Is your garage door opener not functioning fine? Are you confused between sensor lights? What color should the lights be on garage door sensors? If your garage door opener is not working, the problem might be with safety sensors. You can fix this issue. You will have to observe the blinking opener lights. The blinking light codes will indicate that safety sensors are either out of the alignment or are blocked.
What Color Should the Lights Be On Garage Door Sensors – What does it mean when one garage door sensor is green and one is red?
There are many garage door tips to remember, but this article will specifically
focus on garage door sensors. The safety sensors feature an indiscernible ray of infrared lights. These lights will detect any obstruction on your garage door path. These sensors will not allow your garage door to be closed when some obstruction is there.
How to Understand the Code Errors
If you do not find anything on the path, you can simply check the alignment. Garage door experts say remember that all the safety sensors come with indicator light. The sending sensor features a yellow light and the receiving sensor will have a green light. So, you will have to first make sure that the yellow light on the sending sensor is on and then you can check the green receiving light. However, whenever the green light is off, you need to realign the safety sensors. Once the light turns green, it will start working.
Now you might find the answer to what should be the color of sensor lights to ensure the proper functioning of your garage door opener. The sending lights should be yellow and the receiving lights should be green. When none of them work, your garage door opener will not work. To fix this issue, you will have to check the alignment. Also, you need to check the LED troubleshooting light on your motor unit to find out any error. Check the codes on the motor to know the exact cause.
- If there is one link on the motor light, this is the indication that the sensor wires are not connected.
- When you notice two blinks, this is the signal that the sensor wires of the opener are shorted.
- When the blinks are four, this is the sign that the sensor wires are not properly aligned.
However, the error code might vary depending on the model of the door opener you are using. If you have newer-chain drive models or belt drive
garage door opener models, you can notice the following error codes.
- One blink up and one blink down: This is the sign that wires are broken or sensors are not installed properly.
- One Blink up and two blinks down: This error code shows that wires are reversed and shorted.
- One blink up and four blinks down: This error code proves an obstructed or misaligned sensor.
- Four blinks up and six blinks down: This error shows temporary misalignment and obstruction.
Whether your garage door is squeaking loudly or your sensors are giving error codes, it is important to solve the problem as soon as possible. What color should the lights be on garage door sensors? The sending light should be yellow and the receiving light should be green. Also, you will have to check the light on the motor unit to know the exact cause of the problem. First, know the cause and then only you can fix it on your own or by professionals.
