Mixer stopped working and gave grinding sounds

  • Customer: brian from carlsbad, CA
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers

Following Replacement Part Youtube instructions, I disassembled the mixer and found what caused the sounds and prevented the mixer from operating. The worm follower gear had been ground down by the worm gear. I found that the shaft from the planetary gear had not been adequately greased and siezed preventing the worm follower gear from turning. The worm gear is obviously made of harder material and thus, was able to wear away the follower. I appreciate the your help which saved having to replace a perfectly good/expensive mixer. Thanks.

Watched the video. Ordered the parts. Watched the video again. Replaced the worm follower gear and bearings on the worm gear. Added grease. Installed new gear housing. Put it all back together and tested. Works like new. Now I get cakes and goodies again and have a happy wife who thinks I'm super handyman. Thanks

The repair is actually quite simple. The Snap Ring Pliers are essential. Make sure you clean out all the old grease in the machine and replace with new grease. The metal dust will act like sandpaper and destroy your new gear. There are several videos on YouTube which go through the process of repair and part replacement, I found these quite helpful. Good luck! DIY!!!!

Open the package with the new screw and it looked like the screw was wider. I tried it to see if it goes in and as long as you screw it straight in, there was no problem.

Gear Stripped

I had previously ordered several other gears after I found one of the worm gears stripped. After putting it all back together, the one major gear in the unit that I had not replaced because it looked fine, the bevel gear, also stripped. Learning experience: this is a unit worth several hundred dollars, so don't skimp on a $4 part. Once you work on this thing, you might as well spend a few bucks more and replace ALL the gears - even if they look like they are okay. Furthermore, if you only take 15 minutes to do this repair, as some on this site suggest, you are probably not cleaning the old grease carefully enough. Make sure you properly clean out the old grease to remove any metal from stripped gears, and use a good quality grease to re-pack the gear case.

Took housing off, removed computer board and disconnected speed control assembly from board. Soaked plastic slide in hot water and freed up mech. Discovered a crack in plastic slide from forcing it. Ordered new assembly and installed. TIP: Keep slide clean of substances that will jam it by cleaning occasionally with water. For a complete cleaning you will have to remove it.

Looked at the schematic for this model on Parts Select. Removed Aluminum band screw, removed the 4 screws that hold the top of the mixer. Lifted the top off. Removed 4 screws and lifted the gear case. Removed snap ring and took off tapered gear. Removed pin and removed worm gear. Picked out the metal, in the grease, from the old worm gear, using a magnet then inserted new worm gear and put it back together in reverse order. There was plenty of grease and didn't need to add any.

I unplugged the mixer, then I removed the Phillips screw holding the beauty ring, then removed the 4 screws that hold the motor housing together. I removed the housing top, and unscrewed the speed control switch. I marked each one of the connectors of the switch (there are 4) 1-4 then disconnected the speed sensor from the switch and the motor. Replaced the new sensor and connected that to the new speed control switch. reconnected the connectors to the terminals I took them from ( 1 - 4 ) screwed it into place. replaced the top motor housing, I screwed that back with the four screws. replaced the beauty ring and screw. plugged it in and tested it and it was like new

I have to thank you at Partselect.com. You happen to help me help other people. Now I have several people bringing me their Kitchenaids to me instead of sending them in. I replaced two worm gears on a Kitchenaid 6 and the Hall sensor on a Kitchenaid 5. Very easy to do. Next week I have another Kitchenaid 5 to replace the motor on. Thankyou again for having the parts I need
