It was not the buzzer. The new timer seems to have fixed the problem. Both were easy to replace and this from a first time newbie. Following your video instructions made it simple. One thing I would strongly recommend is the taking of pictures with your phone prior to starting. That and all the color coded wiring was a big help. Time indicated below includes replacing both parts. If I can do, anyone can. Female, Age 74!
