Replace Your Old Sensors

Garage Door Opener Blinking Light / Sensor Fix| Garage Tec Garage Door Repair Richardson

If youre still seeing the yellow light on your garage door sensor even after cleaning the lenses, realigning them, reconnecting/replacing sensor wiring, moving objects out of the way AND contacting support, then its time to buy new sensors.

There are countless possible reasons your old sensors stopped working time, overuse, exposure to harsh weather, etc. Regardless of the reason, your old sensors need to be replaced.

To start, go online, or to your nearest home improvement store and buy a replacement pair. Make sure the new sensors are compatible with your model garage door opener.

Once you have your new, compatible garage door sensors, youll need to install them. To install your new sensors, follow these steps.

Door track installation:

  • Slide the curved arms of the sensor bracket around the edge of the door track. Snap into place so that the sensor bracket is flush against the track.
  • Slide the carriage blot into the slot on each sensor.
  • Insert the bolt through the hold in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket.
  • Installation without pre-wiring:

  • Run the wire from both sensors to the garage door opener. Attach the wire to the wall and ceiling with the staples.
  • Strip 7/16inch of insulation from each set of wires. Separate the wires. Twist the white wires together. Twist the white/black wires together.
  • Pre-wired installation:

    Possible Causes Of Garage Door Sensors Malfunction

    Just like any other highly programmed component, garage door sensors can get faulty. Here are common causes of garage door sensors problems:

    • Lack of power supply- Garage door sensors are an electric component that requires a power supply to function. A power supply problem can be a power cut or faulty power cables/sockets on both or one of the sensors.
    • Dust on your lenses- If your garage is situated in a highly dusty area, the dust may pile up on your lenses, leading to a malfunction. The dust usually blocks the infrared beam emitted by the two sensors.
    • Moisture- If there is a sprinkler near your garage or you live in areas that experience heavy rainfall, moisture could accumulate on your lenses and block them from functioning correctly.
    • Misalignment- Garage door sensors will only work if they are perfectly aligned. If one sensor is moved out of place, the infrared beam will not reach the other sensor, which will render the entire system faulty.
    • General wear and tear- If you have used your garage door sensors for an extended period , general wear and tear may be the cause of the malfunction.

    Damaged Photo Eye Wiring

    The wiring of the photo eye supplies it with the electricity it needs to function. If the wire is compromised, the sensor wont work.

    As such, you need to be on the lookout for these danger signs:

    • Frayed or corroded cords
    • Loose connections
    • Cracked, pinched, or pierced wire insulation

    Addressing this issue can be tricky, but it can be done. In fact, heres a step-by-step video on how to replace the wiring by yourself.

    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.

    How To Fix Yellow Light On Garage Door Sensor

    A yellow light on your garage door sensor indicates that your safety reverse sensors are out of alignment. Your garage door will not close until they are fixed. Start by cleaning the lenses on both sensors and then adjust each sensor so that they line up perfectly with one-another.

    Your garage door sensors are most often found a few inches off of the ground, one on each side of your garage door.

    These sensors use something called a photo-eye system. Simply put, they shoot an invisible, infrared beam from side of your garage door to the other.

    When you press the remote control that closes your garage door, a signal is sent to these sensors. Their primary purpose is to prevent your garage door from closing on something, or someone.

    Your garage door only opens if the invisible infrared beam running across your garage door remains uninterrupted. But occasionally these sensors malfunction.

    The key signs of a malfunctioning sensor is of course the yellow sensor light and the garage door not closing, or attempting to close and then quickly opening again. Followed by a flashing light from your overhead control box.

    Blocked Or Dirty Sensors

    You may also see the red blinking light if something is blocking the sensors eyes. Blocking one or both the sensors will break the beam. Once that happens, it affects the sensors ability to work properly, leading to the blinking issue.

    The garage door sensors mounted on the tracks on both sides of the door are designed to work by each sensor sending out a signal across the doorway.

    The first thing you may want to do is check for any physical objects sitting directly in front of either sensor. Removing such an object should restore normal functioning unless there is another malfunction.

    If there are no obvious obstructions, a dirty lens might be the culprit. Thankfully, this problem is one of the easiest to fix.

    Use a clean, lint-free cloth to wipe the sensors to remove any accumulated dirt blocking them. It is important to be careful while cleaning the sensors because the eyes have a glass that could break if handled with little care.

    The Importance Of Garage Door Sensors

    Garage door sensors are more than just a convenient element of your door, theyre a critical safety feature for your home. Between 1982 and 1992, garage door accidents caused about eight deaths per year among children under the age of 15. In 1990, President George H. W. Bush signed Public Law 101-608, the Consumer Product Safety Improvement Act of 1990. This federal legislation mandates that all garage door openers produced after 1993 meet the requirements set forth in UL325.

    It takes only a moment for a child or pet to scurry beneath a garage door. A single garage door typically weighs at least 130 pounds, and a double door with windows will weigh closer to 350 pounds. Its crucial that you keep proper protections in place to prevent your garage door from closing accidentally when an obstruction is in the way.
