Jul 18, 2025Understanding Garage Door Sensors: How Garage Door Specialists of Neenah Keep You Safe
Ever had your garage door stop unexpectedly or refuse to close, leaving you wondering what went wrong? Chances are, your garage door sensors were doing exactly what they were designed to do. While they may seem like a small component, sensors are the backbone of your garage door’s safety system.
At Garage Door Specialists of Neenah, we understand how essential sensor reliability is to the overall safety and functionality of your garage door system. Whether you’re experiencing malfunctions or just want to ensure everything is working properly, we’re here to explain how these devices work, why they matter, and how we make sure yours are always performing at their best.
What Are Garage Door Sensors and How Do They Work? Garage door sensors are safety-critical components installed on both sides of your garage door, typically no more than six inches off the ground. These infrared sensors communicate with each other by sending an invisible beam across the width of your garage door opening.
Here are the two key parts:
- Emitter Sensor (Sender): Projects the invisible infrared beam.
- Receiver Sensor: Detects the beam and sends a signal to the opener.
If the beam is interrupted by anything, a car tire, a child, or even a broom handle, the sensors signal the garage door opener to immediately stop or reverse. This ensures your garage door doesn’t close on objects, people, or pets.
These sensors are required on all automatic garage doors in compliance with federal regulations such as the UL 325 safety standard.
Why Garage Door Sensors Are a Safety Must-Have While they may not be flashy, garage door sensors are essential for home safety and peace of mind. Here’s why they matter:
- Preventing Accidents: Sensors stop the door from closing on people, pets, or vehicles.
- Protecting Your Property: Avoid costly damage to cars, bikes, and equipment stored in the garage.
- Improving Security: Ensures the door closes completely and won’t be left ajar due to malfunction.
- Compliance with Safety Codes: Ensures your garage door opener meets legal safety standards.
In a space like a garage that often sees daily use, these fail-safe features are essential.
