If you find that your garage door is reversing before even hitting the floor then it could be possible that there is a problem with the close force setting.
This setting basically controls how much force is allowed when closing the garage door.
Continue to turn the down.
Replace them if they re broken.
Your limit switch needs to be adjusted.
If the garage door only travels down an inch or so before reversing something is probably blocking the beam between the two safety sensors at the bottom of the rails or the sensors aren t aligned.
Photo eyes or safety sensors are mounted to the track on either side of the garage door about 6 inches up from the ground.
Turn the down adjustment one full turn counterclockwise.
This is almost always the result of a dirty or obstructed safety feature.
But changes in weather conditions can causes your garage door components to shift or contract.
If the door closes and reverses it is traveling too far and you should decrease the travel.
If the door reverses part way down and you are sure there is no obstruction or binding increase the closing force a small amount and try it again.
You push the button to close the garage door.
When that happens the distance your garage door needs to travel may change.
