Repair was easy. Remove the seal ring with a flat blade screwdriver and drive out retaining pin. Pry out lower unit using two screwdrivers, one on each side. Once apart, use spring clip pliers to remove snap ring. Pull out shaft and replace. Clean and lubricate as you reassemble in reverse. Google the model number to get detailed instructions.

worn teflon worm gear

  • Customer: Frank from Bethlehem PA
  • Difficulty: Really easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers

it was a kitchen aid dough mixer, had to take the top portion off and replace the assembly with a new one that holds the teflon gear. You can purchace the gear only and it becomes less expensive, but at the time I didn't take the chance cause the greese was there and didn't want to take a chance. Its a simple repair by removing some cotter pins and phillips head screws.

Corroded speed control plate ( full of flour). Had used the mixer for grinding deer meat and lost the slow speed. Flour would fly up in my wife's face.

I just thought there had to be a way to replace a component to correct the speed problem. I've never worked on a mixer before, so I thought it would be a challenge. Actually the repair was fairly easy. Make sure the unit is unplugged from AC. I removed the back motor cover with one screw and removed the end seal. I compared the parts on the mixer with the diagram provided at the Part Select website. I then ordered the parts. When the parts arrived 3 days later, I removed the Speed Control Plate ( 3 screws) and Phase Control Bd (1 screw) as one Assy. Removed the old Governor and slipped on the new one. Assy the new Speed Control Plate and Phase Control Bd comparing wiring and screwed them back to the unit. Removed the two motor bushes by unscrewing the side black motor brush holders and inserting the new brushes. I tried powering motor and nothing happened. I thought, great, now what did I do? I found out that you must make sure the brushes actually touch the armature otherwise the motor doesn't run. The gears are worn from grinding to much deer meat and my wife says no more. I've ordered new gears and looks like that job, too, will be easy to repair. Adding these parts is alot cheaper than buying a new unit and it will run like new. Not bad for over 10 years of usage.

Nothing would happen when we turned it on...

The brushes on the inside of the motor were destroyed. We thought that it would be easier to just replace the brush holder and the brushes, however, the brushes were easy! and QUICK! The brush holders...not so much. We had lots of problems getting the brush holders into place because of a metal piece that had to fit perfectly on top of the brush holder. It made it easier when I held the mixer upside down (we dissembled it) and my husband did his magic on fixing the brush holders. Pray that you won't need to replace the brush holders because it was NO FUN...but the brushes were QUICK AND EASY :)

I was very happy with the customer services department and the support I received in identifying the part I needed for the repair. I received an email confirming my order with all details. I do wish you had a more cost effective shipping alternative, like Priority mail.
The repair went well and the mixer is back in business, for making those Chocolate Chip Cookie and brownies if you know what I mean.

Thank you

The part fit great! PS. I may need to buy a gasket to go around my refrigerator door. I have an Amana Model #THI1853W, Serial No. 9502301998. Do you have instructions on how to install this gasket?

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.

My kitchenaid stopped moving

My husband looked at youtube to figure out what the issue was. He saw a video that identified that the likely problem was the worm gear. My husband took the kitchenaid applicance apart, as he saw in the video. We ordered the part, it took less than a week to arrive. He rewatched the video that demonstrated how to put the kitchenaid mixer back together. It's a bit messy due to all the packing grease, but a pair of nitrile gloves, paper towels, and an old rag help. We put a garbage bag over the appliance after it was taken apart to protect it from any dust and my curious cat. We let the kitchenaid cycle for about a minute to make sure the gear was greased. I haven't used it to make bread yet, but I'll do that soon. Thanks for supplying the part that saved us at least one hundred dollars and TRY to get a person who will repair small appliances.

motor brushes worn out

Neither motor brush popped out with the spring as shown on videos. Both appear to have disintegrated in part and had to be chiseled out delicately using and ice pick and tapping gently with a hammer. This left a carbon powder and pieces of the old brushes on the counter. Inserting the new brushes was as easy as shown on the video.
