Two Small Units Near the Floor Decide Whether the Door Closes

The two small units mounted low beside the door project a beam across the opening. A break in that beam stops the opener from closing, or sends the door back up on the way down.

Most faults come from a dirty lens, a bracket that has been knocked or a damaged wire. We clean, re-aim and test, replace the part if needed, and note how the sensors were set so future checks start from a known position.

Sensor Trouble to Watch For

  • A blinking light on the opener

    A light that flashes when you press the wall button usually reports a sensor problem, often a broken beam or a loose connection.

  • Door closes, then reverses

    If the door touches the floor and rises, or stops partway down, the beam is probably being interrupted or a lens is dirty.

  • Indicator lights out of step

    Each sensor has a small light. When one is dark or blinking while the other holds steady, the pair is not communicating.

How Sensors Are Put Right

  1. 1

    Clean and inspect

    Each lens gets a wipe, each bracket a test for movement, and the wire is traced along its length for cuts or staples that pinch it.

  2. 2

    Re-aim or replace

    Sensors are aimed at each other until both lights hold steady. A unit that stays erratic is replaced as a matching pair.

  3. 3

    Test the reversing

    The door is closed against an obstruction to confirm it reverses, and the beam is interrupted with an object to confirm the sensors respond.

Questions Owners Ask

Why does sunlight upset my sensors?
Direct sun on a receiver lens can wash out the beam and make the door misbehave at certain hours. Shading the lens or adjusting its angle often helps. If it keeps happening, a sensor swap is the next step.
Can I bypass the sensors to close the door?
Do not disable them. They are one of the main ways the opener stops for a person, pet or object. Holding the wall button closes the door on many models, but that is a short-term workaround, not a fix.
How often should sensors be checked?
A wipe and a glance at the indicator lights every few months is enough for most homes. A yearly visit adds a test of the reverse function and an inspection of the brackets and wiring.
