them. You might also have a small dial in the lower corner of the controller. Mark where it is and you can turn that up and see if it gets the room moving.

So, after a sleepless night, and a night of the coach being plugged into 50 amp the darn thing extended and retracted (3X) just like it should.
Conclusion: low batteries.
Time will tell if this is the correct conclusion.
Thanks to all for the suggestions, will print them out for use if further problems develop.
