Genie Pro 88 Won't Close



Question:
I have a old Genie Pro 88 garage door opener. The door opens fine but when I try to close it is moves a few inches and then auto reverses. I tried adjusting the auto sesitivity screw at the back of the opener but that didn't help. WHat should I be aiming fro when I turn this acrew? Should I turn it until the door reaches a certain position? What is that position? Or is there something else I need to adjust.

Answer:
First disconnect the door from the opener by pulling the emergency rope, then move the door manually through its entire range. It should be balanced well enough that you can move it all the way up and down with only a few fingers. If it doesn't move easily, it needs to be rebalanced. If your door is balanced, it's unusual. Most doors are _way_ off. They start off balanced, but nobody has the door guy come out every year for a tune-up. The opener works harder and harder as time goes on, until the load is just too big to handle. That's when your problem appears. You can find web sites that will walk you through the tuning process. Most of it is pretty straightforward, like getting the tracks straight and oiling the rollers, but the springs can be a bear. They can take off your head if they let go at just the right time. I've had them make holes in walls--nasty ones. (I don't mess with springs any more.) As for oiling, get a spray can of lubricant that's designed for garage doors. You put it only on the rollers and other moving parts, not the track.
