Need garage door safety sensor repair in New York? New York Garage Door Repair handles garage door safety sensor repair across New York, NY and the towns around it — diagnosed first, with the part named before the work is priced.
Garage Door Safety Sensor Repair done straight
We work out which part has actually failed before anyone quotes a repair, we say so when the fix is something you can do yourself for nothing, and we leave the door passing both safety reversal tests.
- The part is named first — you see the failed part on your own door before you see a price for it.
- The free checks come first — misaligned safety sensors, a thrown manual lock or a trolley on the emergency release, talked through on the phone at no charge.
- A spring is a spring — a broken one is not a reason to quote you a new door or a new opener.
- Tested before we leave — hand balance, contact reversal and the photo-eye reversal, and we show you how to repeat them.
What the two eyes near the floor are for
Every garage door opener sold since 1993 has to stop and reverse a closing door without touching anything, and the photo eyes are how it does it. Two small units sit on the tracks about six inches off the floor; one sends an infrared beam across the opening and the other receives it. Break the beam while the door is coming down and the door goes back up. When the eyes are unhappy the opener refuses to close at all, usually starting down an inch and returning, and on most makes the light on the motor head blinks while it happens. That blink is not a fault code for a broken opener. It is the opener saying it cannot see its own safety circuit, and it is the single most common reason New York Garage Door Repair gets called about a door that will not close.
Why they stop seeing each other
Most of the time nothing has broken. A bike, a bin or a snow shovel has nudged one bracket out of line, or a lens has picked up enough dust or cobweb to weaken the beam. Direct low sun straight into the receiving eye will do it too, which is why some doors fail only in the late afternoon and behave perfectly the rest of the day. Where something has genuinely failed it is usually the wiring rather than the sensor: the wire runs along the wall at ankle height, and it gets stapled through during a garage tidy-up, nicked by a strimmer, or chewed by a rodent. We check the alignment and the lenses first, then the wire, and only then talk about replacing the pair — and if the fix turns out to be the two-minute one, we would rather tell you on the phone than drive out for it.
