Where are the adjustments for a liftmaster garage door opener.

You can use both the up and down arrow buttons for adjustment. On most ceiling mounted liftmaster models you can find the limit adjustment screws on the left side panel of the opener. Upward and downward pointing arrows indicate the up and down. Locate the manual force adjustment dials at the back of the liftmaster garage door opener.

Locate the limit and force adjustment dials located on the back and sides of the unit. After any adjustments are made the safety reversal system must be tested. Press and release the up arrow button. Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system.

The exact position varies by model. When the garage door is in your desired down closed position press and release the rectangular adjustment button. Door must reverse on contact with 1 1 2 3 8 cm high object or 2 x 4 laid flat on floor. You might damage the motor of your garage door opener if there is a lot of resistance from the door tracks.
