Chamberlain 459950, 547445, HD900CD Set the Force

ADJUSTMENT STEP 2

Set the Force

The force setting measures the amount of force required to open and close the door.

1.Push the purple button twice to enter into the Force Adjustment Mode. The LED will ﬂash quickly.

2.Push the door control or programmed remote control. The door will close (DOWN).

3.Push the door control or programmed remote control again. The door will open (UP).

4.Push the door control or programmed remote control a third time to close the door (DOWN).

The LED will stop ﬂashing when the force has been programmed.

The door must travel through a complete cycle, up and down, in order for the force to be set properly. If the garage door opener cannot open and close the door fully, inspect the door to ensure that it is balanced properly and is not sticking or binding.

If the door is not stopping exactly where you would like it, repeat Program the Travel Limits.

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

•Too much force on garage door will interfere with proper operation of safety reversal system.

•NEVER use adjustments to compensate for a binding or sticking garage door.

•After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" (3.8 cm) high object(or 2x4 laid ﬂat) on ﬂoor.
