Routine Maintenance Can Prevent Tragedies

• 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.
• 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.
• 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.
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.
Test the opener safety features:
Test the door for proper operation:
Visually check the door
