Mixer doesn't run

The lights come on but the motor doesn't start. I have removed all the screws I can get to but the mixer won't come apart. I would like a suggestion as to how to get it apart, or where I can get a parts diagram. I have tried several online parts listings with no luck. (my model is XAAS)

You can take it apart by removing the pin which is in the shaft that does NOT hold the attachments....... i got mine out with a nail set and a gentle tap or two with a hammer. after you remove that pin the portion that holds the attachments will slide down revealing three more screws and some gearing. if you remove those three screws....... the top will come apart (assuming you have removed the other four screws which are visible when the unit is assembled) and you will see the circuit board.

There's 2 short screws that you can see. on the shaft of were you put the attachments, there's a c clamp that you need to take off and there's a pin that you have to punch out ( be sure to save these parts ). once you get this off you should see the gears, on the outer side of the machine there will be 2 more screws but they will be longer( don't take the screws out that are in the gear area ) and the top should come off then. when you look inside, you should see a micro switch that is located where the two haves meet. sometimes there's a piece of metal that is held down by a brass screw that doesn't engage the micro switch. the way i fixed mine was to fashion a new piece. ( make sure that the piece engages the switch when you put it in the down position ). reverse your steps to put it back together and test.

    If you are not getting power, no lights, nothing happening, there is a fuse in the plug in. You have to follow the above steps, then take the back plate off by removing the bottom screws and 2 screws straight down from the top on the back side. The fuse will slide out from the bottom of the plug in by prying the lower back with a small flat head.

250 watts k45ss classic stand mixer doesn't run


My first guess would be the speed control plate. It has three screws in an upside down triangular shape. The two screws on top control and adjust speeds 1 thru 6, and often times just one screw being out a 16th of a turn will shut the mixer off completely. I would venture that when you were removing the two stud bolts you moved the adjustment screws on the speed control plate. Remember that even a slight movement can shut down your mixer, take a phillips screwdriver and turn the top left screw one quarter turn while the machine is on, it can start on you so don't be shocked and jump with a loaded screwdriver in your hand at the back of an electrical device, stay calm, if no start then try the left screw a quarter turn, if it does not start go to a half turn on each screw, if still no start turn thr screws back to the start place and try the bottom screw a quarter turn left and right, if you do not start by now, then something is wrong in another place, go back to the brushes and take them out and check how you put them in, these are the two most common problems with a no start mixer. If this does not fix your problem or get the mixer to start please come back here with more info. If you motor raced in the first place then I would suspect the phase control board, but when it came back to normal speed it leades me away from the phase board. When the phse control board goes out the mixer only works at high speed. So please let us know so that we can help further.

Kitchenaid mixer motor quit , I dont really see any thing wrong with the brushes.


Obtain a copy of the Repair Part List for your model from Kitchenaid.com.
Download a Copy of the Kitchenaid Service manual.

http://www.kitchenaidparts.be/centers/servicemanual/mixer.pdf

First, you may want to adjust the mixer's speeds:

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

Second, if the mixer won't run:
Remove the Control Plate Assembly (36), the Phase Control Board (39)
and the motor Governor Assembly (35). Inspect for loose connections,
burnt or damaged components. If they seem to look OK, re-assemble
them and test the mixer. If the motor still won't run, then I might suspect
a defective Phase Control Board (39).

Make sure the Speed Lever and and the Speed Link are in place
and operating smoothly. The two Large black screws you are referring to
are the Motor Brushes Caps. The Carbon Brushes are keyed and
designed to be inserted into the Motor Housing but one way. If you
insert them in wrong, they will not make contact with the Motor Coils
and you mixer will never run.

All you have to do now is adjust the mixer speeds (if necessary):

Remove the screw holding the End Cover and locate the three screws from the Control Plate.
All three (2 top left and right, and 1 bottom) must be adjusted.

