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

Adjustment Mode. The LED will ﬂ ash quickly.

2. Push the door control or programmed remote control.

third time to close the door (DOWN).

The LED will stop ﬂ ashing when the force has been

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
ﬂ at) on ﬂ oor.
