Having A Problem - Merlin MT600 Installation And Operating Instructions Manual

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.
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 7.
3. Door operates from door control but not from remote:
• Replace battery if necessary.
• If you have two or more remotes and only one operates, review Program Your Opener, Remote and Keyless Entry steps 22 and
24.
• Is the door control button flashing? The opener is in lock mode. If you have a Motion Detecting Control Panel, push and hold
the Lock button for 2 seconds. The door control button will stop flashing.
4. Remote has short range:
• Is battery installed?
• 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.
5. Door reverses for no apparent reason and opener light doesn'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.
• Repeat Setting Limits and Force, see adjustment steps 26 and 27.
Repeat safety reverse test after adjustment is complete.
6. Door reverses for no apparent reason and opener 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. 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 89LM can be
installed. This kit was designed to reduce the "sounding board effect" and is easy to install.
8. The garage door opens and closes by itself:
Make sure remote push button is not stuck "on".
9. Door stops but doesn't close completely:
Repeat Setting the Limits, see adjustment step 26.
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 light does not blink and it is a new installation, repeat Setting the Limit and Force steps 26 and 27.
Repeat the safety reverse test after the adjustment is complete.
11. Opener light does not turn on:
Replace light bulb (230V/40W maximum). Replace burned out bulbs with rough service light bulbs.
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 to disconnect trolley. Door can be opened and closed manually. When the power is
restored, pull the manual release handle down and toward opener. 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.
