Why is kitchenaid mixer making noise

It was three days before Christmas, and my to-bake list was long. Cinnamon buns, squares, cheesecake, cookies, truffles, etc etc etc… I was kneading a loaf of bread in my KitchenAid Stand Mixer when it clunked and the dough hook stopped turning even though the motor had not stopped running.

I raced to turn off the mixer and, of course, immediately tweeted my freak-out. Oh no!! What do I do? KitchenAid , being the wonderful company that they are, emailed me straight away — I did a campaign with them this fall so they knew who I was. I checked them out online and found reviews that were less than favourable when it came to their track record with KitchenAid mixers.

I took to Twitter and found the same reaction there to this service provider. All other parts in the machine are metal, but the worm gear is made out of plastic as sort of a fail-safe to protect the motor. If the gears got jammed and all parts were metal the motor would burn out in a hurry. They cleverly made this gear out of a tough plastic so that when the gears jam the worm gear takes the brunt, breaks, and the motor can keep running without melting down.

If the motor had burnt out, we definitely would have been talking about mixer replacement. He made it look straight-forward, though I know that he was intimidated about the project as soon as he saw the service manual instructions. It took less than an hour for him to confirm that the diagnosis was correct — the Worm Gear had been stripped. We have lift off, ladies and gentlemen!

A video posted by jennvb jennvb on Jan 10, at am PST. Yet when I replace the speed control board, there is no change in the performance. Clearly the speed control board is not the problem. Yes I did adjust the upper screws in to slow and out to speed up, and the bottom screw as well. No significant effect. Mixer "rolls" at any speed; not keeping an even speed. Any recommendations?
