How to Check Your Garage Door Safety Sensors: A Comprehensive Guide


Your garage door is one of the heaviest moving objects in your house and it can cause serious injury or even death if it malfunctions. That is why it is important to ensure that your garage door is safe and secure to operate. One of the major components that you should check regularly is the safety sensors. Safety sensors are located on both sides of the garage door and its function is to detect obstacles and prevent the garage door from closing if something interrupts their line of sight.

Step 1: Remove Obstacles


Before beginning any Check-up on your garage door safety sensors, it is important to remove all the obstacles around the door. Make sure that there are no lawn tools, boxes or any other objects that are in the way of the garage door’s path. This will help you to identify any potential problems when testing the safety sensors.


Step 2: Test the Sensors


Testing the sensors is a straightforward process. First, you need to make sure that the sensors are aligned, facing each other, and unobstructed. Then, close the garage door using the remote control, and as it’s closing, pass a long object (like a broom) in front of the sensors while the garage door is closing. If the sensors are working properly, the garage door should stop and reverse immediately in response to the object.

Step 3: Clean the Sensors

If the garage door does not reverse when you passed an object in front of the sensors, there is a high chance that the sensors are dirty. Dirt, cobwebs, and even condensation can accumulate on the sensors and disrupt their function. It is recommended that you wipe the sensors with a soft cloth and a little bit of cleaning solution. Make sure to clean them gently and avoid using harsh chemicals or materials.

Step 4: Check the Wiring

A damaged wire can affect the function of the garage door sensors. Check all the wiring between the sensors and the motor to make sure there is no damage, fraying, or any other visible signs of wear and tear. If you find any damaged wires, contact a professional garage door technician.

Step 5: Maintenance Checks

It is important to perform maintenance checks periodically to ensure the sensors and other components of your garage door are working properly. Check the sensors for dirt and grime, and clean them as necessary. Also, inspect the sensors for any signs of wear and tear, and replace them if needed. Keeping your garage door in good working condition is the best way to ensure the safety of your family and property.
