I have a old Stanley model 1150 garage door opener. I only open it via a one off switch which I have connected to the two terminals on the back of the unit. Today it would sometimes would not open or close with the switch, but at times it would after I unplugged the power to the unit for a bit. Other than this, the old opener works fine. If it is the circut board (which I don't think is any longer available)can it be bypassed - so I can simply turn the motor on or off?

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."

replace the light bulbs or most people put cfl's in and the base of those bulbs are too big and the bulb actually doesnt contact the bottom of socket. try some old school bulbs. or just clean terminal bottom of socket. UNPLUG MACHINE FIRST OR YOU WILL TASTE PENNIES!!

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

You have shorted out your logic board. This could of been prevented with a surge protector 900 joules or higher. Whether you repair or replace get one. Stanley went out of business but you may still be able to find replacement parts online. Thanks BB

A Stanley garage door keypad is wall-mounted, battery-operated device that allows you to open your home's garage door electronically without having to manually lift the door or use a pull chain. The keypad uses a four-digit access code that you program after the keypad is initially installed. You can change the code, disable the keypad manually by entering a invalid code and reset the keypad if the device is not working properly. After you reset your Stanley garage door keypad, the device is ready to accept a new access code.

THE ADJUSTMENT IS SUPPOSED TO HAVE A 2ND NUT THE TWO TIGHTEN AGAINST EACH OTHER AND ACT LIKE A LOCK
