My Kitchenaid Classic Mixer no longer ran at the low speeds but only at the #4 setting and above. I replaced the Speed Control Plate and the Phase Control Board per the video with only one problem. When removing the spring end, the spring slipped from my needlenose plies and jumped out of the hole inside the mixer. Re-attaching the spring inside the mixer was an hour-plus-long chore since you can’t see the hole inside the mixer and the spring has to be turned up at a 90-degree angle to be inserted into the hole so that it can lock in the hole. I solved this by bending a #14 copper wire (which is easily bent) with a 90-degree gradual bend and inserting it inside the spring, then I was able to position the spring inside the mixer and insert the spring up into the hole, and carefully slide the copper wire out of the spring. This took many tries but was doable. Other than the spring ordeal (which was my fault), the repair was easy and the mixer now operates at all speeds.
