Big slide making a bad noise

[bobfears]

My 2012 Primetime Tracer 2800RLD slide is having a problem. It has the Accuslide brand slide mechanism. Extending the slide is no problem, but when you attempt to retract the slide it is reluctant to move. It stays put for about 15 to 30 seconds and then it starts to move. After going about half way in makes a grinding noise and comes to halt. To get it going again you have pull from the inside while someone pushes the retract switch. It then starts to move and the grinding noise stops and it closes. Also you have to be plugged to shore power for the slide to work. The battery indicator light inside the coach says the battery is fully charged when this happens. Any help you give me would be appreciated. The Accuslide mechanism uses a series of 4 cables to pull the slide in and out.

I'd try hand cranking full open to full closed once so you can see exactly where and how much it's binding. Look for any signs of water intrusion that may be making the wood frame swell (one possibility for the binding). If no signs of water leak and you can feel it bind in a particular place it may be easier to find the reason when taking the motor out of play.
Good luck / Skip
