    Ways to Fix a Faulty Garage Door Sensor

    If you think your garage door sensors are malfunctioning, you can troubleshoot it by identifying the root cause.

    These are the few signs you can spot to determine a faulty sensor.

    This will help you identify if you can fix it yourself or need help from a garage door repair company near you.

    LED light indicators: Check the light blinks on your sensors when you try to close the overhead door. By checking it, you can tell if it’s out of alignment.

    If you see green lights, the sensors are working. On the other hand, red light means your sensors are not aligned.

    If you see red lights, check the bracket or try tightening a screw on the sensor.

    Once you execute one of the methods, you know you have fixed the problem if the light stops blinking and the door is operating normally again.

    Dirty sensor lenses: If you see your sensors are dirty, the dirt can block the sensors’ view. Hence, it won’t function normally.

    Wipe the lenses to remove the dirt and test your sensors if the door functions normally.

    Make sure to clean the sensors regularly to prevent garage door issues from happening.

    Damaged wires: Wires are responsible for the operation of your garage door sensors.

    However, it is also susceptible to wear and tear due to usage, weather factors, and pests.

    External factors such as rain, wind, and pest infestations can affect the wires.

    Inspect the wires if it’s damaged due to exposure to water or if there are signs of tampering.

    If so, you can follow these steps to check if the wires are faulty.

    However, make sure you have the skills and experience to perform the job on how to fix a broken garage door sensor wire.

    1. Remove the overhead door sensors from the brackets.
    2. Cut the wires 12 inches from the sensors or simply remove the nuts’ sensor wires.
    3. Detach the ends of wires from the sensors.
    4. Twist the colored wires together.
    5. Bring the sensors to your opener motor unit.
    6. Separate the wires from the grey and white terminals located at the back of the operator.
    7. Slide the white wires into the white terminal.
    8. Repeat step 7 for the white and black stripes and grey terminal.
    9. Face the sensors at each other. If both lights turn on, the wiring is most likely the issue. With this, replace the wires immediately.

    However, if the light does not turn on, then replace your sensors. You can watch out this video for the replacement of sensors.

    A sensor replacement is relatively easy to do. However, you need a highly-skilled technician to do it successfully.
