LiftMaster garage door openers are safe, provided that homeowners take the proper precautions before installing them and when using them. Serious injury or death can occur if the opener is malfunctioning, so it is important to perform regular safety checks.
One way to ensure safety at all times is to perform maintenance safety checks with the garage door openers. First check that the photo eyes, or block sensors, on the sides of the garage door are mounted 6 inches off the floor or less. Next, block the photo eyes with an object that is at least 6 inches tall, and close the garage with the opener. If the door closes, the sensors need to be fixed.
Finally, place an object that is at least 7 1/2 inches high in the door's path, and close the garage again. If the door does not reverse off the object, call a trained door systems technician, as this problem can cause serious injury.
Safety risks are present with incorrect installation and handling. Prior to installation, it is important to disable all locks and remove all ropes connected to the garage door. Install the garage door opener on a properly balanced and lubricated garage door. It is important to do a safety check after installation to ensure everything was installed properly. If problems occur, avoid risk by calling a trained door-systems technician.
