DASMA, the Door & Access Systems Manufacturers Association, is an independent entity that has put in place many of the safety standards used in the garage door industry. DASMA recommends residential applications perform some basic routine maintenance on overhead sectional doors at least once a month. However, if a manufacturer recommends more maintenance or provides maintenance instructions always follow the manufacturer’s recommendations first.

DASMA suggests testing the safety features on your garage door at least once every 4 weeks to make sure they are working and in good order.

A reversal test is one way to make sure safety devices are functioning correctly. A reversal test is done by engaging the reversal feature of your operator which is responsible for preventing a door from crushing an obstruction if one is in the way. While a reversal feature may not prevent damage to property or injury since the door will contact the obstruction, but it will stop the motor from forcing the door downward on top of the obstruction. Garage door openers manufactured after January 1993 are required to have a reversal function. If your motor does not have a reversal function, the function does not work, or if you cannot locate it on your operator contact a local door professional immediately.

To check and see if your door reverses properly, DASMA suggests placing a 1 ½” thick piece of wood flat on the floor in the center of the door. Stand a safe distance away keeping fingers, arms and other objects away from the door and close the door using a transmitter or wall station. If the door closes onto the wood and does not reverse when it comes into contact with the plank contact a local overhead sectional door technician immediately.

Visual inspections are also encouraged on your overhead sectional door. If the springs, cables, pulleys, rollers, or other hardware look worn contact a professional for service. Never try to service your overhead sectional door on your own.
