Slipping down a few inches after opening posted.
My garage door slides down after opening.
No pieces of plastic to show wear and tear.
There are two different types of spring systems for garage doors.
Probably due for a spring failure.

Second because of the weak springs the clutch brake in the opener may be.
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.
Garage door opener problem.
They need to be set to open the door fully without the opener.
If your garage door slips down below the header after you have opened it you garage door springs need to be adjusted.
This model looks like it is new and i would first check the balance of the door by closing the door and releasing it from the opener and lifting the door by hand to waist lever and releasing it to see if it stays in that position or if it slams to the floor.
Sometimes the door will open all the way up after it slides back and the light will turn off.
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.
Took cover off and gears appear to be fine.
Garage door opens all the way up and then slides back about 4 6 inches.
If it falls to the floor you may have a broken balance spring on the door frame.
