4KSM150PSGR0 KitchenAid Mixer - Instructions

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.

Easy to locate part I needed (brushes)..great diagrams Thanks

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

Removed the old screw cap and installed the new one-only has 3 screw to remove and re install. VERY easy. Fits perfectly

Ordered new paddle beater, rmoved old beater from mach, took new beater from plstc bag, inserted into mixer in appropriate plc, turned on mixer. YES!!

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?

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.

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 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.

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.

I ordered a new wire whip and attached it just like it was the original. WALLA!!! Done.

I took out the worm gear and replaced it with the new one. It is important to have the correct punches that are just under the diameter of the pins.

After removing one screw at the top of the rear housing, and the housing you have clear access to the wire attachment points. I useg a very small screw drive to unlock the female disconnects from the male connectors.I disconnected and connected the wires one at a time to be certain I did not misconnect the wires. The ground wire is attached with a screw. The moulded strain releif is pushed onto the main housing cutout and the rear housing tabs slip into pockets at the bottom of the main housing. The screw at the top holds it is place.

This is the easiest repair ever! I removed the 3 screws, cleaned around the area with a sponge and kitchen cleaner and put on the new cap. The screws went back in easily and voila ! Done!

I looked on line found the product sent in information and 3 days later was in my mailbox,great service and ease of ordering. thanks marjorie
