Just purchased and installed a new Sears 3/4hp garage door opener with a
screw drive mechanism. I am looking for durability, speed (on the box it
claims faster speed over 1/2hp), and quiet operation.
Installation was straightforward and simple, but the long screw inside the
channel "chatters" during operation. Still chatters after disconnecting the
door and running the opener itself. The door itself opens/closes
quietly...the noise is from the GDO. Sears claims this model never need
Also it does not have any apparent speed advantage over my neighbors' 1/2hp
openers. But mine is noisier!
Otherwise it works, but I am not happy with this expensive purchase. Any
suggestions other than taking it all down and returning this to Sears?
