Yesterday, I was cleaning out the front compartment and actually got inside the compartment. While there I noticed that the large wires to the relay adjacent to the motor, were loose, especially the center feed wire. I tightened the fasteners and, thinking I had fixed my slide problem, went inside to try to retract the door slide. No go. But I heard the motor run continuously while I held the switch down, so I'm pretty sure the circuit breakers aren't tripping. I then lubed the rack and pinions and guide tubes and while under there, I noticed that the vertical height adjuster bolts were not touching the brackets and also noticed that there was a corroded area above the bracket which appeared to indicate that the adjustment had moved from its original painted location. So I adjusted each bracket up about 1/8". I then tried to retract the slide and it came in but very hurky-jerky. So I went back out and adjusted one bracket back towards its original position. When I tried the slide again, it was a hit and miss operation and seemed most successful when I first attempted to extend and then retract.
So I know how to make the vertical adjustment to the slide but I don't know what defines a need for this adjustment, and which way I need to adjust to get the desired result because I'm not even sure of the desired result.
This slide is the typical rack and pinion and rail system, and does drop into place when fully extended. There is a ramp the full length of the slide and I thought about lubing that as well but I was afraid that would get lube all over the carpet as the slide came in.
