Quick Take
If your door refuses to close at the same time every day, low sunlight is probably blinding a safety sensor. Wipe the lenses, check the alignment, and shade the sunny sensor with your hand to test it. If that fixes it, a small sun shield fixes it for good.
The Door That Refuses at 7 AM
You press the button. The door starts down, stops, reverses, and the opener light blinks at you. You try again and get the same result. Most people assume the opener is dying. In Las Vegas, the more common culprit sits six inches off the floor.
The safety sensors work by beaming an invisible light across the door opening. If anything breaks the beam, the door refuses to close. Direct low sunlight can flood a sensor so completely that it acts blocked. East facing garages get it in the morning. West facing garages get it in the evening. Then the sun climbs and the door magically works again.
The Five Minute Checklist
First, look at both sensor lights. Steady lights usually mean all is well. A blinking or dark light means blocked, bumped, or blinded. Second, wipe both lenses. Vegas dust films them enough to weaken the beam.
Third, check alignment. Brooms and bikes knock sensors out of line all the time, and the two eyes must face each other squarely. Fourth, look for the sun. If the problem keeps a schedule, glare is your suspect. Shade the sunny sensor with your hand and try the door. Fifth, check the small wires for damage.
Fixes That Last
For confirmed sun glare, the fixes are simple. Small sun shields that shade the sensor. Swapping which side each sensor sits on. Or a slight change in position. All quick, and all permanent.
What you should never do is bypass the sensors. They are the thing standing between a closing door and a kid, a pet, or a bumper. Sensor repair is fast and cheap. If the checklist does not solve it, that is what we are for.
