Installed two new springs on automatic doorman model 455 and it won't close or open. chain will not move door where are adjustment screws? I think that may be the problem


Does it make a noise? Did it run before you changed the springs? Did you replace springs on opener or on the door? What adjustment screws are you looking for? Do you think they went out of adjustment when you changed the springs?

You are probably right about the motor going.Does it get to a point where the door stops and the motor is making a humming sound?

Does anyone know where I can get the 9 tooth chain sprocket (not the one on the unit) for a Doorman 455?


If you are looking for the sprocket that goes on the door end of the T-rail you can call any Chamberlain or Liftmaster dealer in the yellow pages. They might even sell you a used one off an old opener they have changed out.

I have an Automatice Doorman model 455 garage door opener. I recently changed the battery for its remote control. How do I reprogram the remote control?


Your opener is very old and not only are there no parts available but it is not a programmable system. Your best bet is to buy something more up to date which will be much safer to operate.
