Fix safety sensors so your door closes properly. Same-day service available.
Garage Door Repair Guys provides garage door sensor repair and replacement for homeowners throughout Sarasota County, Florida, including Sarasota, Venice, Bradenton, North Port, Englewood, Osprey, Nokomis, Longboat Key, and Siesta Key. Modern garage doors use photo eye sensors near the floor to prevent the door from closing on people, pets, or vehicles. When sensors malfunction or go out of alignment, the door may refuse to close or reverse unexpectedly. With 15+ years of local experience, our technicians diagnose wiring and alignment issues, clean and reposition sensors, or install new units when needed. We ensure your door meets safety standards and works reliably in Florida's humid, coastal conditions.
Garage Door Won't Close? Sensor Problems Fixed Today.
Blinking sensor lights, doors that reverse immediately, and doors that only close when you hold the button are usually sensor issues. Garage Door Repair Guys can fix them same-day.
How Garage Door Safety Sensors Work
- Sensors are mounted near the floor on each side of the door
- One sends an infrared beam; the other receives it
- If anything breaks the beam, the door reverses or will not close
- Sensors must be aligned, clean, and properly wired
Florida dust, insects, and humidity can interfere with sensor operation, making regular inspection important.
Common Sensor Problems
- Blinking lights – One or both sensor lights are off or blinking
- Door reverses – Door begins to close, then immediately reverses
- Constant pressure required – Door only closes when you press and hold the wall button
- Misalignment – Sensors are visibly misaligned or hanging loose
- Wiring damage – Wires are damaged, chewed, or corroded
- Water damage – Sensors flooded or water-damaged after heavy rain
Our technicians find whether the issue is alignment, wiring, power, or sensor failure.
Our Garage Door Sensor Repair Process
- Visual Inspection & Cleaning – Check alignment, mounting brackets, and LED indicators; clean lenses of dust, spider webs, and debris
- Alignment & Testing – Adjust sensors so they point directly at each other; test door operation to see if the issue resolves
- Wiring & Power Check – Inspect wires for damage or corrosion; test voltage at the sensor terminals
- Sensor Replacement (If Needed) – Install new compatible sensors for your opener brand; route and secure wiring above ground to avoid moisture
- Final Safety Tests – Confirm door reverses when beam is blocked; ensure door can close normally with remote and wall button

Garage Door Sensor Repair FAQ
Common questions about sensor repair in Sarasota County.
This is usually a sign that the safety sensors are not working correctly. The opener enters a "constant pressure" mode as a safety backup. Causes include dirty lenses, misalignment, damaged wires, or failed sensors. Proper repair restores normal one-touch closing.
Yes. Direct sunlight at certain angles can interfere with sensor beams on some systems, especially in bright Florida conditions. Shielding, slight sensor repositioning, or upgraded sensors often solve the problem. Our technicians are familiar with local lighting patterns in Sarasota County.
Dirty sensors often have visible dust or spider webs, and cleaning them may restore function. If LED lights do not behave correctly after cleaning and realigning, or the door still will not close, the sensors or wiring may be faulty and need professional diagnosis.
Sensor replacement in Sarasota County typically costs $150-$250 for a pair, including parts, wiring connection, alignment, and testing. If wiring needs repair or the opener has additional safety issues, total cost may be slightly higher.
Bypassing safety sensors is not recommended and is a code and safety violation. Sensors prevent the door from closing on people, pets, and vehicles. Instead of bypassing, have faulty sensors professionally repaired or replaced to restore safe operation.
Sensors often last 10-15 years, but Florida's humidity, insects, and occasional flooding can shorten lifespan. Regular cleaning and ensuring wires stay dry and protected help sensors last longer and function reliably.
