  1. Check that you have power to the garage door opener.
  2. Check the sensor wire is not shorted or broken.
  3. Check that the sensors are wired correctly; white wires to white terminal and white/black wires to grey terminal.

If the green receiving sensor LED is blinking, the sensors are obstructed or misaligned:

  1. Check for obstructions in the sensor light beam.
  2. Align the sensors.
  3. If the receiving sensor (green LED) faces direct sunlight, switch the sensors to opposite sides of the door to assure proper operation.

Adjustments

Introduction


Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

  • Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system.
  • After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.


To prevent damage to vehicles, be sure fully open door provides adequate clearance.

Your garage door opener is designed with electronic controls to make setup and adjustments easy. The adjustments allow you to program where the door will stop in the open (UP) and close (DOWN) position. The electronic controls sense the amount of force required to open and close the door.

NOTE: If anything interferes with the door's upward travel it will stop. If anything interferes with the door's downward travel, it will reverse.

Routine Maintenance Can Prevent Tragedies

Make monthly inspection and testing of your garage door and opener system a part of your regular routine. Review your owner's manual for both the door and door opener. If you don't have the owner's manuals, contact the manufacturer(s) and request a copy for your specific model(s). Look for the opener model number on the back of the power unit.


Springs are under high tension. Only qualified individuals should adjust them.

Visually check the door and installation:

  • Starting with the door in the closed position, use the manual disconnect on the opener to disconnect the door.
  • Look for signs of wear or damage on hinges, rollers, springs, and door panels.
  • These parts may require periodic lubrication. Check the owner's manual for suggested maintenance.
  • If any signs of damage are evident, contact a trained door systems technician for assistance.
  • Verify the photoeye height is no higher than 6" from the garage floor.

Visually check the door and installation

Test the door for proper operation:

  • Open and close the door manually using handles or suitable gripping points.
  • The door should move freely and without difficulty.
  • The door should balance and stay partially open 3–4 feet above the floor.
  • If you detect any signs of improper operation, contact a trained door systems technician for assistance.

Test the door for proper operation

Test the opener safety features:

  • Reconnect the opener to the door using the manual disconnect and open the door.
  • Place a 2x4 board flat in the path of the door (1) and try to close it (2). The door should stop when it comes in contact with the 2x4 and then reverse direction.
  • Block the photoelectric sensor by waving an object in front of the sensor and attempt to close the door. The door should not close unless the wall-mounted push button is manually held during operation.
  • If the opener does not perform as described, contact a trained door systems technician for assistance.
