How To Repair LiftMaster Garage Door Opener Model 1265 and 1265-267

MAINTENANCE SCHEDULE FOR LIFTMASTER GARAGE DOOR OPENER MODEL 1265 or 1265-267

Once a Month

  • Manually operate door. If it is unbalanced or binding, call a trained door systems technician.
  • Check to be sure door opens & closes fully. Adjust limits and/or force if necessary.
  • Repeat the safety reverse test. Make any necessary adjustments.

Twice a Year

  • Check chain tension. Disconnect trolley first. Adjust if necessary

Once a Year

  • Oil door rollers, bearings and hinges. The opener does not require additional lubrication. Do not grease the door tracks.

HOW TO REPLACE THE EMERGENCY RELEASE CORD

  • Remove the old emergency release cord
  • Thread one end of the new cord through the hole in the top of the red handle so “NOTICE” reads right sideup. Secure with an overhand knot at least 1″ from the end of the rope to prevent slipping.
  • Thread the other end of the rope through the hole in the release arm of the outer trolley.
  • Adjust rope length so the handle is 6 feet above the floor. Secure with an overhand knot.
  • NOTE: If it is necessary to cut the rope, heat seal the cut end with a match or lighter to prevent unraveling.

The Garage Shield

Have you thought about how easy it is for burglars to break into your garage by manipulating the garage door opener? The Garage Shield prevents burglars from using a coat hanger or wire to reach the emergency release cord. It’s an easy installation and takes only a few minutes. Once installed, the Garage Shield allows for unimpeded use of the emergency release cord and allows you to use your garage door as you normally do.

Be sure to check out THE GARAGE SHIELD. It provides an added layer of security as well as peace-of-mind against garage break-ins.

TROUBLESHOOTING THE SAFETY SENSORS

If the sending eye indicator light does not glow steadily after installation, check for:

  • Electric power to the opener.
  • A short in the white or white/black wires. These can occur at staples, or at screw terminal connections.
  • Incorrect wiring between sensors and opener.
  • A broken wire.

If the sending eye indicator light glows steadily but the receiving eye indicator light doesn’t:

  • Check alignment.
  • Check for an open wire to the receiving eye.

If the receiving eye indicator light is dim, realign either sensor.

 

HOW TO ADJUST THE UP AND DOWN TRAVEL LIMITS OF THE GARAGE DOOR

Limit adjustment settings regulate the points at which the door will stop when moving up or down.

To operate the opener, press the Door Control push bar. Run the opener through a complete travel cycle.

  • Does the door open and close completely?
  • Does the door stay closed and not reverse unintentionally when fully closed?

If your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails.

Adjustment procedures are outlined below. Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit adjustments. Run the opener through a complete travel cycle after each adjustment.

NOTE: Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Simply wait 15 minutes and try again.

NOTE: If anything interferes with the door’s upward travel, it will stop. If anything interferes with the door’s downward travel (including binding or unbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE UP AND DOWN TRAVEL LIMITS

If the door does not open completely but opens at least five feet:

  • Increase up travel.
  • Turn the UP limit adjustment screw clockwise. One turn equals 2″ of travel.
  • NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4″between the trolley and the bolt.

If door does not open at least 5 feet:

  • Adjust the UP (open) force as explained in Adjustment Step 2.

If the door does not close completely:

  • Increase down travel.
  • Turn the down limit adjustment screw counterclockwise. One turn equals 2″ of travel.
  • If door still won’t close completely and the trolley bumps into the pulley bracket, try lengthening the door arm and decreasing the down limit.

If the opener reverses in fully closed position:

  • Decrease down travel.
  • Turn the down limit adjustment screw clockwise. One turn equals 2″of travel.

If the door reverses when closing and there is no visible interference to travel cycle:

  • If the opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or obstructed.
  • Test the door for binding: Pull the emergency release handle. Manually open and close the door. If the door is binding or unbalanced, call for a trained door systems technician. If the door is balanced and not binding, adjust the DOWN(close) force.

HOW TO TEST AND ADJUST THE SAFETY REVERSAL SYSTEM

TEST

  • With the door fully open, place a one-inch board(or a 2×4 laid flat) on the floor, centered under the garage door.
  • Operate the door in the down direction. The door must reverse on striking the obstruction.

ADJUST

  • If the door stops on the obstruction, it is not traveling far enough in the down direction. Increase the DOWN limit by turning the DOWN limit adjustment screw counterclockwise 1/4 turn.
  • NOTE: On a sectional door, make sure limit adjustments do not force the door arm beyond a straight up and down position.
  • Repeat the test.
  • When the door reverses on the one-inch board, remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.

IMPORTANT SAFETY CHECK:

Repeat Adjustment Steps 1, 2 and 3 after:

  • Each adjustment of door arm length, limits, or force controls.
  • Any repair to or adjustment of the garage door(including springs and hardware).
  • Any repair to or buckling of the garage floor.
  •  Any repair to or adjustment of the opener.

TEST THE PROTECTOR SYSTEM

  • Press the remote control push button to open the door.
  • Place the opener carton in the path of the door.
  • Press the remote control push button to close the door. The door will not move more than an inch, and the opener lights will flash.

The garage door opener will not close from a remote if the indicator light in either sensor is off (alerting you to the fact that the sensor is misaligned or obstructed).

If the opener closes the door when the safety reversing sensor is obstructed (and the sensors are no more than 6″ above the floor), call for a trained door systems technician.
