craftsman garage door opener close and open again

We have a craftsman garage door opener (part number: 41A4315-7D, dated as 12/02). It closes and then opens again when the door touches the ground. Does anyone have any idea what the problem could be and how to fix it? Thanks,

First make sure there is nothing between the bottom of the door and the floor. If not, your door is evidently expecting to travel downward further to fully close.
There is a 'down limit' adjustment screw on the side of the drive unit. Turn in in the direction indicated to decrease the travel in about 1/2" increments until it no longer reverses.
This is also a good time to check the chain tension and security and proper operation of all associated hardware, including the neutral balance of the door when operated manually.

If the door reverses after it hits the floor then it is traveling to far. Adjust the down limit located on the side of the motor unit. You will need a small screwdriver and you will need to turn the control in the opposite direction of the arrow printed on the cover. If the main light on the opener is flashing 10 times as the door reverses you have a sensor problem and will most likely need to adjust them so they are pointed at one another.

When we wanted to install an opener in our old place, everyone swore about the craftman openers so we had one installed around 2002 and from the git go it had that problem ALL THE TIME, drove us nuts. It was the worst opener ever and we then understood why many refer to the craftsman products as "crapsmen". After moving into our home 2.5 yrs ago, we had the same problem with the craftsmen that came with the house. We replaced it with a Champion, have not had a problem ever since.
