How it works
Step 1
Read code
Opener blink code tells us if it's alignment, wiring, or a dead sensor.
Step 2
Align / replace
Brackets adjusted, lenses cleaned, or sensors swapped.
Step 3
Re-wire
Damaged sensor wire re-run end-to-end if continuity fails.
Step 4
Test
Three close cycles plus object-in-path safety test.
How safety sensors work
Two photo-eye sensors mounted 6 inches off the floor on each side of the door create an infrared beam across the opening. If anything breaks that beam, the opener refuses to close — or reverses if it's already closing. Required by federal law since 1993 on every residential opener.
Why your door suddenly stopped closing
Sensors don't fail dramatically — they drift. A bracket loosens over time, a bag bumps one in passing, the sun's angle changes seasonally and blasts the receiver, or a wire staple finally cuts through after a decade outdoors. We diagnose the actual cause and fix it once.
Frequently asked questions
Why won't my garage door close?+
9 out of 10 times it's the safety sensors — knocked out of alignment, lenses dirty, sun glare on the receiver, or a wire cut by a weed-whacker. The opener refuses to close if the sensors don't agree, which is exactly what it's supposed to do.
What do the sensor lights mean?+
One LED is the sender (usually steady amber/yellow), the other is the receiver (usually steady green). If the receiver is off or blinking, alignment is off or the wire is bad. If both are off, the wire run lost power.
Can I just bypass the safety sensors?+
Don't. They're federally required since 1993 and they're what prevents the door from crushing a child, pet, or vehicle. A 30-minute alignment fix is cheaper than the alternative.
Do sensor wires go bad?+
Yes — UV-exposed bell wire stapled to the wall gets brittle and breaks at the staple. Weed-whackers cut them at the bottom. Lawn equipment yanks the sensor and breaks the wire inside the insulation. We re-run the wire when we find it.
How long does sensor repair take?+
30–60 minutes for alignment and cleaning. 60–90 minutes if we have to re-run a wire or replace a sensor.

“Replaced a builder-grade door on our Palmer Ranch home with a Haas hurricane-rated unit. Crew was on time, clean, and walked me through the new LiftMaster app.”

“After Ian we needed a full replacement. 941 handled the insurance paperwork and had the new door installed faster than any other quote we got. Highly recommend.”

“Opener died at 9pm. They picked up the phone, set me up with a new LiftMaster the next morning. Belt drive — you can't even hear it run.”
Jeff D.

“Cables were frayed from salt air. Tech showed me the damage, gave me a flat-rate price, done in an hour. Will only call 941 from now on.”

“Backed into my own door. They color-matched a single panel instead of selling me a whole door. Saved me thousands. Real pros.”
