Do Garage Door Sensors Ever Go Bad in Sunnyvale, CA?

If you’re a homeowner in Sunnyvale, CA, dealing with garage door issues can be quite a hassle, especially if you’re unsure what the problem is. A common question we hear at GoPro Garage Doors is, “Do garage door sensors ever go bad?” The short answer is yes, they can.

In this blog, we’ll dive deeper into this topic and explain why garage door sensor issues occur, how to identify them, and what you can do to fix them.

Garage Door Sensors — What Are They? 

First, let’s understand what garage door sensors are. These sensors are a critical safety feature, designed to prevent the door from closing if an object or person is in its path. They usually come in pairs, installed on either side of the door, close to the ground. Each sensor emits an invisible beam to its counterpart; if this beam is interrupted, it signals the garage door opener to stop the door from closing.

Why Do Garage Door Sensors Fail?

Why Do Garage Door Sensors Fail?

Misalignment: Over time, sensors can become misaligned, often due to physical disturbances like accidental bumps or vibrations from the garage door’s operation. This misalignment is a common reason for sensor malfunction in Sunnyvale, CA.

Dirt and Debris: The sunny and sometimes dusty climate of Sunnyvale can lead to dirt accumulation on the sensors, obstructing the beam. Regular cleaning is necessary to prevent this.

Wiring Issues: The wiring that connects the sensors to the garage door opener can become frayed or damaged. This can happen due to age, environmental factors, or pests.

Wear and Tear: Like any other equipment, sensors are subject to wear and tear. Over years of use, the components can degrade, leading to failure.

Sunlight Interference: In sunny regions like Sunnyvale, direct sunlight can sometimes interfere with the sensors’ infrared beam, causing them to malfunction.

Identifying Sensor Issues

If your garage door isn’t closing properly, or reverses immediately after starting to close, it could be a sign of sensor issues. Here’s how to identify and troubleshoot:

  • Check for Obstructions: Ensure nothing is blocking the sensors’ path.
  • Inspect for Alignment: Look at the LED lights on the sensors. Most models have lights that indicate whether they are properly aligned.
  • Clean the Sensors: Wipe the lenses gently with a clean cloth.
  • Examine the Wiring: Check for any visible damage to the wires.

Fixing the Problem

In many cases, realigning or cleaning the sensors can resolve the issue. However, if the problem persists, it could indicate a need for professional attention. For reliable and efficient garage door repair in Sunnyvale, CA, it’s best to call experts like GoPro Garage Doors.
