Having a Problem?
(Continued)
Situation
Probable Cause & Solution
DOOR REVERSES FOR NO
APPARENT REASON
1. Is something obstructing the door? Pull red manual release handle. Operate
door manually. If it is unbalanced or binding, call for professional garage
door service.
2. Clear any ice or snow from garage floor area where garage door closes.
3. Review the Force Adjustment Chart on page 21.
REPEAT SAFETY REVERSE TEST after adjustment is complete.
4. If door reverses in FULLY CLOSED position, decrease travel limits (Page 20).
REPEAT SAFETY REVERSE TEST after the adjustment is complete. THE
NEED FOR OCCASIONAL ADJUSTMENT OF THE FORCE AND LIMIT
SETTINGS IS NORMAL. WEATHER CONDITIONS IN PARTICULAR CAN
AFFECT DOOR TRAVEL.
5. Check the Protector System™ (if you have installed this accessory). If the light
is blinking, correct alignment.
OPENER LIGHT
DOES NOT TURN ON
1. Replace the light bulb (75 watts maximum). Use a "garage door opener
bulb" if standard bulb burns out prematurely due to vibration. Vibration may
be caused by loose end panel. Retighten screws.
DOES NOT TURN OFF
1. There may be a defective ground at ceiling or wall receptacle.
UNIT MUST BE GROUNDED.
2. Is the Light Feature ON? (Model 5000E) Turn it OFF.
OPENER STRAINS OR
MAXIMUM FORCE IS
NEEDED TO OPERATE DOOR
1. Door may be out of balance 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.
OPENER MOTOR HUMS
BRIEFLY, THEN WON'T WORK
1. Garage door springs are broken. SEE ABOVE.
2. The trolley may be jammed into stop bolts. Pull or push on door while motor
is humming to release jammed condition. Re-adjust door limits (page 20) to
prevent over-travel.
REPEAT SAFETY REVERSE TEST after adjustment is complete.
3. If the problem occurs on first operation of the opener, door is locked.
DISABLE DOOR LOCK. If chain was removed and reinstalled, motor may
be out of phase. Remove chain; cycle motor to the down position. Observe
drive sprocket. When it turns in clockwise direction and stops in down
position, reinstall chain.
REPEAT SAFETY REVERSE TEST after adjustment is complete.
OPENER WON'T OPERATE
DUE TO POWER FAILURE
1. Use manual release rope and handle to disconnect trolley. Door can be
opened and closed manually. When the power is restored, press the door
control button and trolley will automatically reconnect.
2. The Emergency Release Keylock accessory (for use on garages with no
service door) disconnects the trolley from outside the garage in case of
power failure.
CHAIN DROOPS OR SAGS
1. It is normal for chain to droop slightly in the closed door position. Use
manual release rope and handle to disconnect trolley. If chain returns to
normal height when the trolley is disengaged and door reverses on a 25mm
obstruction, no adjustments are needed.
OPENER NOISE IS
DISTURBING IN LIVING
QUARTERS OF HOME
1. 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.
