Testing with a Simple Block

For homeowners eager to ensure the reliability of their garage door sensors, a straightforward and effective method involves the use of a basic block. Let’s walk through the step-by-step process:

  1. Select a Simple Block: Begin by choosing a basic block that can be easily positioned in front of one of the garage door’s photo eyes.
  2. Position the Block: Place the chosen block strategically in the line of sight of the photo eye.
  3. Press the Button: On the wall control unit, press the button to initiate the door closing process.
  4. Listen for the Click: Pay close attention. If the door fails to close, and you hear a distinctive click, it signals that the sensor has successfully detected an obstruction.

Placing the Block on the Ground

Why These Tests Matter

Understanding the significance of the audible clicks during these tests is paramount for homeowners. The clicks are not just sounds; they are assurances that the sensors are functioning as intended. They signify the sensors’ ability to detect obstacles and, consequently, ensure the door’s safe operation.

In the event that any of the safety checks fail, immediate action is imperative. Troubleshooting the issue yourself is a commendable first step, but if challenges persist, reaching out to professionals becomes essential. Garage door’s safety is not a compromise, and timely intervention ensures the ongoing protection of your home.
