Sounds and symptoms worth a phone call
A loud bang from the garage is often a torsion spring letting go. Other signs are just as clear: the door rises a foot and stops, a cable hangs loose off its drum, the door sits crooked in the opening, or a roller keeps popping out of the track. Any of these is a reason to call, whatever the age or condition of the door.
If you suspect a broken spring, stop pressing the opener. The motor will strain against a door it cannot lift, and the stored force in the spring and cables is not something to test with a wrench from the driveway. Leave the door where it is and call (309) 357-3907 during business hours.
