Hmmmm, maybe my opener was built in the same lot as yours, Frank. Starting last summer, I'd never know when the door would close all the way or how many times it would take to get it to close. We could go for days without a problem, and then all of a sudden it would stop halfway down and go back up. It might take 6 or 8 tries to get it to close completely.
I did all of the things that have been mentioned. I opened things up and cleaned contacts and checked connections, I re-programmed our remotes, I changed all of the batteries, and I even had the garage door service man come out. That wasted $25.00! /forums/images/graemlins/mad.gif
It seemed that we had more of a problem with this when the weather was over 50 degrees. The door worked fine all winter, but it's started doing it again now. So the other night, when we were out picking up new doorknobs and hardware at Home Depot, I told the wife we're buying a new opener and installing it this week. That's all I'd need once I had the house on the market come May 1st, a potential buyer is going through the house and can't get the garage door to go up or down. /forums/images/graemlins/crazy.gif
Besides, it's one more thing that I can say is NEW to a potential buyer! /forums/images/graemlins/wink.gif
