Test the sensors ensure that the door is open and activate the opener. The garage door is one of the most prominent parts of our house and they deserve equal care. Look for small led lights on the sensors.

Connect the red probe to the wire going to the sensor and connect the black probe to the ground wire going to the sensor. If the lights are turned on for both sensors then you can rule out a problem with the power supply. The latest garage door sensors are technologically advanced and even allow you to control the opening and closing through an app on your smartphone.
