If your garage door falls too fast when you decide to close it then the problem may be one of these.
Garage door falls down.
If the garage door suddenly comes crashing down and will not go back up this is usually the result of a snapped cable.
Let s take a deeper look into each cause.
The garage door can fall too quickly as a result of springs that have become too loose.
It can also be due to to cables that are broken.
Probably due for a spring failure.
The cables experience wear and tear after years of helping to control the movement of the door and the tension of the springs.
When your garage door falls too quickly it is a symptom that something is loose of broken.
Set a safety ladder under the garage door opener.
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.
If it falls to the floor you may have a broken balance spring on the door frame.
Locate the limit switch adjustment either on the back of the opener or behind the light bulb s lens cover.
Another cause of this problem is poorly installed springs and cables or a damaged garage door track.
If the door is balances then i agree with don in that the drive gears in the motor head may be worn out from a heavy door.
Snapped cables should be professionally replaced before you try to use the door again.
Collision also covers the upset of your vehicle.
If you remove the cover you will see a lot of white plastic pieces inside the cover which will indicate you will need to install a gear kit.
I d think it is also possible the cable had an issue when it wound up in the spool and slipped as it reached the top.
Also it could be due to springs and cables that have been poorly installed or a damaged garage door track.
Typically this happens because of springs that have become too loose or cables that are broken.
