Active Door recommends checking the balance of your door once a year. To do this, close the door and then pull the red disconnect rope on your garage door opener. After pulling the disconnect rope the door should stay on the floor. Next, raise the door about half way open, the door should stay at that position. And finally, raise the door all the way to the open position, where the door should remain open. If your door fails any of these tests, we recommend service by a trained technician.
