Well, it looks like my garage door opener won't close anymore this last time it got real cold. It thinks that there's an optical obstruction. The two parts of the optical sensor have an LED on them - one is always on. The other one is on... but... here's the kicker...
It flickers! It's mostly on but there's some rapid, barely noticeable 'off' times. It's so subtle that I'm not sure if people can easily notice it flickers off.
I can put my hand between the sender and receiver, and the LED will completely shut off.
I tried jiggling the receiver a bit but could not get the LED to stop flickering. I didn't try jiggling the sender because I can't see the receiver while jiggling. I also tried cleaning the optics end with a damp paper towel.
Anyone seen this before?
