If The Sensor Lights On Garage Door Go Off

For people who do not know the transmitter has the yellow light and the receiving sensor has the green light.

If the sensor lights on garage door go off.

Inspect each sensor to make sure the green or red power indicator lights are. If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply. Your door control panel is usually on the wall inside your garage. You can choose to press the close button located on the wall of the garage or the remote button.

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. All garage door openers use a sensor light to prevent the door from closing when an object is in its path. Try pressing it again to turn it off. The garage door sensor yellow light and the green light together create a solid illumination.

Raise the garage door using the control button on the garage wall or the remote control unit from a vehicle. If they re turned on in both the sensors then there is no issue with the power supply. 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. If the garage door closes it indicates that the sensors are not functioning.

Sometimes the sensor becomes faulty and needs to be replaced. In this case check the alignment of the opener or better involve a technician. If your door control has multiple functions check the light button on the panel. Look for small led lights on the sensors.

Even though you see lights on your safety sensors does not mean they are aligned properly. One of the sensors sends an infra red beam to the other sensor. 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. 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.

Ensure that the door is open and activate the opener. If this is your situation the first thing you ll want to do is make sure these sensors are properly lined up. 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.
