When the garage automatic opener makes all the right sounds, but nothing happens!
This might put you in mind of kids who promise to tidy their room, but you find there is a clear disconnect between thought and action! With your automatic door opener, it's possible that the chain might be off the sprocket or the belt be broken. In both cases, it's best to arrange a service call.
However, it's possible the opener has become disconnected from the door - simply reconnect the trolley. It's also possible that a spring has broken. Check whether there is a gap of a couple of inches or so between one of them.
