how do I reprogram my garage door opener? Craftsman K 727 model # 139.5377B garage door HBW1D3469
For the craftsman opener you can go to managemyhome.com and on the left hand side of the page enter 139.5377 and you can download a file for it. As far as the door is concerned you need to find the manufacturer and go to their web site.
This would be a good time to replace the batteries. Find the colored learn button on the motor head. It will be on the back or side of it. It will be the only button you can actually push. Push and hold this button until the led light by it goes out. << Press the same button and then press the button on the remote you want to operate the door. The light bulb should flash once to tell you it is programmed>> Follow these << >> directions for each remote. If you have a outside keypad press the button and then enter the 4 digit code followed by pressing the up/down button. Again the light should flash. Thanks BBMember
