My Garage Door Slides Down After Opening

There are two different types of spring systems for garage doors.

My garage door slides down after opening.

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. First is your door springs are in need of adjustment. They need to be set to open the door fully without the opener. On 5 10 16 at 1 33 pm to sicboy.

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. Probably due for a spring failure. 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. 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.

Torsion springs are mounted directly above the door and need to be wound with special tools. Took cover off and gears appear to be fine. Slipping down a few inches after opening posted. If it falls to the floor you may have a broken balance spring on the door frame.

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. Sometimes the door will open all the way up after it slides back and the light will turn off.
