| I have a Craftsman 1/2 hp Garage Door Opener (41a5021) When I hit the button to close (wired or wireless) it does so, but when it hits the bottom, it immediately begins to open.
Any Ideas? Thanks |

| If you have the manual, It should explain how to adjust the up and down force adjustments on the opener. I believe the down force adjustment needs tweaked. |

| If the door hits the floor and then reverses it is closing a little too far. On the side of the motor unit you will find the 'down limit' control. Turn this a couple turns in the direction opposite the arrow printed on the cover. You may have to tweak this control a bit to get it just right. |
