Because it hums when you try to open it the battery is working properly. When you have made your adjustment test the door by lowering and raising it. What you ll need when you find that your garage door motor is making a humming noise but not opening and closing it typically means that it has gone off track or needs some sort of small adjustment. With a screwdriver adjust these screws.

There are force adjustment screws on the back of the garage door opener unit. Locate the force adjustment screw. To change the down force and the up force of your opener find the force adjustment knob and turn it to adjust the up force or down force. Turn the screw a quarter turn at a time and retest after each adjustment until the door opens completely.

You can increase the up force by turning the adjustment screw clockwise. Alternatively turn the screw. Test by opening and closing the door. Test and adjust the door opener s reverse feature.
