Loud Buzzing from KitchenAid Door

Washer works fine, get through 80 of the wash/rinse cycle and then an extremely loud buzz starts coming from the door.
I just replaced the dispenser in April of 09 so I’d like to think thats not the problem, and in a post from 09 on this site I read where someone mesured the amps and voltages leading them to believe it was a control boards. Just lost my job, ain’t got no money so I’d rather not buy the wrong part:rolleyes: Thanks for the help.
