Garage is one of the most important parts of a property. A garage is protected by the garage door and its sensors. But the color of the sensor may change to indicate about the state of the garage door sensor.
Today, we are going to discuss about why a garage door sensor might start blinking green light and what the solutions are.
Why is my garage door sensor green light blinking?
The green light of the garage sensor can start blinking for several technical reasons. Misaligned garage door sensors can cause the green light to blink. On the other hand, damaged wiring can be also a reason for the blinking green light. A professional electrician can help in such situations.
The green light of the sensor can start blinking along with other colors of light. Let’s discuss in detail about some of the scenarios and their reasons.
Garage door sensor green and red:
First of all, let’s take a look at why green light and red light of garage door sensor might be blinking.
Everything is fine:
Sometimes the green light and red light work together to let you know that the garage door sensors are working properly.
So the green light sensor and red light sensor will blink when they are functioning properly. If the garage door sensors start blinking green light and red light, then it should be taken as a positive sign.
Faulty alignment:
But on the other hand, the green light and the red light of the garage door sensors can start blinking unnaturally when the alignment of the garage door sensors is messed up.
This will require immediate attention of a professional to repair the faulty alignment.
Garage door sensor green and orange:
Secondly, let’s take a look at why green light and orange light of the garage door sensor might be blinking.
Working perfectly:
When the green light and the orange light of the garage door sensor start blinking a little, they are trying to let you know about the functional capability of the sensor. It is very common to see this kind of operational blinking now and again.
Problem with wiring:
The green light and the orange light of the garage door sensor will start blinking excessively if there is something with the wiring of the sensor. In that case, it is wise to contact a professional electrician to find out the exact problem with the wiring.
Problem with alignment:
When the green light sensor and the orange light sensor are out of sync, it can cause the blinking issue. The green light sensor and the orange light sensor need to be realigned to solve the issue of blinking light.
Garage door sensor green and yellow:
Thirdly, let’s take a look at why green light and yellow light of the garage door sensor might be blinking.
Good condition:
Most of the times, the green light and the yellow light of the garage door sensor will blink together to indicate at the good condition of the sensor.
The normal blinking rate of the green light and the yellow light should not be taken as a sign of weakness.
Disrupt in the transmission:
Transmission of infrared beam takes place between the green light sensor and the yellow light sensor.
When the transmission of the beam gets disrupted for some reason, then the green light and the yellow light of the sensor starts blinking excessively which is not a good sign at all.
Alignment issue:
The position of the green light sensor and the yellow light sensor can get displaced for some reason. This will cause alignment issue which makes the green light and the yellow blink more than expected.
Are garage door sensors supposed to be green?
All the garage door sensors are not supposed to be green. There are lights of different colors and functions on a garage door sensor.
For example, green light of the garage door sensor gives you the signal about the functionality of the sensor. When the green light of the garage door sensor is on, your garage door sensor is working accurately.
However, there are also other colors of light on the garage door sensor. Red light of the garage door sensor gives you an idea about the alignment of the sensor.
If the red light is on, then you can be sure about the accurate alignment of the sensors. Red light indicates at the perfect alignment of the garage door sensors.
On the other hand, yellow light of the sensor comes on to let you know about the transmission of infrared beam between the sensors. The infrared beam sent by the yellow light sensor is received by the green light sensor.
Finally, the orange light of the sensor signals you about the state of the wiring system. If the orange light of the sensor begins blinking, it means that there is something wrong with the wiring of the garage door sensor.
So all the different colors of sensors are unique and all of them are not supposed to be green. Only the green light sensor will be green and other will retain their color in any given situation.
What does flashing green light mean on garage door sensor?
It can be very difficult to find out what flashing green light means on garage door sensor. Let’s discuss in detail about the possibilities.
Possible misalignment:
The primary reason why your green light sensor might be flashing is because the garage door sensors might be out of alignment. There has to be a perfect alignment between the garage door sensors in order for the sensors to work together.
If one of the sensors goes out of alignment, then the green light sensor along with other sensors might start flashing all of a sudden. This issue should not be taken lightly and a professional electrical needs to be contacted immediately.
Possible wiring issue:
Another major reason why your garage door sensor might be blinking green light is that there might be some problem with the wiring of the sensors.
If the wiring of the sensors gets damaged due to some reason, then the green light sensor along with other sensors will start flashing to let you about the dire situation.
The help of a professional electrician should be sought when this happens. Wiring issue is something that should not be taken lightly as it can cause permanent damage to your garage door sensors.
Possible transmission issue:
Another possible cause of flashing green light can happen due to a problem with the transmission of infrared beam. Transmission of infrared beam keeps taking place between the garage door sensors for operational purposes.
When the transmission of infrared beam gets interrupted, the green light of the garage door sensor might start flashing to give you a signal about the problem.
Permanent damage:
If the garage door sensors become damaged due to any external force, then the green light of the sensor might start flashing.
It is a clear indicator that something is wrong with the wellbeing of your garage door sensor and it needs immediate attention. When the garage door sensor is permanently damaged, you will need to replace it instead of repairing it.
How do I reset my garage door sensors green light?
Resetting the garage door sensor might seem like a difficult task if you have no prior experience regarding the matter. However, there are some steps and methods you can follow to accomplish the task. Let’s discuss in detail about some of them.
Inspect the wiring:
First of all, you will have to check the wiring of your garage door sensors if the green light keeps flashing. If there is a loose connection in the wiring system, then you will need to correct it. But damaged wires have to be replaced in order for this to work.
Check the alignment:
You will need to check the alignment of your garage door sensors if there is nothing wrong with the wiring.
Correcting the inaccurate alignment will stop the green light from flashing and will reset it. Resetting the alignment is one of the basic ways of getting rid of flashing green light.
Reset it manually:
Another way to reset the green light of the garage door sensor is by resetting the sensor manually.
In order to that, you will be required to turn the switch light on and off several times to reset the garage door sensor. The green light turning off will signal you about the success of the reset process.
Final Thoughts
Green light of the garage door sensor can start blinking when the sensors go out of alignment. The green light can also start blinking because of an interruption in the transmission of infrared beam. Sometimes resetting the garage door sensor can stop the blinking of green light.
