Mixer bowl was slipping off the base when in use

  • Customer: Dean from Fairfax VA
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers

Replacing the base retaining bracket(what KitchenAid calls the screw cap) solved the problem immediately. The entire replacement effort took no more than a minute requiring removing 3 screws, discarding the old base, putting in the new one, and putting the screws back in. PartSelect was very easy to do business with. They shipped the part the day I ordered it and it arrived as scheduled. Can't be easier than that.

Plastic knob on speed control lever was lost

  • Customer: REID from BELLEVUE WA
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins

The knob was attached to the new lever. I began to disassemble the mixer case so that I could replace the lever. However, it soon became apparent that this would be a major project involving many components and potential problems in getting the unit back together. Since all I wanted was to replace the knob, I simply knocked it off the new lever and forced it onto the old one. It is hard for me to understand why Kitchenaid would not make just the knob available.

Remove the mixer head from the base by removing the 4 Phillips head screws. Pry off the ring around the rotating part with a flat head screwdriver. Punch out the pin holding the rotating part and remove. Remove the trim strip by removing the two Phillips screws at the rear of the unit. Remove the 4 screws at the bottom of the mixer head. Carefully separate the bottom of the head from the top using a flat screw driver. There will be the power wires connecting the top to the bottom of the unit. It is best to disconnect these wires to avoid breaking them during rest of the procedure. There will be a lot of grease in the gear box of the mixer. The assembly holding the damaged worm gear can now be removed by removing the three screws holding it to the bottom of the mixer head. At this point I removed the grease from the worm gear assembly to allow better inspection. Punch out the pin holding the worm gear to its shaft and remove the shaft. The worm gear is now free and can be replaced. Add some extra grease to the new gear and reassemble the mixer in the reverse order.

Mixer quit running

  • Tools Required: Screw drivers

I discovered the brushes were worn, and one side had broken off and lodged against the armature.I got lucky as I removed the brush caps and the sleeves the brushes fit into (simple job) and was able to hand turn the armature so the pieces fell down into the bottom of the mixer housing.After removing them, I replaced the brushes and the mixer runs like new. Thanks for the fast delivery AND more importantly, the right part. Steve

Motor would not turn on

Initially removed carbon brushes then inserted the new carbon brushes. The motor still did not turn on. Then I removed the brushes again, used a flashlight to look in the hole where the carbon brushes are installed. I noticed that there was a square notch on one side of the hole. I then reinstalled the carbon brushes, ensuring that the beveled side of the carbon brush was installed so it lines up with the square notch. This allows the carbon brushes to touch the motor. I turned the unit on and it worked.

Fast speed on every setting. No control of speeds.

I removed the cover off the back of the mixer. Carefully remove the cardboard gasket around the outside edge. Unlock the nuts that hold the two adjusting screws. Count the turns to remove each screw in order to keep the right adjustment. Pull the plate away enough to remove the control board. There is one long and one short wire that gets plugged into each side of the plate. Watch the location of each wire to make the right connection. Reattach the screws to the proper position. Then install the gasket and rear cover. Check for proper operation.
