Every other garage door opener that has been made after 1993 are equipped with some form of sensor or the other. The entire working principle is based on the idea of infrared beams. Generally, the error of garage door won’t close light blinks occurs when there is something restricting the path of the sensors. Or, in general, the sensor gets out of alignment. You can’t close the door under these circumstances.
Our first recommendation goes with checking whether the sensors are properly aligned or not. In fact, the majority of the time, you can fix the problem within a matter of minutes.
So, the sole purpose of this article is to make you aware of the various ways in which you can troubleshoot your garage door opener.
The Sensors are Completely Fine
Sometimes you might find that there is actually nothing wrong with the sensor. In fact, they are properly aligned, and nothing is within their way as well. Under such circumstances, you need to trace back to the wirings that lead to the sensors. You can always cross-check to find the defective ones. That being said, sometimes even connecting and disconnecting the wirings can make them work once again.
Diving Deeper into Further Troubleshooting
As discussed earlier, there are two sections of a garage door sensor. You can find the receiver as well as the sender. Now the sensor that sends the signal actually comes with yellow service light. While on the receiver end, the light is generally green in color. Now, even if one of the light is not showing up, chances are they are misaligned.
Checking the back of the motor unit can actually say a lot about the sensors. The service board comes with its own set of sensor lights as well.
You can understand the sensor indicated in the following ways:
For Older Units:
- One blink indicates disconnected sensor wiring
- Two blinks indicate the shorted wire
- Three blinks indicate misaligned sensors
For Newer Models:
- One up blink and one down blink indicates disconnected sensor wiring
- One up blink and two down blink indicates shorted wires
- One up blink and four down blink indicates misaligned sensors
- Four up blink and six down blink includes temporary obstruction
It is imperative to understand that if both the sensors are working properly but still your garage door is not closing; chances are you have a faulty sensor in hand. Now, there is no point in denying that garage door sensors require replacement like every other electronic equipment as well. So, once you change them, you are always good to go.
