If you can identify the model number, it may be possible to locate a manual from 1997 using the internet with http://www.google.com

According to one of the web sites above, "Stanley stopped making garage door openers and gate operators in 1997. Spare parts can be difficult to find however original and compatible remote controls are still widely available, most of the remote controls used by Stanley were manufactured by the Linear corporation.
Stanley made garage door openers for other companies and many parts are interchangeable some of the brands they manufactured for are Vemco, U-Install, Quiet Glide, Light Maker, Home Innovative, Whistler, Popular Mechanics, and Secure Code."

If you have safety electric eyes, make sure they are not blocked and aligned, (you should get a light on the eye(s)).

Not great info, but there are links to email the remnants of the Stanley Garage Door company (the companies using the Stanley name went bankrupt), as well as some links for parts.
There is also this link for Stanley Garage Door manuals from the page above: http://www.aaaremotes.com/stowma.html

Mine is doing the same thing. Did you get your problem resolved and if so what did you do? Thanks

If the motor runs and the chain does not then you have stripped the gears and will need to replace them. If the motor runs, the chain moves but the door does not move then the trolley is not attached or needs to be replaced. Thanks BB

the door beams are not working properly. Let me know what you find
