Tip & How-To about Food Mixers

How to repair a KitchenAid mixer.

If your KichenAid mixer doesn't seem to have the power it once had try the following repair procedure.

More than likely the armature needs to be cleaned if you have made sure that the brushes are OK. The brushes are acceptable if they have 1/4 inch of carbon left. Disassembly of the unit is not that difficult.

First remove the screws holding in the brushes and remove the brushes. Make a note of which direction the 45 degree off set faces or you will have to dissable the entire unit to get the brushes in properly. Remove two screws from the rear of the unit holding the cover between the two halves of the unit (top and bottom). You will need to remove all the screws on the underside of the unit. Approximately 6.

The shaft located vertically has a pin in it which needs to be driven out with a punch/hammer. Then a "C" clip must be removed form the shaft to remove it. If you do not have a "C" clip pliers you can get them at most automotive parts distributors.

Next pry the bezel off around the exterior of the shaft which will expose about 6 screws which need to be taken out. Now you can remove the head assembly as well as the top of the unit exposing the motor armature. When reassembling this drive unit use some Loctite on the threads of the screws to prevent them backing out. This is a common problem with these units.

At this point you should be able to see how burnt the armature is. Using crocus cloth (very fine emery cloth) available at any home improvement store such as Lowes or Home Depot, clean the armature until it shines.

Clean the armature with a solvent to get rid of any filings or debris that was left from the cleaning process and wipe the entire unit clean.

Reassemble the unit and it should be as good as new. Remember to insert the brushes the proper way or the unit will not work. They are keyed.

Thanks for using FixYa and for the great rating.

kitchenaid wont start


The possible problems could be in no real order>>>
1. your power outlet in your house
2 the power cord to the mixer broken or shorted
3 the speed control plate inside the mixer needs adjusting or replaced
4 the carbon brushes inside the motor head of the mixer need replaced
5 the armature a motor part
6 the stator a motor part
The first four are easy fixes the last two will require a full tear down. but there are lots of things to test first. let us know.

kitchenaid mixer won't run changed out brushes and have changed them out in all 4 different positions


The brushes need to be seated onto the armature. Try going from off to high quickly and tapping the motor housing. Once the motor starts, let it run for 15 min plus to seat the brushes. Keep clear of or remove beaters whille trying to get the moror running. In brief, the brushesaren't making good contact with armature. Good Luck

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.
Good luck, I hope this helps. Howard, Burke, VA\
