How To Adjust Door Closing On Liftmaster Garage Door Opener
1: Understand the Components
Your Liftmaster garage door opener has several adjustable features, including:
- Limit Screws: These control how far the door opens and closes.
- Force Adjustment Dials: These regulate the amount of force the opener uses to move the door.
- Safety Sensors: Located near the base of the tracks, these prevent the door from closing if something is in the way.
2: Locate the Limit Screws
The limit screws are typically found on the side or back of the opener’s motor unit. They are often labeled “Up” and “Down” or have corresponding symbols to indicate opening and closing adjustments.
3: Adjust the Down Limit
- Start with a Test Run:
- Use the remote control to close the door and note where it stops.
- If it doesn’t close completely, you’ll need to increase the down limit.
- Make the Adjustment:
- Turn the down limit screw clockwise to increase the door’s closing distance.
- Turn it counterclockwise to decrease the distance if the door is closing too far.
- Test Again:
- Run the door after each adjustment to check its position.
- Repeat the process until the door closes securely without gaps or hitting the floor too hard.
4: Adjust the Force Settings
If the door doesn’t close smoothly, you may need to adjust the force settings.
- Locate the force adjustment dials, usually found near the limit screws.
- Turn the dial slightly clockwise to increase the force if the door struggles to close.
- Test the door after each adjustment to ensure smooth operation.
