Here at Neighborhood Garage Door Repair, one of our customer’s most asked questions is “why does my garage door sensor have a yellow light?” More often than not, our customers believe it is because something is wrong with their door. Fortunately, every one of them has one yellow light, but there are some things you need to look out for.
Why Is the Garage Door Sensor Yellow?
On most garage door opener models, you will notice two different lights, one green and one yellow. The yellow (or in some cases amber) light is the sending sensor. This device will permanently light yellow to let you know it is sending a signal.
The green light is the receiving sensor. This one receives a signal from the sending sensor, allowing the garage door to open or close or interrupt the process if something is in the way. The receiving will light green once it is aligned properly with the sending.
If you’re having garage door issues, and notice something other than the standard green and yellow lights on your opener, then there may be something wrong with your sensors. Typically, these issues can be solved by simply realigning the sensors. Sometimes, however, they may require professional assistance.
Here are some signs that something is wrong with your sensors:
No Green Light
If the receiving sensor is not transmitting a green light check the alignment of your sensors. More often than not, this is due to the receiving sensor not receiving a signal from the sending sensor. Make sure that the two sensors are aligned with one another and there are no objects obstructing their line of view.
The Receiver Sensor Is Blinking
This is another sign that the sensors may not be aligned properly or that one of the sensor eyes are dirty. A common mistake amongst homeowners is failing to regularly clean the sending receivers sending eye. If dirty, this can lead to the receiver sensor failing to pick up a signal.
There Are Two Yellow Lights
If both sensors are lighting up yellow then you have two receiving sensors. This is an uncommon occurrence but we have seen it happen. If this is the case, it’s best to contact your garage door manufacturer to report the issue.
