I have a Craftsman Garage door opener. It is about 4 years old. for the past month or so, when opening the door it opens fine, but when closing it, half the time, you have to hit the remote 5 or 6 times before it will close. If I use the button by the house it works fine. At first I was thinking the sensors just weren't aligned right but they are fine and the lights stay lit and flash when something crosses in front of it.
Any idea what it could be? It is with all remotes including the key pad.
