How to Install a Garage Door Sensor

Installing a garage door sensor is an important safety measure to ensure that your garage door operates properly and does not pose a danger to people or objects in its path. Here is a step-by-step guide to installing a garage door sensor:

Step 1: Turn off the power to the garage door opener. This can typically be done by unplugging the unit or turning off the circuit breaker that powers it.

Step 2: Locate the sensor brackets. These are typically small metal brackets that attach to the garage door tracks on either side of the door.

Step 3: Attach the brackets to the tracks using the provided screws. Make sure they are securely fastened and level with each other.

Step 4: Mount the sensors onto the brackets. The sensors should be placed facing each other, with one on the left side of the door and one on the right. They should be mounted at the same height and level with each other.

Step 5: Connect the wires from the sensors to the garage door opener. This will typically involve connecting the wires to the back of the opener unit using the provided wire connectors.

Step 6: Test the sensors. With the power still turned off, activate the garage door opener and slowly lower the door. The sensors should detect the door and stop it from closing if there is an obstruction in its path.

Step 7: Adjust the sensors if necessary. If the door does not stop when an obstruction is detected, adjust the sensors until they are properly aligned and able to detect the door.

Step 8: Turn the power back on to the garage door opener and test the sensors again to ensure they are working properly.

By following these steps, you can install a garage door sensor to help ensure the safety of your garage door and prevent accidents or damage.
