About the service

Restore Reliable Closing With Professional Garage Door Sensor Repair

When a garage door will not close, or reverses just before it reaches the floor, the safety sensors are a common cause. These photo-eyes sit low on each side of the opening and stop the door if their beam is blocked — so when they drift out of alignment or get dirty, the door treats a clear opening as an obstacle.

We realign and clean the sensors, check the wiring back to the opener, and test the safety reverse so the door closes on command and still protects anything in its path.

  • Photo-eyes realigned and cleaned
  • Sensor wiring checked
  • Safety reverse tested
  • Door confirmed closing on command

Off-track repair

My garage door came off the track and I couldn’t get it to close properly. I called for service and they were able to send someone out quickly. The technician got the door back on track, adjusted everything, and tested it several times before leaving. It’s been working perfectly since. Fast, professional service and a very smooth experience overall.

The technician replaced the broken springs, balanced and adjusted the door, and tested everything thoroughly before leaving. The entire process was fast, professional, and hassle-free. My garage door has been working perfectly ever since.

What we repair

Correct The Sensor Faults That Stop Your Garage Door Closing

Most sensor problems come down to alignment, obstruction or wiring. These are the faults we check and correct.

Misaligned photo-eyes

A knocked or drifted sensor breaks the beam and stops the door closing. We realign both eyes so the beam is true again.

Blocked or dirty lenses

Dust, cobwebs or a stray object across a lens reads as an obstruction. We clean the lenses and clear the beam path.

Loose or damaged wiring

A loose terminal or damaged sensor wire interrupts the signal. We check the wiring and connections back to the opener.

Sensor bracket problems

A bent or loose bracket lets the eye drift out of position. We secure the brackets so the alignment holds.

Know the signs

Recognise The Signs Of A Garage Door Sensor Problem

The safety sensors give clear signals when something is wrong, and reading them early saves forcing a door that is trying to protect the opening. Most sensor faults show up the same handful of ways.

If you notice any of the following on your Franklin-area door, the photo-eyes are worth checking.

  • The door starts to close, then stops and reverses
  • The opener light blinks or flashes when you try to close
  • The door only closes if you hold the wall button down
  • A sensor indicator light is off or flickering
  • A sensor sits crooked, knocked or hanging from its bracket

Safe by design

Keep Your Garage Door Safe With Properly Working Sensors

The photo-eyes are a safety feature, not an optional extra — they are what stops a closing door from coming down on a person, a pet or a vehicle. A sensor that is bypassed or ignored removes that protection.

We repair and realign the sensors rather than defeating them, then test that the door reverses reliably when the beam is broken, so the door stays both convenient and safe.

FAQ

Frequently Asked Questions

Why won’t my garage door close all the way?
A door that will not close, or reverses near the floor, is often caused by misaligned or blocked safety sensors. The photo-eyes should be checked and realigned before other causes are considered.
Why is my garage door opener light blinking?
A blinking opener light frequently indicates a safety sensor problem, such as misalignment or a blocked beam. The sensors should be inspected to confirm the cause.
Can dirty sensors stop my garage door from closing?
Yes. Dust or debris on a sensor lens can break the beam and make the door treat a clear opening as blocked. Cleaning and realigning the lenses can restore normal closing.
Is it safe to bypass my garage door sensors?
Bypassing the sensors removes an important safety feature that stops the door closing on people, pets or objects. Repairing and realigning the sensors is the safer approach.
How do you fix garage door sensors that are out of alignment?
We realign both photo-eyes so their beam lines up, clean the lenses, check the wiring, and test the safety reverse to confirm the door closes reliably.
