How the garage door sensors work: Since 1993 garage door manufacturing industry have been introduced anti-entrapment technology as a safety device for garage doors. This innovation was introduced in the form of a sensor. A blinking beam of infrared light is used to transmit and receive signals from one garage door sensor to the other. It is designed to communicate with the garage door opener to tell it that the path is clear and the garage door can be closed completely. Each sensor is placed with small blinking light which shows you that the sensor is in its on and working position. Repositioning or realigning the sensor is a job of making both of the lights to illuminate simultaneously and continuously.
What went wrong with the sensors?
Garage door sensors do not play an important role to lift the garage door. They only concern with the garage door closing process. In case, your garage door refuses to open, you may need to call a garage door repair technician in order to diagnose the main problems. These sensors can become bumped out of alignment which can cause a variety of problems. In many situations, a garage door sensor may lose its electric connection. If the beam of light is damaged, the garage door will not close completely. If there is an electrical malfunction, the garage door may behave normally and close completely, if there is something on the way of the sensor.
How to reset your garage door sensors: The following steps will help you to reset the garage door sensor. First of all, disconnect the power source from a garage door opener or fuse box. Loose the screws which are placed on either side of the garage door to hold the sensors in place. You should slide the metal mounting brackets to adjust the sensor as far as possible. You should use a tap to take an exact measurement, set each sensor up to exactly six inches above the floor, and then retighten the screws and nuts enough so that the mounting brackets will not slide out from the original place on their own.
To ensure that garage door sensors are pointed parallel to each other, you will have to use the stick to simulate the infrared beam. Place a piece of stick from one sensor to the other at the same point on the bottom of the sensor. You should use a measure and keep doing slight adjustments until the stick is level with the floor. Once it’s finished, strongly tighten the screws into their position, check the sensor’s alignment once more, and turn on the power supply.
As mentioned earlier, garage door sensors have a small light that is placed on each side of the door. You can test the functionality of sensors by rolling a softball between them. Notice carefully, if the inner LED lights of sensors do not blink, the garage door needs to be replaced immediately.
Overall, you should clean the garage door sensors periodically to remove the dirt, dust, and moisture which can cause to break the signals. If the garage door is still not responding, there may be a problem with the garage door opener. Don’t hesitate to contact a professional garage door experts.
