I just purchased my first home and it has a Craftsman Part Number: 41A4315-7D. It's a 1/2 hp opener that works with the button on the wall. There was a remote that the previous owner left in the house that doesn't do anything. I've held the program button on the opener for 10 sec to clear any codes stored and attempted to reprogram.
I replaced the battery in the remote still no response. The remote looked pretty old so I bought a new Liftmaster 371LM remote and tried to program with the instructions on the opener. Still no response.
I felt like I read that the liftmaster remote would work with this opener. The receiver on the opener could be bad but I'm not sure how to test that. Are there aftermarket receivers that can turn a non-remote opener into a remote controlled one? Am I better off just getting a whole new opener?
Thanks for any input.
