[quote GGD]Could possibly be the wiring between the sensors and the motor unit. ...
Another way of saying this is that the logic board is going bad, and if so, there likely isn't a "PRAM" or "CUDA" reset that'll be permanent. Logic boards can be replaced (I think they call them "receiver" or "main" boards in garage opener parlance) but might not be worth the expense. You don't need to hire someone to replace it.
I agree that the symptoms you describe sound like only a bad sensor, but I see some parallels to a situation that happened to mine that you should be aware of.
I have an opener that began to exhibit not responding to the remote but would always work at the wall. There's a reset/programming switch on mine I was instructed to press. Voila, everything worked again.
I was warned however that the problem was likely caused by a storm or brownout, and that the symptom, or others would soon ensue. Now the door won't close with the remote, and the only way to close it at the wall is to hold the button down until the door stops --- there are no obstructions anywhere, and the door is well balanced, and yet it'll act as if there's an obstruction and reverse itself unless the button is held down the whole time.
It's 'lil computer brain is toast, in my case, just not to the point where it's completely failed to run the motor.
