    Garage Door Safety Sensors Explained

    Garage Door Safety Sensors – Safety measures are essential in any aspect of life.

    From protocols to products, the awareness of risks and hazards can greatly reduce their occurrence and keep users safe.

    A garage door safety sensor is one such device that is implemented in operating garage doors for safety measures.

    This device is a part of the garage door system which has been required by the U.S. Consumer Product Safety Commission (CPSC) since the year 1993.

    It has since prevented accidents that can cause injury, or even death, to people and animals alike.

    Garage door sensors were purely mechanical in the early years,

    wherein the garage door will automatically back up if it physically collides with an object.

    Nowadays, photoelectric sensors are more commonly used.

    These types of sensors are based on infrared lights, which can detect objects upon contact with the beams.

    A pair of sensors are placed about 6 inches above ground level at either side of the door.

    These are carefully aligned and faced with its other pair.

    If an object, say a person’s leg, moves past the sensor, the momentary blocking of the infrared beam will be read by the device and signal the garage door to automatically stop and move to the reverse direction.

    After this emergency halt, the door returns to its position of origin unless its emergency lever is pulled, then it is forced to close.

    Garage door sensors are universal, that is, all brands of sensors perform the same way.

    Models that are universal are compatible with garage door openers like LiftMaster, Chamberlain, Craftsman, and others.

    The level of safety these models offer are the same regardless of the garage door opener they are paired with.

    With the right maintenance, a sensor’s performance can last for a long time, and keep the garage owner’s mind at peace.

    Garage Door Troubleshooting

    Sensors can be damaged under poor maintenance or when hit by an object.

    External, unavoidable factors such as extreme sunlight, or moist, can affect your sensor’s performance.

    Physical impact on the sensors can cause internal defects to the device as well.

    The alignment of the sensors, the connection wires and/or the sensor devices themselves can be checked to isolate the problem of your setup.

    Some indications of malfunction are an inconsistent and unpredictable motion by the garage door.

    A defected sensor may cause it to open and close arbitrarily.

    The garage door’s late response to moving objects may also be observed.

    All these cause the system to serve its main purpose of safety for the user/s, which is why it must be addressed quickly.

    Here are some common garage door sensor problems and how they can be fixed

    • If the sensor’s detector is covered with dirt, wiping it with a soft, clean cloth can do the job.
    • A misalignment between the two sensors can be measured by a ruler or meter tape, and a bubble level. If the alignment is off, the bracket’s screw can be adjusted or tightened accordingly.
    • In case the sensor is not reading any movements at all, try checking the device’s power supply, and make sure there are no objects along the infrared beam.

    If the problem persists, or is not included in the situations written above, then you should ask for a technician to help solve the problem.

    Attempting to fix a suspected wiring problem can lead to a more damaged device than before it was handled.

    A specialist will be able to point out the problem for you and replace any parts necessary should this be the case.

    It can put you at ease knowing a dedicated technician can pinpoint the issue and address it with swift and proper action.

    Common garage door repair related FAQ

    How long does it take to replace a garage door?

    Roughly 3 to 4 hours, if done properly.

    How often should my a garage door be serviced?

    Your garage door is a large piece of moving equipment made up of many parts. Some families use their garage door more than their front door. We recommend having your garage door and operator serviced every year in order to ensure a properly working door and operator. The noises your door or operator makes are your initial “warning signs” that something is not quite right. The longer you put off the necessary service, the more damage may result.

    How long do garage door springs usually last?

    The most common torsion springs have an expected life of about 10,000 cycles (one opening and one closing is a cycle.)

    What is the life span of a garage door opener?

    The average life span of a door opener can vary from 10 to 20 years depending on the model and usage.
