To Erase All Codes From
Motor Unit Memory
To deactivate any unwanted remote, first erase all codes:
Press and hold the "learn" button on motor unit until the learn indicator
LED goes out (approximately 6-9 seconds). All previous codes are now
erased. Reprogram each remote or keyless entry you wish to use.
The Remote Control Battery
To prevent possible SERIOUS INJURY or DEATH:
• NEVER allow small children near batteries.
• If battery is swallowed, immediately notify doctor.
TROUBLESHOOTING
1. The operator doesn't operate from either the Door Control or the
remote control:
Does the operator 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.
Is there a build-up of ice or snow under the door? The door may be
frozen to the ground. Remove any restriction.
The door spring may be broken. Have it replaced.
2. Opener operates from the remote, but not from the Wireless Wall
Control:
• Check the LED on the Wall Control to ensure the LED turns on when
button is pushed. If the LED is weak or not on Change the batteries.
(Remove cover and replace with correct batteries)
• If the LED turns on and is strong check to ensure the unit is
programmed into the unit.
3. The door operates from the Door Control, but not from the remote
control:
• Is the door push bar flashing? If so, Lock mode is engaged. Make
sure it is off by pressing the
Lock button for two seconds.
• Program the operator to match the remote control code. (Refer to
instructions on the motor unit panel.) Repeat with all Remote.
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 siding.
5. The door opens and closes by itself:
Be sure that all remote control push buttons are off.
Remove the bell wire from the door control terminals and operate
from the remote only. If this solves the problem, the door control is
faulty (replace), or there is an intermittent short on the wire between
the control console and the motor unit.
Clear memory and re-program all remote controls.
6.
The door doesn't open completely:
Check power door lock.
Is something obstructing the door? Is it out of balance, or are the
springs broken? Remove the obstruction or repair the door.
7.
The door opens but won't close:
Check cable tension monitor (see installation step 4).
If the operator clicks, check the safety reversing sensor. See
Installation Step 9.
If the operator does not click and it is a new installation. See
Adjustment Step 2. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
8.
The door reverses for no apparent reason and operator LED
doesn't blink:
Check cable tension monitor (see installation step 4).
Is something obstructing the door? Pull the emergency release
handle. Operate the door manually. If it is unbalanced or binding,
call a trained door systems technician.
Clear any ice or snow from the floor area where the door closes.
Review Adjustment Step 2.
Repeat safety reverse test after adjustments.
9.
The door reverses for no apparent reason and operator LED
blinks for 5 seconds after reversing:
Check the safety reversing sensor. Remove any obstruction or align
the receiving eye.
10. The operator strains to operate door:
The door may be out of balance or the springs may be broken.
Close the door and use the emergency release handle to
disconnect the door. 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 operator and call
a trained door systems technician.
11.The operator motor hums briefly, then won't work:
The door springs may be broken. See above.
If the problem occurs on the first operation of the operator, door may
be locked. Disable the power door lock.
12.The operator won't operate due to power failure:
Manually open the power door lock.
Use the emergency release handle to disconnect the door. The door
can be opened and closed manually. When power is restored, pull
manual release a second time.
If an EverCharge Unit is connected, the operator should be able to
operate up to 20 times without power.
13. Door loses limits.
Collar not tightened securely. Tighten collar
(see Assembly Steps 1 and 2) and reprogram limits
(see Adjustment Step 1).
14. The operator moves when the door is in operation:
Some minor movement is normal for this product. If it is excessive
the collar will wear prematurely.
Check to make sure the torsion bar is not moving left/right
excessively.
Check to make sure the torsion bar is not visibly moving up and
down as it rotates.
Check that the operator is mounted at a right angle to the jackshaft.
If not, move the position of the mounting bracket.
15. Power lock makes noise when operating.
Call Chamberlain-Liftmaster dealer for replacement power lock.
