The safety eyes and the fix

Garage door sensor repair starts with the two eyes at the floor

Garage door sensor repair deals with the pair of photo eyes fixed low on either side of the door, a few inches off the floor. One eye sends an invisible infrared beam across the opening, and the other receives it. If anything breaks the beam while the door is closing, the opener stops and reverses. That is the safety rule that protects a child, a pet or a bumper, and it is why a door with a fault in the eyes will refuse to close at all.

Most sensor trouble comes from a short list. A bracket gets knocked by a bin or a bike and the eyes drift out of line. Dust, spider webs or low sun on the lens confuse the receiver. A wire has been stapled too tight, chewed or pulled loose at a terminal. Or the sensor has simply aged and the electronics inside have failed. Each fault has a different fix, so we test the eyes with a meter and by eye before we replace anything.

It is tempting to tape the eyes together or hold the wall button down to get the door shut. That works once, but it removes the protection that makes the door safe, and it hides the real fault. Better to leave the door as it is and let us look.

Why call us

What we check before we replace a sensor

Alignment of the two eyes

The sender and receiver have to face each other squarely. A bracket bent by a few degrees can be enough to break the signal.

Lens and light

We clean the lenses and look at the way sunlight falls across the door opening. Strong low sun can blind the receiver for part of the day.

Wire runs and terminals

We follow the thin sensor wire from each eye to the opener, looking for pinches, cuts and corroded terminals, which are the faults a simple wipe will not cure.

Brand and compatibility

Genie, LiftMaster and other openers use their own sensor pairs. We match the replacement to your opener, so the new eyes talk to the logic board correctly.

The opener itself

If the eyes pass every test and the door still refuses, the fault may sit in the opener's board. We tell you so before you pay for sensors you did not need.

How it works

How a sensor repair goes

  1. 01

    Tell us what you see

    Say which lights are blinking, whether the door closes partway, and when the trouble began.

  2. 02

    We test the eyes in your garage

    A uniformed technician checks alignment, wiring and both sensors, then explains what is wrong before touching anything.

  3. 03

    You hear the price first

    If a cleaning and realignment fixes it, we say so. If the pair needs replacing, you get the quote before work begins.

  4. 04

    We fix it and prove it

    We realign or replace the sensors, then test the door by placing an object in the beam and checking that it reverses. The work is backed by a parts-and-labor warranty.

CALL NOW: (860) 532-6786

If the door closes then climbs back up, or the opener lights flash and nothing moves, the sensors are the first suspect.

Describe it and we will tell you what to expect.

FAQ

Sensor questions answered

Why does my garage door go down and then back up?
The opener thinks something is in the way. Usually the eyes are misaligned or dirty, but a travel limit set wrong can also do it. Wipe both lenses with a soft cloth and look for a bracket that has been bumped, and if the door still reverses, call us.
Can I fix a garage door sensor myself?
Cleaning the lenses and nudging a bracket back into line is fine for most people. Rewiring terminals or replacing a pair is easier to get wrong, and a sensor that is almost working can be worse than one that has failed outright. We handle those jobs.
How do I know whether I need a new sensor or just an adjustment?
If the indicator lights come on when the eyes face each other and go out when you block the beam, the sensors are probably fine. Dead lights, or lights that flicker when you wiggle the wire, point to a replacement. We test both ways before we quote.
Do you replace Genie garage door sensors?
Yes. We replace Genie sensors, along with those on LiftMaster and other brands, using a matched pair that suits your opener. The replacement has to fit the opener's board, so we check the model first.
What does a sensor replacement cost?
The price depends on the brand and model of opener, whether one eye or both need replacing, and how much of the wire run has to be redone. Most of the cost is the parts, and we give you the exact amount before we begin.
My opener's lights flash and the door will not close. Can I use the door in the meantime?
You can usually raise the door and use it open, but do not rely on a closing door until the eyes work. Park outside the path of the door and keep children away from it. If the opener itself turns out to be the problem, we repair those too, and on an old unit a new opener is sometimes the better answer.

Door will not close with the safety eyes blinking?
