I'm having difficulty finding my problem in the previous posts because they discuss so many different types of problems. Here's mine.

I have a Craftsman garage door opener 3/4 hp.

All remotes stopped working at the same time, but the wired manual wall switch works fine. The safety sensors show a green light and an orange light. If I obstruct the sensors, the green light goes out and the door will not close with the wall switch.

The proper lights go on an off in sequence when programing the either remote. When I press the remote, the programing light (on the card) blinks weakly for as long as I hold down the button.

I replaced the controller card, but have the same symptoms.

I'm clueless.

Any ideas.
