PROBABLE CAUSE & SOLUTION

1.Is something obstructing the door? Pull red emergency release handle. Operate door manually. If it is unbalanced or binding, call a garage door serviceman to correct the problem.

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

3.Review the Force Adjustment Chart on page 17.

REPEAT SAFETY REVERSE TEST after adjustment is complete.

4.If door reverses in FULLY CLOSED position, decrease travel limits (see page 17).

REPEAT SAFETY REVERSE TEST after 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.The Infrared Reversing Sensor (If you have installed this accessory) may be misaligned or obstructed. Disconnect sensor and check door operation. If problem disappears, correct alignment.

DO NOT TURN ON

1.Replace light bulbs (75 watts maximum). Use e "garage door opener bulb" if standard bulb burns out prematurely due to vibration. Vibration may be caused by loose end panel. Retighten screws.

DO NOT TURN OFF

1.There may be a defective ground at ceiling or wall receptacle.

UNIT MUST BE GROUNDED.

2.Check the Light Feature on Wall Control. Is it ON? Turn it OFF.

3.If the light doesn'tturn off at the Wall Control, check yellow wire at Wall Control and opener screw terminal connections to be sure excess wire is not touching other terminals. If the connections are good, replace the yellow wire (it may be shorted or broken).

1.Door may be out of balance or springs are broken. Close door and use emergency 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 a garage door serviceman to correct problem.

1.Garage door springs are broken. SEE ABOVE.

2.The trolley may he jammed into stop bolts. Pull or push cn door while motor is

humming to release jammed condition. Re-edjust door limits (page 17) 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.

1.Use emergency release rope and handle to disconnect trolley. Door can be opened and closed manually. When the power is restored, press the Wall Control push button and trolley will automatically reconnect. Refer to Page 3 for'Lockout' Feature.

2.The emergency release Key Lock accessory (for use on garages with no service door) disconnects the trolley from outside the garage in case of power failure.

It is normal for chain to droop slightly in the closed door. position. Use emergency release rope and handle to disconnect trolley. If chain returns to normal height when the trolley is disengaged and door reverses on a"one-inch obstruction, no

adjustments are needed (see page 9).

1.If operational noise is a problem because of proximity of the opener to the living quarters, Vibration Isolator Kit 41A3263 can be ordered from any Sears Service Center and most Sears stores. This kit was designed to eliminate the 'sounding beard effect'and is easy to install.
