Hi Everything home repair! We believe that with the right instructions, the right part, and some effort, problems like this can be diagnosed and don't require someone replacing the entire opener.
Thanks for the video, I had the same problem. I first replaced the easy stuff: Carrier and coupler (pronounced cup-ler, not coop-ler as some videos purport). They were not the solution. I suspect the ‘keeper’ wore out and either was ground up or popped out as I assembled this some 15 years ago. Had I missed that step it surely would have failed years sooner. Your video showed bending back (straightening) the ‘ears’ of the shafts to allow the installation of the collar. I would have been reluctant to do that! Thanks for making a point of showing that. With a vicegrip tool I did the same, but with trepidation; Several times on both shafts, till it became straighter. I also used a file to clean up the burrs and damage such that the collar would slide on. I set up some pulleys in the garage (working alone) so that I could disconnect the opener at both ends and lower down for the disassembly of the extrusions and worm gears. My repair area was at a juncture such that I had to remove the furthest extrusions and gears to repair and install the new collar and of course the keeper. It’s much quieter now and has been working for weeks…. It’s folks like you that take the time to pass on hard earned wisdom to make life easier for the rest of “us”. Thank again. “Felix”
Hi Alan: we no longer do service. We sold that part of the business a few years ago to a former employee. His company is Matt's Garage Doors, and they may be able to help you. Blessings!
