Fast easy step by step process on how to properly program your garage door travel system.
If the door is working properly it should be easy to lift by hand.
Here s a rundown of some of the possible reasons this can be happening.
If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch.
Garage door only travels a little way and then reverses does your garage door only travel a little way 6 inches or so and then reverse.
Your travel down setting needs to be adjusted.
When the garage door opens about halfway or 5 feet from the ground and stops the up limit switch needs to be adjusted.
It goes partway down reverses direction and goes back up again.
In order to fix this you ll want to make small changes to the close limit setting until the door opener knows to stop once the door has reached the floor.
A broken torsion spring will also cause the door to slam closed instead of closing gently.
This is almost always the result of a dirty or obstructed safety feature.
If broken or out of adjustment the door will be exceptionally heavy thus putting excess strain on your garage door opener.
Possible reasons why your garage door hits the floor then goes back up.

Open the garage door and watch it closely as it opens.
You push the button to close the garage door.
As is the case with so many issues at the home there s no one reason why your garage door closes then opens.
