Why Garage Door Sensors Exist
Your garage door safety sensors (also known as photo-eye sensors or infrared sensors) exist to save lives. These small but vital devices cast an invisible beam across your garage door opening. When something—a person, pet, or object—breaks that beam, the door stops or reverses to prevent injury.
Sensors are sensitive. Small issues can render them useless.
The Most Frequent Sensor Problems We Fix
Misaligned or Blocked Photo-Eye Sensors
A bump can easily knock sensors out of alignment. If the infrared beam can't connect, your opener thinks there's an obstruction and won't close.
Blinking or Non-Responsive Sensor Lights
Signal lights let you know when sensors are communicating. Blinking, dimming, or dark lights signal misalignment, power issues, or sensor damage.
Defective or Rusty Wiring
Water, time, and mechanical stress can degrade the electrical connection between sensors and your opener, causing erratic operation or shutdowns.
Dust, Moisture, or Direct Sunlight Interference
Dirt accumulation, cobwebs, dampness, and even direct sunlight may deflect or saturate the infrared beam and trigger false obstruction alarms.
Faulty Power Connection or Logic Board Failure
The problem isn't always the sensor itself—it may be that the control board on your garage door opener isn't properly interpreting sensor inputs, or there's an issue with power terminal connections.
We diagnose and repair all these problems—ensuring dependable, safe operation every time.
When to Call a Professional
Warning Signs You Shouldn't Ignore:
- Your garage door closes partially, then reverses for no apparent reason
- Sensor lights are not lit, dimmed, or flashing on and off for one or both sensors
- The door won't close unless you hold the wall button continuously
- Sensors function erratically—closing sometimes, not closing other times
- You've cleaned and adjusted sensors yourself but the problem persists
- Your garage door closes and immediately opens back up
- Visible damage to sensor brackets, lenses, or wires
Important: A malfunctioning sensor isn't just inconvenient—it's a safety code violation. Modern garage door systems must be equipped with operating entrapment protection. Operating a door with bypassed or compromised sensors subjects you to legal liability and safety risks.

Our Complete Sensor Repair Process
We don't cut corners. Every service call includes:
Inspection and Diagnosis
We test both sensors, examine all wiring connections, check the opener's logic board, and look for environmental factors affecting performance. You'll receive a clear explanation of what's wrong and why.
Precise Alignment
Using professional tools and methods, we realign photo-eyes to factory specifications. Both sensors must be level and pointing directly at each other for proper beam communication.
Cleaning and Testing
We clean sensor lenses, remove debris from housings, check mounting brackets for stability, and test infrared beam operation.
Safety Compliance Testing
Before we leave, we test for complete UL-325 compliance for auto-reverse and obstruction detection. Your door must respond immediately to obstructions—we test and verify proper safety function.
Full System Demonstration
We'll show you the repair, explain what failed, and answer any questions about maintaining your system going forward.

Frequently Asked Questions About Sensor Repair
Why won't my garage door close all the way?
Typically, one or both sensors are misaligned or blocked. The opener interprets this as an obstacle and won't continue for safety. Our technicians identify the exact cause during inspection and repair it immediately.
Can I realign the sensors myself?
You can make minor adjustments manually, but even slight misalignment will leave the door non-functional. Professional calibration ensures accuracy and safety—and saves you time troubleshooting if DIY attempts fail.
How much does garage door sensor repair cost?
Repair typically costs between $95 and $185, depending on whether realignment, rewiring, or replacement is needed. You'll receive an exact quote before we begin any work—no hidden charges.
Do you repair sensors on older garage doors?
Yes. We carry universal and brand-specific sensor kits that work with both older and newer systems. If you have an older garage door, we can find compatible sensors.
How quickly can you arrive?
We offer same-day service throughout Morris County and surrounding areas. Contact us to schedule your appointment.
My sensors have lights on, but the door still won't close. What's wrong?
Lit sensors indicate power is reaching them, but not necessarily that they're communicating properly. Alignment issues, wiring problems at the opener, or logic board failure may be the culprit. Professional troubleshooting is the fastest path to resolution.
Are sensor repairs covered by warranty?
If your garage door opener is under warranty, sensor repairs may be covered depending on the manufacturer and issue. We can help you navigate warranty claims.
Preventive Maintenance Tips
Between service calls, you can help extend sensor life:
- Wipe sensor lenses regularly with a soft, dry cloth
- Remove stored items and clutter from around sensors
- Check for spider webs on or around sensor housings
- Visually inspect for damage to exposed wiring
- Test the safety system by placing an object in the door's path
- Schedule professional inspections regularly to catch problems before they become major issues
