Having A Problem - Chamberlain LiftMaster Professional 1000 Manuel D'instructions

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 professionally replaced.
• If not using the door within a door feature, check to be sure the jumper is
installed between the terminal leads.
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 Step 20.
3. Door operates from door control but not from remote:
• Try a new battery.
• If you have two or more remotes and only one operates, review receiver
programming procedures in Step 22.
4. Remote has short range:
• Is battery installed? Try a new one.
• 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.
• Use co-axial antenna adapter to move antenna. See Step 23.
• If the problem persists, the radio frequency module can be exchanged to
receive a different frequency.
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, reset the 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 door control button light
blinks for 5 seconds after reversing:
Check The Protector System™ (if you have installed this accessory). If the
light is blinking, correct alignment.
7. The garage door opens and closes by itself:
• (Keypad or code switch transmitters only) Is there a neighbor with a
garage door opener using the same code? Change your code.
• Make sure remote push button is not stuck in ON position.
8. Door reverses or doesn't close completely:
If it reverses or stops within 50mm of the floor, review "Force Adjustment"
and increase force. If necessary, repeat "Program the Travel Limits."
Repeat safety reverse test after any adjustment of door arm length,
close force or down limit.
9. Door opens but won't close:
• Check The Protector System™ (if you have installed this accessory). If
the light is blinking, correct alignment.
• If opener lights do not blink and it is a new installation, check the down
force.
Repeat the safety reverse test after the adjustment is complete.

10. Opener light does not turn on:
Replace light bulb (40 Watts maximum). Replace burned out bulbs with
rough service light bulbs (40W, 230V, E27).
11. Opener light does not turn off:
There may be a defective earth at the ceiling or wall receptacle. The unit
must be earthed.
12. Opener strains or maximum force is needed to activate door:
Door may be unbalanced or springs are broken. Close door and use
manual release rope and handle to disconnect trolley. Open and close
door manually. A properly balanced door will stay in any point of travel
while being supported entirely by its springs. If it does not, call for
professional garage door service to correct the problem. Do not increase
the force to operate the opener.
13. Opener motor hums briefly, then won't work:
• Garage door springs are broken. SEE ABOVE.
• If problem occurs on first operation of opener, door may be locked.
Disable door lock.
• Force setting may be too low. See Step 18.
• (C-rail chain drive only) The chain tension may be wrong. Disconnect the
door from the trolley and check that the compressed spring dimension is
20mm. See Step 7.
14. Opener won't activate due to power failure:
• C-rail: Pull manual release handle straight down to disconnect trolley. Door
can be opened and closed manually. Rotate lever to reconnect trolley.
T-rail: Pull manual release handle down and back (toward opener) to
disconnect trolley. When power is restored, pull handle straight down.
The next time the opener is activated, the trolley will reconnect.
• The Outside Quick Release accessory 1702E (if fitted) disconnects the
trolley from outside the garage in case of power failure.|
15. (Models 800 and 1000 only) Door will not close when in auto close
mode.
• Check for functioning Protector System.
• Be sure the timer is set between 60 and 180 seconds.
16. When in the limit learn mode, the opener will not automatically
stop and reverse when the door reaches the floor.
The opener uses a switch, internal to the motor, as a reference or "pass
point" to regulate limit adjustment. This point must occur ONLY ONCE in
the trolley's travel range, preferably about 75-90 cm from the fully closed
position. The opener is factory preset with the pass point in the correct
position for installation. However, if the opener was bench tested before
installing the rail, the pass point could be outside the desired position, or
could occur twice.
a. Determine the pass point. The wall pushbutton green indicator light will
blink momentarily when the pass point occurs.
b. If the pass point is incorrectly positioned or occurs more than once,
disconnect power immediately at the first blink.
c. Remove the chain from the sprocket and reposition the trolley to
75-90 cm from the closed position. Be certain the metal release lever is
in the latched position (see Illustration 5, bottom view).
d. Reinstall the chain and reprogram the limits. The push-button indicator
light should now blink ONCE at the correct position.
