Garage Door Opener
Please help with the insanity! All I need is a manual for my Craftsman GDO Model 139.53977SRT. Sears will be happy to sell me one for 5 bucks and ship it to me for another 20! I've got lights that don't come on at all, plus I'd like to do some other programming. Is there another source for the manual or all the information I'm looking for? Any help would be greatly appreciated.
