The root cause for many reported cases of garage doors not opening and closing is the garage door sensor. Sensors send a signal to the opposite sensor via an invisible beam. If the beam is broken, the door will not open or close. This functionality is what prevents the door from closing when it senses that a person or an object are in its way and it is a method of preventing garage door accidents.
Due to the sensor sensitivity, the sensors may become hot, dirty or knocked out of alignment which will also break the beam alignment and prevent a garage door from opening and closing.
When the beam is broken, check the following.
- Make sure that there are no objects blocking the sensor beam. If an object is blocking the beam, the door will not close.
- Ensure the sensors are clean. Dirt will break the sensor alignment beam.
- Make sure that the sensor is in alignment. Sensor lights will blink when the sensor is taken out of alignment. Adjust the sensor by moving it slowly towards the other sensor until the light stops blinking.
If you are unable to align the sensor, call a garage door professional.
