TROUBLESHOOTING

1. The opener doesn't operate from either the

START/STOP button or the transmitter:

• Does the opener have electric power? Plug a lamp into the out-

let. If it doesn't light, check the fuse box.

• Have you disabled all door locks? Review installation instruc-

tion warnings on page 2.

• Is there a build-up of ice or snow under the door? The door may

be frozen to the ground. Remove any restriction.

• The garage door spring may be broken. Have it replaced.

2. Opener operates from the transmitter, but not

from the wired wall control (optional accessory):

• Is the wall control lit? If not, reverse the two wires. If the open-

er runs, check for a faulty wire connection at the wall control, a

short under the staples, or a broken wire.

• Are the wiring connections correct? Refer to wired wall control

instructions.

3. The door operates from the START/STOP button or

wired wall control, but not from the wireless wall

control or transmitter:

• If the wired wall control is installed and it is flashing, ensure the

lock feature is off.

• Program the opener to match the transmitter code. (Refer to

section 24). Repeat with all transmitters.

4. The transmitter has short range:

• Change the location of the transmitter in your car.

• Check to be sure the antenna on the bottom of the opener

extends fully downward.

• Some installations may have shorter range due to a metal door,

foil backed insulation, or metal garage siding.

• Replace transmitter batteries.

5. The garage door opens and closes by itself:

• Be sure that all transmitter push buttons are off.

• If the wired wall control (optional accessory) is installed, remove

the bell wire from the wired wall control terminals and operate

from the START/STOP button or transmitter. If this solves the

problem, the wired wall control is faulty (replace), or there is an

intermittent short on the wire between the wired wall control

and the opener.

• Clear memory and re-program all wireless wall controls and

transmitters.

6. The door will stop, reverses slightly away from the

obstruction then stop:

• Is something obstructing the door? Is it out of balance, or are

the springs broken? Remove the obstruction or repair the door.

7. The door reverses for no apparent reason and

opener light flashes for 5 seconds after reversing:

• Check The Protector System

(IR Beams), if installed Correct

alignment if the red light on the beam is solid.

8. The door opens but won't close or reverses while

closing:

• Is something obstructing the door? Pull the manual

release handle. Operate the door manually. If it is unbal-

anced or binding, call a trained door systems technician.

• Clear any ice or snow from the garage floor area where

the door closes.

• Repeat the limit and force setting in section 18 and section 19.

Repeat safety reverse test after adjustments.

9. The opener strains to operate door:

• The door may be out of balance or the springs may be

broken. Close the door and use the manual release to dis-

connect the door. Open and close the door manually. A

properly balanced door will stay in any point of travel

while being supported entirely by its springs. If it does not,

disconnect the opener and call a trained door systems

technician.

10. The opener hums briefly, then won't work:

• Check that the door is not in manual release mode, refer

section 14.

• The garage door springs may be broken. See above.

• If the problem occurs on the first operation of the opener,

door may be locked. Disable any door locks.

11. The opener won't operate due to power failure:

• Use the manual release handle to disconnect the door. The door

can be opened and closed manually. When power is restored, re-

engage the opener, refer section 14.

12. The opener flashes once every minute for 10

minutes after operating (optional feature):

• Door and opener requires service. Contact your local

Chamberlain Merlin dealer.
