Sears/Craftsman garage door opener
I just bought an older house and there is a Sears/Craftsman garage door opener in the garage. There is no remote and no control panel anywhere in the garage. All I can tell is the unit receives power cuz the light bulb will go on.
It is a 1/3 hp unit, model 139.18570SR and the digital receiver is 41A3516-2. Any ideas how I can find out if it works?? or where I can get a remote? I tried taking off the cover to see if there was a code set inside, but could not find anything. Last house/garage had a stanley opener and I know I could see the code settings in it.
Any help would be appreciated.
