QUICK ANSWER
Safety sensors are the small eyes near the floor that tell the opener a person or a car is in the way. Sun, a bumped bracket, or a spider web can make a good door reverse. Atlas realigns or replaces them and confirms the auto-reverse still works.
A homepage review describes a door that would not open until a misaligned sensor was corrected. That is this job.
Why sensors act up in Anaheim
Low afternoon sun
West-facing openings get glare straight into the receiving eye. The door then refuses to close until evening.
A bracket that got kicked
Trash cans and bike tires tap the sensor. A few degrees of tilt is enough to break the beam.
A wire pulled loose
Staples and door hardware can nick the sensor wire. We trace it before replacing the eyes.

HOW ATLAS FIXES IT
We clean and aim the eyes, check the wiring, and only then replace a dead sensor. After that we test the opener close-force so a real obstacle still reverses the door.

Bypassing the eyes so the door will shut removes the safety the opener is built around. If you need the door closed tonight and the sensors will not cooperate, call the 24/7 line instead of defeating the beam.

Questions about safety sensors
Why does the door reverse before it shuts?
The safety sensors are the first place we look, especially on west-facing doors in low sun. We aim them and test the reverse.
Can I tape over the sensors?
No. That removes the safety that stops the door for a person or a pet. Call instead.
