The red light in the door sensor is blinking.

I found a manual and found out that the red LED blinks when the
sensors are not aligned.
The LED is supposed to be on all the time.

Should be a simple repair.

Damn funny what an instruction manual can tell you. *On mine,
there are certain times of the day when sunlight shines on it
that it will not close but do the up and down thing until you
stand in front of the sun and shade it.

BTDT. From the door rail to the inside wall corners is about 18-20
inches on both of my garage doors. The single door facing west gets
serious sun at triple digits much of the summer.

An installer, suggested placing a wooden block on the wall, same
height, but closer to the corner wall. This would allow the sensor
to be in a shaded location and not have it bothered by the sun.

In my case I had new sensors put in. So far no problem with sun or
heat. We placed them at the original location, but they are better
sensors.

I saw in the manual about the effect of sun on the sensers.

Putting a "hood" around the senser might work too.

Consider swapping the sender and receiver, so the receiver is in the
shade. If your opener is picky about which one is on which wire, swap
the wires at the screw-downs on the opener.
