Having a Problem?

(continued)

Situation Probable Cause & Solution

The door reverses for

no apparent reason

and opener lights

don't blink:

1. Is something obstructing the door? Pull the manual release handle. Operate the door

manually. If it is unbalanced or binding, call for professional garage door service.

2. Clear any ice or snow from the garage floor area where the door closes.

3. Review the force adjustment procedures on page 25.

4. If door reverses in the

fully closed

position, decrease the travel limits (page 24).

Repeat safety reverse test after adjustments to force or travel limits. The need

for occasional adjustment of the force and limit settings is normal. Weather

conditions in particular can affect door travel.

The door reverses for

no apparent reason

and opener lights

blink for 5 seconds

after reversing:

The opener lights:

. . . don't turn on:

Replace the light bulbs (75 watts maximum). Use a

standard neck

garage door opener

bulb if regular bulb burns out.

. . . don't turn off:

Is the Light feature

? Turn it

off.

The opener strains or

maximum force is

needed to operate

door:

The door may be out of balance or the springs are broken. Close the door and use the

manual release to disconnect the trolley. 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 professional garage door

serviceman.

Do not increase the force to operate the opener.

The opener motor

hums briefly, then

won't work:

1. The garage door springs are broken. See above.

2. If the problem occurs on the first operation of the opener, door may be locked.

Disable the door lock

. If the belt was removed and reinstalled, the motor may be out

of phase. Remove the belt; cycle the motor to the down position. Observe the drive

sprocket. When it turns in a clockwise direction and stops in the down position,

reinstall the belt.

Repeat the safety reverse test after the adjustment is complete.

The opener won't

operate due to

power failure:

1. Use the manual release to disconnect the trolley. The door can be opened and

closed manually. When the power is restored, press the Door Control push bar and

trolley will automatically reconnect (unless trolley is in lockout position.) See page 28.

2. The Outside Quick Release accessory (for use on garages with no service door)

disconnects the trolley from outside the garage in case of power failure.

The door opens but

won't close:

Check the safety reversing sensor. Remove any obstruction or align the receiving eye.

See page 19.

1. If the opener lights blink, check the safety reversing sensor. See page 19.

2. If the opener lights do not blink and it is a new installation, check the down force.

See Adjustment Step 2, page 25. For an existing installation, see below.

Repeat the safety reverse test after the adjustment is complete.
