Check the balance of your door. Lift the garage door about half-way open as shown. Release the door. If properly balanced, the door should remain in place, supported entirely by its springs.

Most likely - the door is out of balance - meaning it will drop or close once you let go... That means -- springs are a problem and will need adjustment or replacement.
