Care Of Your Opener - Chamberlain ML700 Instructions

HAVING A PROBLEM? (CONT.)
12. Opener strains:
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.
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 is locked. Disable
door lock.
Repeat safety reverse test after adjustment is complete.
14. Opener won't activate due to power failure:
• Pull manual release rope and handle down and back to disconnect
trolley. Door can be opened and closed manually. When the power is
restored, pull the manual release handle straight down. The next time
the opener is activated, the trolley will reconnect.
• The Outside Quick Release accessory (if fitted) disconnects the
trolley from outside the garage in case of power failure.
15. Setting the limits manually:
1. Press and hold the black button until the yellow indicator light starts
flashing slowly then release.
2. Push and hold the black button until the door reaches the desired
UP (open) position. Adjust the position of the door by using the
black and orange buttons. Black moves the door UP (open) and
orange moves the door DOWN (close).
Check to be sure the door opens high enough for your vehicle.
3. Push the remote control or door control. This sets the UP (open)
limit and begins closing the door. Immediately press either the
orange or the black button. The door will stop.
Adjust the desired DOWN (close) limit position using the black and
orange buttons. Check to be sure the door is fully closed without
applying excessive pressure on the rail (rail should not bow
upwards and the chain/belt should not sag or droop below the rail).
Push the remote control or door control. This sets the DOWN
(close) limit and begins opening the door.
NOTE: If neither the black or the orange button is pressed before the
door reaches the floor, the operator will attempt an Automated Limit
Setting, reversing the door off the floor and stopping at the set Up
limit. If the worklight does not blink 10 times, limits setting has been
successful and doesn't need to be manually done; the DOWN limit will
be set to the floor. Regardless of setting the limits automatically or
manually, the force MUST be learned in order to properly
complete the setting of limits. Refer to section 26, Setting the
Force.
4. Open and close the door with the remote control or door control 2
or 3 times.
• If the door does not stop in the desired UP (open) position or
reverses before the door stops at the DOWN (close) position,
repeat Setting the limits manually one more time.
• If the door stops in both the desired UP (open) and DOWN (close)
positions, proceed to Test the Safety Reversal System.
