We have a 6 quart mixer that has been wonderful. While mixing dough yesterday, the hook stopped spinning although the motor kept running. It seems to spin when there is no resistance, but as soon as the slightest pressure is against the hook or attachment, it stops moving.
Motor seems to be burning out.

Hi. Stop using your mixer. If your mixer is still covered by warranty, call Kitchenaid Customer Service, they are very good with warranty repairs.
If your mixer is out of warranty, remove the silver band that surrounds the top of mixer. Remove the top cover. At the front of the mixer, locate the transmission housing which is now exposed. Examine this housing carefully for cracks. If you find cracks anywhere in this housing, you have found the under-engineered plastic transmission housing. Kitchenaid's replacement housing is made of metal. Your plastic housing has no business being in a mixer that is marketed as being able to mix bread dough. It cannot!
If you're confident that you can make the repairs yourself, go to the Kitchenaid website and download the parts drawings. Remove the Trans. housing, remove the worm gear shaft assembly which is driven by the motor.. Remove and save as much grease as necessary to thoroughly inspect the worm gear. Inspect the worm shaft bearings. Look for cracks, or missing pieces on the bearings. Look for crunched cogs on all gears. Be prepared to wait at least a month for your parts to arrive after you order them. The replacement grease should be Shell Darina 2, or Chevron FM ALC EP 2.
If you're not confident about repairing this yourself, call Kitchenaid and determine the nearest "approved" repair shop.
You may be able to pressure Kitchenaid to pay for the damaged parts in your mixer. They are still installing these plastic Trans. housing on new mixers. Insist on a metal cover when replacing. Apparently, Kitchenaid feels no shame in their manufacturing process, and will not issue a recall notice for these housings. They are substandard at best.
If you found this solution helpful, please rate it. Good luck! ricardok45.

Sounds like the shear pin on the planetary shaft has sheared off. Has the mixer been subjected to a heavy load. Remove the planetary and see if the shear pin is intact otherwise you may have to open up the transmission.
