What the job involves
What garage door sensor repair involves
Garage door sensor repair deals with the pair of safety eyes mounted on either side of the opening, close to the floor. One sends an invisible beam and the other receives it. If anything breaks the beam while the door is closing, the opener must stop and reverse the door. That is a federal safety requirement for residential openers, and it is why a misaligned sensor makes the door refuse to close.
The usual symptoms are a door that starts down and then goes back up, an opener that blinks its lights or clicks without moving the door, or a door that only closes when you hold the wall button. The causes are ordinary. A sensor gets knocked out of line by a bumped bin or a bicycle. Dust, spider webs or sun glare mask the lens. A wire is pinched at a staple, chewed by a pest, or corroded where it joins the terminal. Sometimes one eye has simply failed. We find which of these it is by testing, not guessing, and we repair or replace only what is faulty.
Our diagnosis
What we check on a sensor problem
Alignment of the two eyes
Each sensor has an indicator light that shows when the beam is received. We aim them at each other and confirm both lights are steady, because a slight twist of a bracket is enough to break the connection.
Lenses and the beam path
Dirt, webs, stored items and bright direct sun on a lens can all interrupt the beam. We clean the lenses and clear the path, and note whether sun angle is the cause.
Wiring along the wall
We follow the low voltage wire from each sensor up to the opener, checking staples, splices, and the terminals on the back of the motor unit. A damaged or shorted wire can make a good sensor seem dead.
The sensors themselves
If one eye has failed, we replace the pair so they match. Mixed or mismatched sensors can cause the same fault to come back.
The opener's response
Finally we test the safety reversal. If the fault turns out to sit in the control board, that becomes an opener repair and we tell you before doing anything further.
How it works
How a sensor repair goes
-
01
Tell us what the door does
Does it close part way and reverse? Do the lights on the opener blink? Do the sensor lights glow, flicker or stay dark? That already narrows the cause.
-
02
We come out and test it
A uniformed technician comes to your home and checks the sensors, their wiring and the opener, testing with the beam rather than assuming.
-
03
We explain what we found and the price
Our technicians explain the problem before starting. You get an upfront quote before any work begins. The price depends on whether it is a realignment, a wire repair or a new pair of sensors.
-
04
We fix it and test the reversal
We realign, rewire or replace, then close the door on a test object to confirm it reverses. Repairs are backed by a parts-and-labor warranty.
A door that will not close is a security problem as well as an annoyance. Tell us what the opener is doing and we will tell you what it likely needs.
