Garage Door Opener Problem

I have a 1/2 HP Craftsman GDO. I just replaced the worm gear and now the door goes up and hits the frame of the opener and stops. It makes a humming sound and locks in place.

Any ideas on what adjustments need to be made. Also, is there a way to restore the factory settings on the opener?

Thanks in advance for the help.
