This morning I finally fixed the speed control switch on my 5 year old KA. Scary!!!!!!!!!! but I was desperate, and didn't have an extra $100 to have it done professionally. YouTube was my savior as usual.
https://www.youtube.com/watch?v=VeCiivPt7hk This guy is the best teacher, and very slow and concise. The cool part is that I could go at my own speed. He'd tell me what to do, I'd pause the video, and do it. After a half an hour my speed switch was fixed by ME. NO COST. All I had to do was tighten the tension screw which is housed in the motor. Might sound complicated, but it wasn't. If it wasn't my first time opening the mixer it would have only taken 10 minutes at the most.
He has many more videos on fixing problems with the Kitchenaid. Such as awful noises, and not spinning to name two. My only other advice is to do this when you know you won't be interrupted. I was sweating bullets thinking I would ruin this expensive machine, and didn't want to be to be distracted
Hope someone gets as much out of it as I did.
