Hi. Thanks for those who responded to my original request for info. I ordered parts to repair my Stanley garage door opener from a company out of Orestes, IN (1st Garage Door Openers,Inc. @www.stanley-garage-door-opener.com). They are a great online resource for parts for garage doors. BUT, BUT, BUT....anyone who orders from them should know that the installment direction sheets may not be enough to replace your part.
Because the old part to my opener was so broken, I couldn't figure how to install the new part. The directions sent with the new part were limited and not accurate for proper installation. Of course, I did contact this company but they do not offer any technical assistance; they are simply a supplier of parts. Through trial and error, I had success getting my door working again.
I thought this was worth sharing. Thanks again.
