My kitchenaid stopped moving

My husband looked at youtube to figure out what the issue was. He saw a video that identified that the likely problem was the worm gear. My husband took the kitchenaid applicance apart, as he saw in the video. We ordered the part, it took less than a week to arrive. He rewatched the video that demonstrated how to put the kitchenaid mixer back together. It's a bit messy due to all the packing grease, but a pair of nitrile gloves, paper towels, and an old rag help. We put a garbage bag over the appliance after it was taken apart to protect it from any dust and my curious cat. We let the kitchenaid cycle for about a minute to make sure the gear was greased. I haven't used it to make bread yet, but I'll do that soon. Thanks for supplying the part that saved us at least one hundred dollars and TRY to get a person who will repair small appliances.

Neither motor brush popped out with the spring as shown on videos. Both appear to have disintegrated in part and had to be chiseled out delicately using and ice pick and tapping gently with a hammer. This left a carbon powder and pieces of the old brushes on the counter. Inserting the new brushes was as easy as shown on the video.

Knob fell out of the front of the mixer into the bowl and jammed the beater. This caused the motor to strip the plastic worm gear. Open unit to investigate and found about 4 teeth missing out of the worm gear. Ordered a replacement. Installed the new gear once received in about 30 minutes. Wife is now happy again. Just need to make sure you pack enough gease into the new gear before reassembling the unit.
