I had the same problem with my garage door opener. Tried shading the sensor but it still didn't work reliably. Finally replaced both the sensor and transmitter and it has been good ever since. My theory is that the lens got dirty or scratched over the years and was picking up stray light from odd angles.

+1, I had this issue as well and went through a bunch of futile efforts to block the sun and the angle and wish I had replaced the transmitter a lot sooner instead of trying to move trash cans because that worked 50% of the time. I think this is the kit I bought: https://www.chamberlain.com/safety-sensor-kit/p/041A5034
