Understanding Garage Door Sensors
What Are Garage Door Safety Sensors?
Garage door safety sensors are crucial devices designed to prevent the garage door from closing if there’s an obstruction in the door opening. These sensors, often referred to as garage door safety sensors, are typically located near the floor on either side of the garage door and are essential for a residential garage. They are a standard feature in most automatic garage door systems and are essential for protecting people, pets, and objects from being caught under the door, especially in residential garages.
How Garage Door Sensors Work
Garage door sensors operate using an infrared beam that spans across the door opening. One sensor emits the beam, and the other sensor receives it. When the beam is unbroken, the garage door opener functions normally, allowing you to close the garage door. If an object or person interrupts the beam, the sensors signal the garage door opener to stop and reverse the door, preventing it from closing. This safety mechanism is vital for preventing accidents.
Common Issues with Garage Door Sensors
Here are some common issues that can affect garage door sensors. These issues often manifest as problems with the infrared beam, particularly in the photo eye, and can include:
- Misalignment, where the sensors are not pointing directly at each other, can often be resolved with a garage door sensor sun shield.
- Dirt or debris obstructing the sensor lenses can hinder the effectiveness of the gstb-r stb-bl garage sensor.
Additionally, wiring problems, damaged brackets, or malfunctioning sensors can also lead to problems. Troubleshooting these issues is the first step towards a fix, whether that means cleaning or realigning the sensors, or considering a garage door sensor replacement.
