Tighten the Chain & Cable

• Spin the inner nut and lock washer down the
threaded shaft, away from the trolley.
• To tighten the chain, turn outer nut in the direction
shown. As you turn the nut, keep the chain
from twisting.
• When the chain is approximately 1/2" above the
base of the T-rail at its midpoint, re-tighten the
inner nut to secure the adjustment.
Sprocket noise can result if chain is either too
loose or too tight.
When installation is complete, you may notice some
chain droop with the door closed. This is normal. If
the chain returns to the position shown when the
door is open, do not re-adjust the chain.

available in your garage, use the maximum
height possible, or refer to page 14 for ceiling
installation.

WARNING

Install the Door Control

Do not connect to live electrical wiring. Connect
only to 24 Volt low voltage wires. Connection to
live wires or higher voltage may cause serious
injury from shock, burn or electrocution.
Children operating or playing with a garage
door opener can injure themselves or others.
The garage door could close and cause
serious injury or death.
Install the door control (or any additional push
buttons) out of the reach of children and away
from all moving parts of the door and door
hardware, but where the garage door is visible.
Do not allow children to operate the push
button(s) or the remote control(s).
A moving garage door could injure someone
under it. Activate the opener only when the
door is properly adjusted, you can see it
clearly, and there are no obstructions to door
travel.

Locate the door control within sight of the door
at a minimum height of 5 feet where small
children cannot reach, and away from all moving
parts of the door and door hardware.
The door control is typically attached directly to the
wall. If installing into drywall, drill 5/32" holes and use
the anchors provided. For pre-wired installations (as
in new home construction), Console models may be
mounted to a standard single gang box (Figure 2).
1. Strip 1/4" of insulation from one end of the bell
wire and connect it to the two screw terminals on
the back of the door control: white to 2, and
white/red to 1.
2. Pry off cover along one side with a screwdriver
blade (see Figure 1). Fasten with 6ABx1-1/4” selftapping screws (standard installation) or 6-32x1"
machine screws (pre-wired installation) as follows:
• Install bottom screw, allowing 1/8"

Electrical Requirements

To prevent electrocution or fire , installation
and wiring must be in compliance with local
electrical and building codes.
Do NOT use an extension cord, 2-wire adapter,
or change the plug in any way to make it fit
your outlet.

To reduce the risk of electric shock, your garage
door opener has a grounding type plug with a third
grounding pin. This plug will only fit into a grounding
type outlet.
If the plug doesn't fit into the outlet you have,
contact a qualified electrician to install the proper
outlet.

CAUTION
WARNING

To avoid installation difficulties,
do not run the opener at this time.

The Safety Reversing System
Information you'll need before you begin the installation of the safety reversing sensor.
The safety reversing sensor must be connected
and aligned correctly before the garage door
opener will move in the down direction. This is a
required safety device and cannot be disabled.

WARNING
Without a properly working safety reversing
sensor, persons (particularly children) could
be injured or killed by a closing garage door.
Read and follow all instructions.
To protect small children, install the safety
reversing sensor so that the beam will be no
higher than 4"-6" above the garage floor.
Disconnect power to the garage door opener
before installing the safety reversing sensor.

Installation procedures are the same for sectional
and one-piece doors.

CAUTION

The brackets must be securely fastened to a solid
surface such as the studs on either side of the door,
or add a piece of wood at each location if installing in
masonry construction.

Be sure power to the opener is disconnected.
The sending eye transmits an invisible light beam to
the receiving eye. The units can be installed on
either side of the garage door as long as the sun
never shines directly into the receiving eye lens.

the sensors as shown on page 21.
However, Figures 4 and 5 are variations which may
fit your installation requirements better. Make sure
the wraps and brackets are aligned so the
sensors will face each other across the garage
door.
• Fasten the "C" wraps to the mounting brackets
having square holes, using the hardware shown
in Figure 2.
• Connect each assembly to a slotted bracket, using
the hardware shown in Figure 3.
Note the alignment of the brackets for left and
right sides of the door.
• Finger tighten the lock nuts.
• Use bracket mounting holes as a template to
locate and drill (2) 3/16" diameter pilot holes on
both sides of the garage door, 4"-6" above the
floor but not exceeding 6". (See warning on
page 21.)
• Attach bracket assemblies with 1/4"x1-1/2" lag
screws as shown in Figure 3.
• Adjust right and left side bracket assemblies to the
same distance out from the mounting surface.
Make sure all door hardware obstructions are
cleared. Tighten the nuts securely.

CAUTION
To prevent damage to steel, aluminum,
fiberglass or glass panel doors, always
reinforce the inside of the door both vertically
and horizontally with an angle iron.

Follow instructions which apply to your door
type as illustrated below or on page 25.

A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should
cover the height of the top panel.
The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of
angle iron are used to create a "U"-shaped support. The best solution is to check with your garage door
manufacturer for an opener installation door reinforcement kit.

Adjust the UP and DOWN Limits
Do not make any limit adjustments until the
safety reversing sensors are completely
installed.

Improper adjustment of the travel limits will
interfere with the proper operation of the
safety reverse system. The door might not
reverse properly 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 30.

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
button. 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 30).

IMPORTANT SAFETY INSTRUCTIONS

WARNING
WARNING

To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Do not permit children either to operate or to
play with the opener. Keep remote control in a
location inaccessible to children.
3. Operate opener only when the door is in full
view and free from any obstruction. Keep the
door in sight until it is completely closed.
NO ONE SHOULD CROSS THE PATH OF THE
MOVING DOOR.
4. Check safety reversal system monthly. See
page 30. The garage door MUST reverse on
contact with a 2x4 board laid flat on the floor. If
an adjustment is made to either the force or
the limit of travel, both adjustments may be
needed and the safety reversal system must be
checked. Failure to properly adjust the opener
may result in severe injury or death.

