Your springs do the heavy lifting
The spring system counterbalances the weight of the door. The opener moves a properly balanced door; it is not meant to carry its full weight. If a spring breaks, continuing to run the opener can put additional stress on the system.
The correct spring depends on the door
Spring selection depends on the door’s weight, dimensions, and spring configuration. A replacement should be matched to the actual door, followed by balance and operation checks. Spring hardware is under tension and requires professional handling.
Until your appointment
Stop using the opener if you suspect a broken spring. Keep people and pets clear of the door. Do not loosen spring hardware or try to lift a door that may fall or close unexpectedly.
Keep people and pets clear. Do not adjust springs, cables or bottom brackets. Stop operating a crooked, damaged or unusually heavy door until it has been assessed.
