Photo-Eye Sensors — The #1 Reason Doors Won’t Close
The fix is rarely complicated, but it does need someone who knows what to check first. We diagnose in minutes, not hours: alignment, lens cleaning, wiring, or sensor replacement — in that order. Most homeowners are back to a working door in under an hour.
What’s Included in Every Repair:
We test both photo-eye sensors with a meter, check the LED status, and confirm whether it’s alignment, wiring, or a failed unit.
Most non-closing doors just need the sensors realigned. We adjust both eyes until the steady LEDs confirm a clean beam.
Spider webs, dust, and Florida sun glare are sneaky causes of failed sensor signals. We clean lenses and shield from direct sunlight.
We check the bell wire from each sensor up to the opener motor for nicks, breaks, staple damage, or rodent chew — the second most common cause of failure.
If a sensor has failed, we replace with the correct OEM-compatible pair for your opener brand — LiftMaster, Chamberlain, Genie, Craftsman, all stocked on the truck.
Bent or cracked sensor brackets cause constant misalignment. We straighten or replace with new brackets so the realignment actually holds.
Federally required: the door must reverse before hitting a 1.5″ obstruction. We test with a 2×4 board before we leave.
Every remote, wall button, and keypad tested. Door cycled 3+ times to confirm the fix is permanent, not a fluke.
4 Sensor Problems We Fix Daily
Misaligned Sensors
One sensor LED is off or blinking. Got bumped by a bike, broom, or kid? Realignment is usually all you need — takes 10–15 minutes.
Lens / Sun Glare
Florida afternoon sun blasts the sensor lens and confuses the photo-eye. Fixed with a clean and a small sun shield — not a replacement.
Bell Wire Damage
Staples through the wire, rodent chew, or a nick from a screw. The opener gets no signal and the door stops closing.
Replace Sensor Pair
LED won’t light up at all even with proper power and clean wires. The sensor itself is dead — full pair replacement is the right call.
Our Sensor Repair Process
Diagnose by Symptom
You tell us what the door does and what the sensor LEDs are showing — off, blinking, or steady. We narrow it to alignment, wiring, or sensor failure before we even arrive. No guesswork on-site.
Fix the Cheapest Cause First
Most repairs are alignment or lens cleaning. We always check those first. If the sensors test bad with a meter, we pull the right OEM-compatible pair from the truck and replace.
Auto-Reverse Safety Test
A 1.5″ obstruction (we use a 2×4) goes in the door path. The door must reverse the moment it touches. We don’t leave until that test passes — that’s the federal safety code.
Why Choose Us for Sensor Repair?
🔨 We Fix the Cheapest Cause First — Not the Most Expensive.
“A lot of techs walk in and quote a full sensor replacement before they even check alignment. We test, clean, and realign first — and only replace if the sensors actually fail the meter test.”

WHAT HOMEOWNERS SAY ABOUT OUR INSTALLER
Sensor Repair Questions Answered
Why won’t my garage door close?
In 9 out of 10 cases, the photo-eye sensors at the bottom of your door are misaligned, dirty, or have a damaged wire. The opener light usually flashes 10 times when this happens — that’s the signal that the safety beam is broken. Less common causes are a stuck wall button, a bad opener logic board, or a tripped close-force limit.
What does the LED on the sensor mean?
Each sensor has a small LED. Sending sensor (usually amber/yellow) should be steady when powered. Receiving sensor (usually green) should be steady when it sees the sender’s beam. If green is off or blinking, the beam is broken — either alignment, dirty lens, sun glare, or wiring. If amber is off, you have a wiring or power problem at that sensor.
Can I realign garage door sensors myself?
Yes, sometimes. Loosen the wing nuts on each bracket, point both sensors at each other, and tighten when both LEDs go steady. If the LEDs still won’t light up, or the door still won’t close after alignment, the issue is likely wiring or a failed sensor. Our diagnosis is $75 and includes the realignment if that’s all that’s needed.
How much does sensor repair cost?
Realignment: $75–$95. Lens clean + sun shield: $75–$110. Bell wire repair: $110–$165. Full sensor pair replacement: $140–$210. All pricing is flat-rate and includes the federal-code auto-reverse safety test. Free estimate, no obligation.
How long does sensor repair take?
Realignment is 10–15 minutes. Lens cleaning and sun shield install is about 20 minutes. Wire repair is 30–45 minutes. A full sensor pair replacement, including new brackets and auto-reverse testing, takes 60–75 minutes. We arrive with everything stocked, so it’s always a single visit.
Do you repair sensors on all opener brands?
Yes — LiftMaster, Chamberlain, Genie, Craftsman, Linear, Sears, Liftmaster Elite, and any other brand we’ve seen on a Broward County opener. We carry universal-fit sensors that work with any brand, plus OEM-spec replacements for the brand-specific units.
