Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
The garage door only opens partially and then stops about a fifth of the way up. I have detatched the emergency rope from the bracket on the belt and manually opened and closed the door.
I re-attached the door to the drive belt again from the fully opened position and it closes perfectly but again only opened partially.
Any suggestions would be awesome. Thanks
IF THE DOOR WORKS WELL MANUALLY.
ADJUST THE UP SENSITIVITY ABOUT 1/8 TURN AND TRY AGAIN.
HOPE THIS HELPS
