    How to Adjust Garage Door Opener

    Over the years, garage doors have evolved to serve more convenience and benefits to homeowners.

    Garage doors can now be controlled remotely and are equipped with safety sensors that prevent accidents that could harm family members.

    Nevertheless, garage door systems contain a large, heavy moving object, making them prone to falling out of adjustment; hence, they need to be maintained to remain functional at all times.

    Accordingly, one of the most common parts that get adjusted often is the garage door opener, and for two main reasons: to adjust travel and force limits.

    Things You Will Need

    If you feel you need to adjust your garage door opener, ensure to be equipped with the following:

    • Flathead Screwdriver
    • Stepladder
    • Flashlight

    Travel Limits

    Garage door travel limits refer to the points in which the door stops moving when it is opened or closed.

    If you notice that your door isn’t closing or opening completely, or if you notice that your door reverses after closing completely, you might need to adjust your opener’s travel limits.

    To be more certain, run your garage door opener through a full opening and closing cycle and observe closely.

    To begin adjustment, head on to your garage door’s opener with the aforementioned tools and equipment and look for the two limit screws.

    Note that the screws are different for the upward and downward travel limit.

    Adjusting the Upward Travel Limit

    One turn of the UP limit screw CLOCKWISE ADDS 2 inches of upward door travel, and one turn COUNTERCLOCKWISE SUBTRACTS 2 inches of upward door travel.

    If your garage door hangs too low when opened, turn the upward limit clockwise; similarly, if the door opens too much, turn the upward limit counterclockwise.

    Ensure that the space provided when you open your garage door has enough allowance for your vehicle to pass under.

    Adjusting the Downward Travel Limit

    In reverse, one turn of the DOWN limit screw CLOCKWISE SUBTRACTS 2 inches of downward door travel, and one turn COUNTERCLOCKWISE ADDS 2 inches of downward door travel.

    If your garage door doesn’t fully close, turn the downward limit counterclockwise; similarly, if your garage door reverses on its own after fully closing, turn the downward limit clockwise.

    Ensure that your garage door closes without activating the safety reverse sensors.

    Tip

    After every adjustment, run the opener through a full opening and closing cycle and watch closely for any inadequacies.

    Also, make sure to test the safety reversal system to ensure that it is not compromised despite the adjustments made.

    To test the safety sensor, open your garage door, stand from a safe distance, and close the garage door with your hand directly under the closing door.

    If the door reverses after coming in contact with your hand, your safety reversal feature is functional.

    Otherwise, if the door continues to close, quickly retract your hand; your safety reversal is malfunctioning and your force limits will need some adjustment

    Force Limits

    On the last of how to adjust garage door opener, garage door force limits refer to the force that a garage door goes upward or downward.

    The force limit can also affect the sensitivity of the safety reversal feature; meaning, if the force limit is too high, more force is needed to activate the reversal feature.

    On the other hand, if the force limit is too low, the garage door reversal could get activated even with only the friction of the door traveling downwards.

    Hence, it is essential to keep the force limit to a manageable level.

    Adjusting the Upward Force Limit

    If your garage door doesn’t stop when you grasp the bottom halfway through opening, then your upward force limit is too high.

    Similarly, if your garage door isn’t open at least 5 feet high, then your upward force limit is too low.

    To DECREASE the UPWARD force limit, turn the force adjustment knob COUNTERCLOCKWISE; to INCREASE the UPWARD force limit, turn the knob CLOCKWISE.

    Ensure that you only make small adjustments until you find the force that you’re satisfied with.

    Adjusting the Downward Force Limit

    If your garage door doesn’t reverse when you block the downward travel with your hand, then your downward force limit is too high.

    Similarly, if your garage door reverses without anything blocking the door during its downward travel, then your downward force limit is too low.

    To DECREASE the DOWNWARD force limit, turn the force adjustment knob COUNTERCLOCKWISE; to INCREASE the DOWNWARD force limit, turn the knob CLOCKWISE.

    Tip

    Similar to travel limit adjustments, ensure to test the safety reversal feature after making any adjustment to the force limits.

    Make sure that not a huge amount of force is required to activate the reversal feature.
