I have a Powerlift Garage Door Opener model WR77, serial number 011284. One of the springs broke, I repaired it, but now the door goes up about a foot and then goes back down. It cycles doing that until I hit the button again to stop it. What do I need to do to make it open all the way like it should? Help!!!
