If your sensors or garage door motor is blinking or your door doesn t close it s a sign you could have faulty sensors. If you see that the sender sensor is not yellow and the receiver sensor is not green then this means that your sensors are probably off. Each of the sensors mounted on the garage door has a led light located at the outer side. Sometimes the sensor may be beyond repair due to wear and tear and in such a case your best bet is to replace the garage door sensor with a new one.

Garage door sensors prevent the garage door from closing if there s something in the way. In this case check the alignment of the opener or better involve a technician. Inspect each sensor to make sure the green or red power indicator lights are illuminated. Check the sensors leds.

If both the red source and green sensor lights are on and not blinking then the door mechanism is working properly. Raise the garage door using the control button on the garage wall or the remote control unit from a vehicle. Sometimes the sensor becomes faulty and needs to be replaced. If you own a garage door opener by lift master chamberlain or craftsman you ll notice that the sender sensor will usually shine a yellow light and the receiver sensor will usually shine a green light.

The latest garage door sensors are technologically advanced and even allow you to control the opening and closing through an app on your smartphone. If one or both of the lights are off check the fuses breakers and plugs for problems. The garage door sensor yellow light and the green light together create a solid illumination. All garage door openers use a sensor light to prevent the door from closing when an object is in its path.

To prevent the garage door from injuring someone in the door or damaging an item in the way of the door all models of liftmaster garage door openers come installed with a safety sensor. If you do not see a solid illumination or your garage door is not working the problem is most likely due to the sensors being out of line. Disabling the sensor light on a craftsman garage door opener is only temporary and will render the remote controls useless until you reconnect the sensors.
