Don't Chance It. Check It.™

You may not be able to see or hear it, but your Garage Door Opener may not be operating properly or even safely. Don't Chance It. Check It.™ using the LiftMaster 3-Step Safety Check:


Check the sides of the garage door for properly installed photo eyes (black sensors), mounted no higher than 6 inches off the floor.

Block the photo eye with an object over 6 inches tall, and press the Garage Door Opener's close button. The door should not close.

Lay an object that is at least 1.5 inches higher on the ground in the door's path, and press the close button. The door should reverse off this object.
