Locate the Adjustment Controls
To adjust your LiftMaster Professional garage door opener, you first need to locate the adjustment controls. These controls are typically located on the back or side panel of the opener unit. The main controls you will be working with are:
- Travel limit adjustment screws

Travel Limit Adjustment
The travel limit adjustment screws control how far the garage door opens and closes. There are usually two screws, one for the up limit and one for the down limit. To adjust the travel limits, follow these steps:
- Locate the up limit adjustment screw. It is usually labeled or marked.
- Using a screwdriver, turn the up limit adjustment screw clockwise to decrease the travel distance, or counterclockwise to increase it.
- Test the door’s open and close positions after each adjustment until it reaches the desired position.

Force Adjustment
The force adjustment screws control the amount of force applied by the opener when closing the garage door. To adjust the force, follow these steps:
- Locate the force adjustment screws. They are usually labeled or marked.
- Using a screwdriver or wrench, turn the force adjustment screws clockwise to increase the force or counterclockwise to decrease it.
- Make small adjustments and test the door’s operation after each adjustment to ensure it closes smoothly without excessive force.
Check and Adjust the Safety Reverse System
The safety reverse system is an important safety feature in your LiftMaster Professional garage door opener. It ensures that the door reverses if it encounters an obstruction while closing. To check and adjust the safety reverse system, follow these steps:
- Place a piece of wood or a similar object on the ground in the path of the closing garage door.
- Activate the door to close using either the wall control or remote control.
- Observe the door’s behavior. If it fails to reverse upon hitting the obstruction, you need to adjust the force sensitivity.
- Locate the force sensitivity adjustment control on the opener unit. It is usually labeled or marked.
- Using a screwdriver or wrench, turn the force sensitivity adjustment control clockwise to increase sensitivity or counterclockwise to decrease it.
- Test the safety reverse system multiple times to ensure the door consistently reverses when an obstruction is present.
Perform Lubrication and Maintenance
In addition to adjusting the opener, regular lubrication and maintenance are crucial to keep your LiftMaster Professional garage door opener operating smoothly. Here are some tips for lubricating and maintaining your opener:
