I called for service and the technician called shortly thereafter to let me know he'd be at my home by the specified time. I showed Allan what the problem was and he gave me the "quick-fix" solution and the "best solution." The best solution was not as expensive as I thought plus he gave me $75 off with an online coupon. My garage door opens better than it did before and the problem will not reoccur for a very long time, if not ever. He was great.
