My stand mixer's motor runs but the blades don't turn to mix the food

go to youtube type in ajustment on kitchen aids and it will show u step by step hope this helps

Are you sure there's power in that wall outlet? Try plugging something else in there

HI.Let me jusk ask if yiou also tried to connet to another socket.Let me just clarify that the motor itself did not work /rotate as well.Prior to that situation,have you tried to mix more than what is the capacity of your mixer.If possible motor was overworked/that's why its coil was burnt.There. are possibilities then. First might be that the mixers terminals inside will no longer engaged properly that's why it opens the circuit.Second the motor isn't working because the rotor and armatures coil was burnt because it runs beyond its maximum wattage capacity that's why it draws much current beyond the rotors coil capacity.Did you mixed something heavy.the motor works heavier the last time you used the unit?

Remove the Gearcase Motor Housing (1) & the Transmission Housing (7)
Remove the 2 screws (23) holding down the Motor (2) and lift off way from
the Worm Gear (17). Test run the motor by itself at different speeds.
If it runs fine then it's time to inspect all the gears in the Transmission
Housing(7). Remove all the brown Grease covering the gears.
Pay attention in particular to the teeth of the Worm Follower Gear (19).
(the Bevel Gear (21) sits on top of this gear)
They should not be worn out or chipped. If they are then this is the source
of the noises you're hearing (the Worm Gear is grinding away the teeth of
the Worm Follower Gear). Once the Follower is replaced, your mixer will
be just as new again.
Please Note that this replacement is not an easy task. You need the right
tools and don't use a hard object like a steel screwdriver to pry out the
Planetary plate (15) from the beater shaft. Before re-assembly, use only
fresh new Food Grade Grease from Kitchenaid (the old grease may contain
metal filings from the worn out gear that will damage your new one)

Don't worry about the Worm Gear for now. You have to make sure that the Motor
is fully functional by itself: Remove the Transmission Housing Cover (4 screws) and
the two screws holding the Motor down. Lift the Motor off the Worm Gear and set it
on the side (be careful of AC voltages from the Motor and Control Assembly).
Select Stir setting and observe the motor shaft. Is the Motor running? If it is,
Select other speeds to see how the motor performs.
With the motor now fully functional, you can now check the Worm Gear Follower
for worn out/broken teeth. Remember the motor drives the Worm Gear, it then in
turn drives the Worm Gear Follower (you may have to remove the grease to see it)
The Bevel Gear sits right on top of the Follower and drives the Attachment Gear.

the motor brushes are worn out and the bushes are worn allowing it to "pole "out
the fix is a replacement unit

worm gear is borken. buy new plastic gear it cost 25

If it is the worm gear then the planetary will stop turning when there is a load on the paddle but the motor will continue to run at the speed you set it at. I'd be checking the carbon brushes, checking that the field assembly has not loosened up a bit and then I would see if the speed control plate adjustment screws are loose. I'd then reset the speed and see if it stays as it should be.

You hopefully broke a keyway. Which is usually the case. (The key on the shaft that engages the motor worm gear is the place to look. Sometimes the center shaft gives way. Check all three gears.

The transmission uses grease. So "taking a look at it" is not a easy task.
