Garage will not close

jbhollowellSeptember 26, 2011

I have a 1/2 hp Craftsman. When I push the remote it will try to close but at various stages 1/4, 1/2 and 3/4 way down it opens and then the light flashes 5 times. I have checked the laser sensors and they seemed to be aligned. One is a steady green and the other is a steady amber. I can close the door by holding the wall button until it is all of the way shut. Please help...I would rather not pay the astronomical fee of getting someone to look at it.

Thank you for reporting this comment. Undo

If when the door reverses to the open position the main light flashes 10 times it is a door sensor problem. Make sure the small light on each sensor are on and not flickering ever so slightly. (check closely) Tweak them a little even though they may seem to be okay. Check for 5vdc between terminals 2 and 3 on the rear of the motor unit. If there is no voltage or if it is greater than 6vdc the logic board is bad.
