master mechanic 1/2hp opener


(jeff)

I have a master mechanic 1/2hp opener,the remote failed so I bought a chamberlain universal remote. It does work, but, now my neighbors remote will open and close my door. How do I wipe my opener and reprogram the stupid thing?


Liftmaster has changed how they deliver information online. Manuals are no longer available; instead we get videos to help us which is probably better than my trying to explain, especially since I have not been able to work in 17 years.
