There are two different types of spring systems for garage doors.
Once it slides down does it go back up and stop in the correct place if it doesn t maybe the gear or gear shaft on the motor is stripped.
Torsion springs are mounted directly above the door and need to be wound with special tools.
It depends on the particular door but if you have a two car garage with on wide door getting 7 years out of a set of springs is pretty good.
Probably due for a spring failure.
No pieces of plastic to show wear and tear.
If your garage door slips down below the header after you have opened it you garage door springs need to be adjusted.

Second because of the weak springs the clutch brake in the opener may be.
If it falls to the floor you may have a broken balance spring on the door frame.
Once the door is up all the way it s resting on the horizontal parts of the track and the resistance of the motor to turning because it is low geared should prevent it coming back down.
First is your door springs are in need of adjustment.