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

I have a KitchenAid Professional 600 Series 6-Quart Stand Mixer, model KP26M1XBS, which no longer works. I was mixing pretzel dough and the mixer stopped turning. I initially just thought it overheated...


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.

My k5ss mixer will not start ,I remove the 2 screw on each side of the head, i put them back and now it wont start


Hi DENAULTR, I hate it when that happens. Those two “screws”’ are your mixer’s electric motor brushes. The slotted black threaded plastic parts are just the Brush Holder Caps and are the protective covers to the brush holder assemblies. They allow access to the brushes when they need to be replaced without having to take the whole mixer head apart.
From what you’ve described, I suspect that one or both of the brushes is (are) not seated properly when you reinstalled them. The brushes need to be installed so that they both seat correctly on the armature's commutator or you won’t get any ‘juice’ to the motor. See the illustration below:
9218969.jpg
I'd suggest removing them again and making sure the concave contact face rests completely on the armature’s commutator. If you've turned it 90 degrees too much, it won’t seat properly and you get no power to the motor.
It would also be helpful to have the Parts List manual on hand. If you're lacking one, you can download a PDF version Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case use KSM50P (Your K5SS mixer falls within this manual), and select the first file KSM50P.pdf (438.31 KB) listed under Parts List (4) and then check to verify this matches your mixer model.
Turn to pages 6 & 7, titled “Motor And Control Parts”, which provides an exploded view for the disassembly and reassembly of your mixer’s electrical components, along with all the part names and numbers. Locate Illus No 47, Brush holder assembly that includes Illus. Nos. #28, 32, 33, 34, & 46, and Illus. No. 29, Brush & Spring assembly respectively.
The Parts List illustration along with the picture above regarding the orientation of the brushes should get your mixer powered back up and operational. Good luck! I hope this helps. Howard, Burke, VA

My DeLonghi DSM800 when running sometimes stop for a second and then starts up again. It also seems to speed up at times and almost sounds like it is skipping a gear or something. Any ideas.


I had the same problem and fixed it.
  1. I took it apart, unplug unit, remove the small black cover inside the stand portion, 1 screw. Underneath you will find four screws with a white plastic wire junction.
  2. Loosen two screws and remove the black and brown wires which connect to the control panel with the dial attached.
  3. Remove rear attachment cover, front top cover, and front delonghi cover.
  4. Remove top three screws where the blender attachment goes. Now remove the aluminum cover that covers the entire top.
  5. Slip belt off. Remove three screws with plastic washers that attach motor to chassis.
  6. Remove 2 torx screws that are located next to metal bar that keeps top half from swinging too far from bottom half.
  7. Now you can pull the motor out and the control panel with the dial. Remove the three slip on electrical connections on the control panel and reinstall. Carefully remove the two slip on electrical connections on the motor and reinstall.
  8. Re-assemble and test unit.
I thought I had a problem with the control panel or the motor, as it turns out the connections were the problem. Carefully removing them and reinstalling them solved the problem.

Kitchen aid k45ss classic unscrewed black plastic screws and springs on housing and replaced and now it won't run


Hi, JDMCIN. I hate it when that happens. It seems that power is not getting to the armature from the brushes so I would suspect that one or both of the brushes is (are) not seated properly. I'd suggest removing them again and making sure the contacts are facing in the right direction to contact the armature’s commutator. The concave contact face should be resting completely on the commutator. If you've turned it 90 degrees too much, it won’t' seat properly and the motor doesn’t get any juice.

Took apart, pull magnets from sides, now the thing


ECARRERO2004 - Those 'magnets' you removed from the sides of your mixer are the electric motor brushes that provide power to the commutator/armature assembly so your motor runs. Did you remove the brushes to replace them or were you just inspecting them? I'd suggest removing them again and making sure the contacts are facing in the right direction to contact the commutaor. The concave contact face should be resting completely on the comutator. If you've turned it 90 degrees too much, it wont' seat properly and you'll get no 'juice' to the electric motor so it won't start. I hope this helps - Howard, Burke, VA
