Seals sticking? Something under or between the slide and the floor or wall? Not level and getting in a slight bind? Gears need lubricant? Could be slack in the gear linkage causing it to turn slightly before it catches to move out. Could be multiple things. Get someone to activate the switch while you look closely at where it is sticking to determine what's causing it. If it's the seals, then a light application of baby powder might help. Start simple and work your way to complicated. Always the best practice.
