Craftsman 1/2 HP Garage Door Opener
I'm having trouble with my garage door opener (Craftsman 1/2 HP 41A4315-7C). It only opens half way and then stops. When I push the button again (either the wall panel or remote) it will close. Sometimes it will open all the way. There are no obstructions since the door opens fine on it's own(not connected). Also without the door attached to the drive it will still open halfway sometimes and all the way other times. Any idesas? It's 11 years old and was in the house when I moved in. Could it be wearing out and in need of replacement? Thanks.
