Chamberlain ML5500 Garage Door Opener User Manual


 
OPERATION OF YOUR OPENER
Your opener can be activated by any of the following devices:
• The Lighted Door Control Button. Hold the button down until door
starts to move.
• The Outside Keylock or Keyless Entry System (if you have installed
either of these accessories).
• The Remote Control Transmitter. Hold the push button down until the
door starts to move.
Opening the Door Manually:
Door should be fully closed if possible. Weak or broken springs could
allow an open door to fall rapidly. Property damage or serious
personal injury could result.
The door can be opened manually by pulling the release handle straight
down (so that the trolley release arm snaps into a vertical position). To
reconnect the door, pull the release handle toward the opener at a 45˚
angle so that the trolley release arm is horizontal. See illustration 14.
Do not use the manual release handle to pull the door open or closed.
When the Opener is Activated by Remote Control or Lighted Door
Control Button:
1. If open, the door will close. If closed, the door will open.
2. If closing, the door will reverse.
3. If opening, the door will stop (allowing space for entry and exit of pets
and for fresh air).
4. If the door has been stopped in a partially open position, it will close.
5. If an obstruction is encountered while closing, the door will reverse.
6. If an obstruction is encountered while opening, the door will stop.
7. The optional Protector System uses an invisible beam which, when
broken by an obstruction, causes a closing door to open and prevents
an open door from closing. It is STRONGLY RECOMMENDED for
homeowners with young children.
Allow a 15 minute cooling period after 5 continuous operations of the
opener.
The opener light will turn on: 1. when opener is initially plugged in;
2. when the power is interrupted; 3. when the opener is activated.
The light turns off automatically after 4-1/2 minutes. Bulb size is 40 Watts
maximum (230V, E27).
CARE OF YOUR OPENER
When properly installed, opener will provide high performance with a
minimum of maintenance. The opener does not require additional
lubrication.
Limit and Force Adjustments: These adjustments must be checked and
properly set when opener is installed. Only a screwdriver is
required. Weather conditions may cause some minor changes in the door
operation, requiring some re-adjustments, particularly during the first year
of operation.
Refer to the limit and force adjustments on page 4. Follow the instructions
carefully and repeat the safety reverse test after any adjustment.
Remote Control Transmitter: The portable remote control may be
secured to a car sun visor with the clip provided. Additional remotes can be
purchased at any time for use in all vehicles using garage. Refer to
Accessories. The receiver must be programmed to operate with any new
remote.
Remote Control Battery: The lithium batteries should produce power for
up to 5 years. When the light becomes dim or does not come on, replace
the battery. If transmission range lessens, check the battery test light.
To Change Battery: To replace batteries, use the visor clip or screwdriver
blade to pry open the case. Insert batteries positive side up. To replace
cover, snap shut along both sides. Do not dispose of the old battery with
household waste. Take battery to a proper disposal center.
MAINTENANCE OF YOUR OPENER
Once a Month:
Repeat safety reverse test. Make any necessary adjustments.
Manually operate door. If it is unbalanced or binding, call for professional
garage door service.
Check to be sure door opens and closes fully. Adjust Limits and/or Force
if necessary.
Once a Year:
Oil door rollers, bearings and hinges. The opener does not require
additional lubrication. Do not grease the door tracks.
HAVING A PROBLEM?
1. Opener doesn't operate from either door control or remote:
Does the opener have electric power? Plug lamp into outlet. If it doesn't
light, check the fuse box or the circuit breaker. (Some outlets are
controlled by a wall switch.)
Have you disengaged all door locks? Review installation instruction
warnings on page 1.
Is there a build-up of ice or snow under door? The door may be frozen to
ground. Remove any obstruction.
The garage door spring may be broken. Have it replaced.
Repeated operation may have tripped the overload protector in the motor.
Wait 15 minutes. Try again.
2. Opener operates from remote but not from door control:
Is door control button lit? If not, remove the bell wire from the opener
terminals. 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.
Are wiring connections correct? Review page 3.
3. Door operates from door control but not from remote:
Check the battery test light. Replace battery if necessary.
If you have two or more remotes and only one operates, review receiver
programming procedures on page 4.
Is the door control button flashing? The opener receiver must
re-learn the remote control code. Follow the instructions on page 4.
4. Remote has short range:
Is battery installed? Check battery test light. If the light is dim, change the
battery.
Change the location of the remote control on the car.
A metal garage door, foil-backed insulation or metal siding will reduce the
transmission range.
Make sure antenna is fully extended across ceiling towards the door.
5. Door reverses for no apparent reason and opener lights don't blink:
Is something obstructing the door? Pull manual release handle. Operate
door manually. If it is unbalanced or binding, call for professional garage
door service.
Clear any ice or snow from garage floor area where garage door closes.
Review Force Adjustment.
If door reverses in FULLY CLOSED position, decrease travel limits.
Repeat safety reverse test after adjustment is complete.
The need for occasional adjustment of the force and limit settings is
normal. Weather conditions in particular can affect door travel.
6. Door reverses for no apparent reason and opener lights blink for
5 seconds after reversing:
Check The Protector System(if you have installed this accessory). If the
light is blinking, correct alignment.
