Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the
safety reversing sensors are completely
installed.

24

Limit adjustment settings regulate the points at
which the door will 

stop when moving up or down.

The door will 

stop in the up direction if anything

interferes with door travel. The door will 

reverse in

the 

down direction if anything interferes with the

door travel (including binding or unbalanced doors).

To operate the opener, press the Door Control push
bar. Run the opener through a complete travel
cycle.

• Does the door open and close completely?

• Does the door stay closed and not reverse

unintentionally when fully closed?

If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (See page 26).

Adjustment procedures are outlined below. Run
the opener through a complete travel cycle after
each adjustment. 

Repeated operation of the opener during
adjustment procedures may cause the motor to
overheat and shut off. Simply wait 15 minutes
and try again. 

Read the procedures carefully before continuing on
to Adjustment Step 2. Use a screwdriver to make
limit adjustments.

How and When to Adjust the Limits

If the door does not 

open completely

but opens 

at least five feet

Increase 

up travel. Turn the UP limit adjustment

screw clockwise. One turn equals 2" of travel.

If door does not open at least 5 feet:  Adjust the
UP (open) force as explained in Adjustment Step 2.

If the door does not 

close completely

Increase 

down travel. Turn the DOWN limit

adjustment screw counterclockwise. One turn 
equals 2" of travel.

If door still won't close completely, try lengthening
the door arm. (See page 22.)

If you have adjusted the door arm to the maximum
length and the door still will not close completely,
lower the header bracket. See Installation Step 1,
pages 8 and 9.

If the opener 

reverses in fully closed position

Decrease 

down travel. Turn the DOWN limit

adjustment screw clockwise. One turn equals 2" of
travel.

If the door 

reverses when closing and

there is no visible interference to travel cycle

If the opener lights are flashing, the Safety Reversing
Sensor is obstructed. Remove the obstruction.

Test the door for binding: Pull the manual release
handle. Manually open and close the door. If the door
is binding, call for garage door service. If the door is
not binding or unbalanced, adjust the DOWN (close)
force. See Adjustment Step 2.

Adjustment Section:  Pages 24 – 26

Improper adjustment of the travel limits will
interfere with the proper operation of the safety
reverse system. 

The door might not reverse

when required and could seriously injure or kill
someone under it. Test the safety reverse
system following all adjustments to the travel
limits. See page 26.
