Garage door sensors are essential for keeping your home safe. They stop the door from closing when something is blocking the path, preventing damage or injury. But when a sensor stops working, the door may refuse to close—or it may behave unpredictably. Understanding the garage door sensor repair cost helps homeowners make informed decisions, avoid overpaying, and choose the right technician.
This guide covers the most common sensor problems, average repair costs, factors that influence pricing, and how to know when it’s time to repair or replace your garage door sensors.
⭐ 1. What Do Garage Door Sensors Do?
Garage door sensors—also known as photo-eye sensors—sit on both sides of the door, near the floor. They detect movement or obstacles by sending an invisible infrared beam across the doorway. If something blocks that beam:
- The door will not close
- The opener reverses direction
- A blinking light will appear
When these sensors fail, repair becomes necessary to restore safe operation. That’s when homeowners start researching garage door sensor repair cost to know what to expect.
⭐ 2. Signs Your Garage Door Sensors Need Repair
Here are the most common symptoms:
✔ The garage door won’t close fully
The opener reverses or stops halfway.
✔ Blinking sensor lights
Indicates misalignment or wiring issues.
✔ Door only closes when holding the wall button
A clear sign of sensor malfunction.
✔ Dirty or obstructed lenses
Dust, moisture, or debris can block the beam.
✔ Wiring damage
Humidity, rodents, or age may cause loose or damaged cables.
If you notice any of these problems, it’s time to check the garage door sensor repair cost based on the issue.
