kitchenaid stand mixer buzzing?

Hello,
Not knowing where to inform me, I address you to help me to resolve my problem. Then Here we are, I have a kitchenaid professional mixer 5 + (model KV25GOX OB) and the printed circuit is wretched. In the country where I live(lie), France, the approved repairers Kitchenaid cannot get themselves this circuit and knowing how to speak only about French I have difficulty in understanding(including) the American web sites.
Could use me thus by supplying me with information about the place where I can get myself this printed circuit in United States? Thank you very much of your help(assistant).

Cordially.
Madame MOREL
