1st off understand the mechanics of the slide room.
Its a box with one side missing. 2 motors one on each shaft rotate a top and a bottom gear against the tracks attached to each side of the box. that moves the box in or out.
The top and bottom should stay in sync because they are both fixed to the shaft so that the top or bottom doesn't get ahead or behind the other. The sides extending and retracting in sync rely on the motors knowing when they have reached their retracted or extended position. this is determined by the controller "measuring" the "resistance" to turning the shaft. these can get out of sync from a variety of causes.
Proper operation of the slide room is key to allowing the controller to keep the slide motors in sync.
The room is stable when fully extended or fully retracted because it seats against the inside or outside of trailer wall. In between its a teeter totter. But, when fully retracted, the inside edge is not resting on anything so care in the retracted position is very much needed.
so a couple of "rules" I've learned on this board and a variety of YouTubes,...
1. Treat the fully retracted slide carefully, avoid using it (sitting in it) when retracted, don't over load those large storage areas under the seats. Couple hundred pounds max (Hat tip to Marine359)
2. Operating the slide should be one fluid movement from fully retracted to fully extended and vice versa. That means press the button (Extend or Retract) and HOLD IT UNTIL THE MOTORS STOP *and continue to hold for 3 seconds*
This allows the controller to learn the resistance of the motors in normal operations.
3. Check the floor and the roof for objects that could impede movement before retracting the slide room. Especially that narrow space between the room and the Medius center.
4. Lube the mechanism periodically and properly.

All well and good but there is also assembly and, fit and finish, issues. It's the nature of the industry. Don't get me started.
Lippert identified an unelaborated issue with the manufacture of slides mechanisms that were subsequently installed in Micro Minnies. Been discussed previously

Another Tip I learned on this board and I'll pass along,...
when searching this board use the Google search box at the top of the page. It will very often get you back to a relevant post on this board more quickly and accurately than using the boards search functions (hat tip to creativepart)
These are, In my opinion, a very basic set of operation instructions that should be provided with any slide equipped RV. There are many YouTube videos that can provide more in-depth knowledge. (Caveat Emptor)
