CARE OF YOUR OPENER

LIMIT AND FORCE ADJUSTMENTS:

Weather conditions may cause
some minor changes in door
operation requiring some 
re-adjustments, particularly
during the first year of
operation.

Pages 28 and 29 refer to the
limit and force adjustments.
Only a screwdriver is required.
Follow the instructions carefully.

Repeat the safety reverse test (Adjustment
Step 3, page 30) after any adjustment of limits 
or force.

Having a Problem?

1. The opener doesn't operate from either the

Door Control or the remote control:

• 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 wall switch.)

• Have you disabled all door locks? Review

installation instruction warnings on page 11.

• Is there a build-up of ice or snow under the door?

The door may be frozen to the ground. Remove
any restriction.

• The garage door spring may be broken. Have it

replaced.

• Repeated operation may have tripped the overload

protector in the motor. Wait 15 minutes and try
again.

2. Opener operates from the remote, but not from

the Door Control:

• Is the door control lit? If not, reverse the wires. If

the opener runs, check for a faulty wire connection
at the door control, a short under the staples, or a
broken wire.

• Are the wiring connections correct? Review

Installation Step 6, page 18. 

3. The door operates from the Door Control, but

not from the remote control:

• Is the door push bar flashing? If your model has

the Lock feature, make sure it is off.

• Program the opener to match the remote control

code. (Refer to instructions on the motor unit
panel.) Repeat with all remotes.

4. The remote control has short range:

• Change the location of the remote control in your

car. 

• Check to be sure the antenna on the side or back

panel of motor unit extends fully downward.

• Some installations may have shorter range due to

a metal door, foil backed insulation, or metal
garage siding (Antenna Extender Kit 41A3504).

5. 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 89LM can be installed. This kit
was designed to minimize vibration to the house
and is easy to install.

THE REMOTE CONTROL BATTERY

The lithium battery should produce
power for up to 5 years. To replace
battery, use the visor clip or
screwdriver blade to pry open the
case as shown. Insert battery
positive side up (+).

Dispose of old battery properly.
