speed control went. The beater would fly in any setting

I carefully removed the cover of my mixer. I first made sure that all of my part numbers corresponded, then I labeled the 5 wires that needed to be disconnected. I then disconnected the wires, removed the two screws holding the part in place, switched out the old for new, reconnected all of my wires. Mades sure everything looked tight, and put my cover back on. Works like a charm. I cried because what I really thought was going to be a $200+ fix, ended up costing me less than $50! And it was so easy.
