Chamberlain ML5500 manual HAVING A PROBLEM? Continued, SPECIAL FEATURE OF THE MOTORLIFT 5500, 6-GB

HAVING A PROBLEM? (Continued)

7. 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, Vibration Isolator Kit 41A3263 can be installed. This kit was designed to eliminate the "sounding board effect" and is easy to install.

8. The garage door opens and closes by itself:

•Is there a neighbor with a garage door opener using the same frequency code? Change your code.

•Make sure remote push button is not stuck “on.”

9. Door stops but doesn't close completely:

Review Travel Limits Adjustment.

Repeat safety reverse test after any adjustment of door arm length, close force or down limit.

10. 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.

11. Opener light does not turn on:

Replace light bulb (40 Watts maximum, 230V, E27). Replace burned out bulbs with rough service light bulbs.

12. Opener light does not turn off:

There may be a defective earth at the ceiling or wall receptacle. The unit must be earthed.

13. 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.

14. 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.

15. Opener won't activate due to power failure:

•Pull manual release rope and handle straight down to disconnect trolley. Door can be opened and closed manually. When the power is restored, pull the manual release handle toward the opener at a 45˚ angle, so that the trolley release arm is horizontal. The next time the opener is activated, the trolley will reconnect.

•The Outside Quick Release accessory 1702EML (if fitted) disconnects the trolley from outside the garage in case of power failure.