5. If possible, use the emergency release only
when the door is in a closed position. Caution
should be taken whenever the disconnect cord
is actuated with the door open. Weak or broken
springs may cause the door to fall rapidly,
causing injury or death to persons.
6. KEEP GARAGE DOORS PROPERLY
BALANCED. See page 3. An improperly
balanced door may not reverse when required

Having a Problem?
Situation

Probable Cause and Solution

The opener doesn't
operate from either
the Door Control or
the remote control:

1. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light,
check the fuse box or the circuit breaker. (Some outlets are controlled by a door switch.)
2. Have you disabled all door locks? Review installation instruction warnings on Page 11.
3. Is there a build-up of ice or snow under the door? The door may be frozen to the
ground. Remove any restriction.
4. The garage door spring may be broken. Have it replaced.
5. Repeated operation may have tripped the overload protector in the motor. Wait
15 minutes. Try again.

Opener operates
from the remote
control, but not from
the Door Control:

1. Is the Door Control lit? If not, remove the bell wire from the opener terminal screws.
Short the red and white terminals by touching both terminals at the same time with a
piece of wire. If the opener runs, check for a faulty wire connection at the Door
Control, a short under the staples, or a broken wire.
2. Are the wiring connections correct? Review Step 6, page 18.

The door operates
from the Door
Control, but not from
the remote control:

1. Is any door push button flashing? If your model has the Lock feature, make sure the
lock is Off.
2. Your opener needs to re-learn a remote control code. Refer to Instructions on the
opener panel.
3. Program the receiver to match the remote control code.
4. Repeat the receiver programming procedure with all remote controls.

The remote control
has short range:

1. Change the location of the remote control in your car.
2. Check to be sure the antenna on the side or back panel of opener extends fully
downward.
3. Some installations may have shorter range due to a metal door, foil backed
insulation, or metal garage siding. (Antenna Extender Kit 41A3504)

Opener noise is
disturbing in living
quarters of home:

If operational noise is a problem because of proximity of the opener to the living
quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to
minimize vibration to the house and is easy to install.

The garage door
opens and closes
by itself:

1. Be sure that all remote control push buttons are not stuck in the “ON” position.
2. Remove the bell wire from the Door Control terminals and operate from the remote
control only. If this solves the problem, the Door Control is faulty (replace), or there is
an intermittent short on the wire between the Door Control and the opener.
3. Clear memory and re-program all remote controls.

The door doesn't
open completely:

1. Is something obstructing the door? Remove the obstruction or repair the door.
2. If the door has been working properly but now doesn't open all the way, increase the
up force. See page 29.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn
equals 2 inches of travel. See page 28.
Repeat the safety reverse test after the adjustment is complete.

The door stops but
doesn't close
completely:

Review the travel limits adjustment procedures on page 28.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.

Having a Problem? (continued)
Situation

Probable Cause & Solution

The door opens but
won't close:

1. If the opener lights blink, check the safety reversing sensor. See page 23.
2. If the opener lights do not blink and it is a new installation, check the down force.
See Adjustment Step 2, page 29. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.

The door reverses for
no apparent reason
and opener lights
don't blink:

1. Is something obstructing the door? Pull the red emergency release handle. Operate
the door manually. If it is unbalanced or binding, call for professional garage door
service.
2. Clear any ice or snow from the garage floor area where the door closes.
3. Review the force adjustment procedures on page 29.
4. If door reverses in the fully closed position, decrease the travel limits (page 28).
Repeat safety reverse test after adjustments to force or travel limits. The need
for occasional adjustment of the force and limit settings is normal. Weather
conditions in particular can affect door travel.

The door reverses for
no apparent reason
and opener lights
blink for 5 seconds
after reversing:

Check the safety reversing sensor. Remove any obstruction or align the receiving eye.
See page 23.

The opener light:

. . . doesn't turn on:
Replace the light bulbs (75 watts maximum). Use a standard neck garage door opener
bulb if regular bulb burns out.
. . . doesn't turn off:
Is the Light feature on? Turn it off.

The opener strains or
maximum force is
needed to operate
door:

The door may be out of balance or the springs are broken. Close the door and use the
emergency release to disconnect the trolley. Open and close the door manually. A properly
balanced door will stay in any point of travel while being supported entirely by its springs. If it
does not, disconnect the opener and call a professional garage door serviceman. Do not
increase the force to operate the opener.

The opener motor
hums briefly, then
won't work:

1. The garage door springs are broken. See above.
2. If the problem occurs on the first operation of the opener, door may be locked. Disable
the door lock. If the chain was removed and reinstalled, the motor may be out of phase.
Remove the chain; cycle the motor to the down position. Observe the drive sprocket.
When it turns in a clockwise direction and stops in the down position, reinstall the chain.
Repeat the safety reverse test after the adjustment is complete.

The opener won't
operate due to
power failure:

1. Use the emergency release to disconnect the trolley. The door can be opened and closed
manually. When the power is restored, press the Door Control push button and trolley will
automatically reconnect (unless trolley is in lockout position.) See page 32.
2. The Outside Trolley Release accessory (for use on garages with no service door)
disconnects the trolley from outside the garage in case of power failure.

The chain droops
or sags:

It is normal for the chain to droop slightly in the closed door position. Use the
emergency release to disconnect the trolley. If the chain returns to normal height when
the trolley is disengaged and the door reverses on a one-inch board, no adjustments
are needed (see page 11).
