I'm having an issue with a Sears garage door opener. It's probably 8 years old, and has always worked fine. Here lately, when the button is pressed, it only goes up a few inches. Press the button again, it goes down, press it again, it may go up all the way, or you may repeat this drill 2 or 3 more times. It's chain driven. I adjusted the "raise" pressure screw on the back a while back, and it seemed to fix the problem. I now have it set as high as it will go. Is it just worn out? It doesn't bother me much, but my wife parks HER car in the attached garage, etc, etc, etc.
