Mine had problems after I first moved in. I had the paperwork that the original owner of the house had left me, so I called the company that originally installed the opener. They came out and told me I needed a new one and tried to get me to buy one. They ended up not being on my home warranty, so the warranty place sent this guy out and he ended up being able to fix it. Dunno if he's still around or not...
