Slide-out issue: motor running, slide not moving

It's a 2016 178 with lippert slide-out system. 

Tried search but couldn't find any info. esp. on DIY. 

The motor runs but slide-out won't move, though I could manually move the slide-out in and out uisng a wrench without much issue. 

It might be the gear in the actuator from what I read. 

Have anyone tried to remove the motor/actuator assembly and replaced gear? 

Thanks a lot. 

On mine there is a computer controller that operates the slide out.  It has a blink code when there is a failure as well as a manual bypass. On mine there was a piece of panel that was obstructing the slide out.  It doesn't take very much resistance to shut down the motors.  With mine I could shove on it while it was going out and it would eventually get out.  At any rate the link above is to some of the manuals I found.  Also the RV dealer that was close to me sent me a Schwintek troubleshooting guide.  Hope this helps
