One or more of these reasons is likely responsible for your garage door closing partially but not all the way.
Something blocking the door.
There is one on each side of the door.
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.
But the springs that are part of your overall garage door system balance the door in two ways.

Your garage door has set limit switches that instruct the motor when to stop running both when it is opening and when it is closing.
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.
If your garage door is not balanced right it won t go up or down all the way.
Most garage doors from the past 15 20 years have a photo eye which detects if a person or object is blocking the door from lowering all the way.
