I have a Stanley Deluxe 810 model (1/3 HP). When I pressed the close button the door closes and then trys to reopen. When I disconnect the arm (that goes to the door), the door unit goes all the way to the closed position and bounces back, Therefore I have to hit the button to turn it off when the door is in the closed position or it automatically trys to re-open it again. Does this has something to do with the augmentation/diminuation control??
