If the sensor lights on garage door go off.

Look for small led lights on the sensors. While the overhead light built into your garage door will prove useful at night or when you re searching for something in your garage it s important to know how to turn your light off. For people who do not know the transmitter has the yellow light and the receiving sensor has the green light. You can choose to press the close button located on the wall of the garage or the remote button.

Sometimes the sensor becomes faulty and needs to be replaced. Your door control panel is usually on the wall inside your garage. If they re turned on in both the sensors then there is no issue with the power supply. If your door control has multiple functions check the light button on the panel.

If your craftsman garage door opener fails to close the door properly you may need to disable the sensor light temporarily until you can replace the sensors. Ensure that the door is open and activate the opener. 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. Sometimes the light switch button is accidentally activated which causes the light to stay on.

If this is your situation the first thing you ll want to do is make sure these sensors are properly lined up. One of the sensors sends an infra red beam to the other sensor. If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply. If any of these sensors should happen to get bumped or misaligned the infra red beam would be thrown off and the garage door won t go down.

All garage door openers use a sensor light to prevent the door from closing when an object is in its path. In this case check the alignment of the opener or better involve a technician. If your liftmaster door opener light is blinking stays on or won t turn off you can simply access the smart control panel to change the setting. If the sending sensor is slightly off it can cause the connection with the receiving sensor to be off by several inches over the span of a 16 foot wide garage door.

Try pressing it again to turn it off. A common cause of a malfunctioning garage door sensor is lack of power supply. If the garage door closes it indicates that the sensors are not functioning.
