My garage door opens about six inches and stops i press the button twice so it will stop going down and then is goes up another 6 inches or so.

Garage door only goes down a few inches.

Try to operate the garage door manually this helps you determine if the problem is related to the door or the motor. This is almost always the result of a dirty or obstructed safety feature. Clicking the remote at that point just closes it. The garage door can be operated manually by disconnecting the garage door opener from the door using the red pull cord.

Continue to turn the down. It goes partway down reverses direction and goes back up again. Try to lower the door. For most doors a complete rotation of the screw allows the door to advance 2 inches.

If the door is working properly it should be easy to lift by hand. My garage door will open only a few inches and then stops.
