Releasing the door from the operator

If your automatic garage door opener is stuck closed because of a power failure or due to a problem with the unit itself, you may still be able to open the door manually. Modern day operators allow you disengage the garage door’s automatic operation providing full access to your garage. As a means of caution, close the garage door so it is fully closed.  You will notice a dangling, red pull-cord three-quarters the length of the boom away from the garage opening. With the garage door now closed, simply pull the red release cord down toward the floor. This should disengage automatic operation and allow you to manually open/close the garage door using your own strength.
