Review on 🔩 LiftMaster Screw Drive Coupler 25C20 - Chamberlain Craftsman Garage Door Opener by Jeremy Floyd

Replaced it on my Liftmaster Professional and it helped! WARNING: If you opened your garage door after the original clutch broke, your open and close limits will be out of sync with the opener's memory. You can't just plug this in, relock the car door and press the button - you could damage the opener or your door. Release the cart until you see it move normally from the door to the opener. Unfortunately, there's no way to reset the restrictions, so leave them alone until you need to adjust them later. When installing a new clutch, you must turn the screwdriver BY HAND (using the clutch) to return the carriage to where it was when it broke - usually near the opener or door. It took me a good 10 minutes to turn around (switch hands!) to get mine back from the door to the opener. There he was when he broke. Once you get used to moving around the track with each push of a button, you can put it all back together and fine-tune the boundaries.
