4K5SSWH1 KitchenAid Mixer - Instructions

Replaced the speed control plate and phase control board and works well. Pay attention to speed control board spring and adjustment lever when reassembling.

I did some research and evaluated a modern day Kitchen Aid Mixer. Looked a the wire diagram and found out what items I needed. Ordered them from Partselect. Overall Mixer is updated and running. I made up some cookie dough with it. The Project took a few evenings due to rewiring the coils on the motor/armature and modifying the rear bearing bracket to hold the Phase control board (not OEM on 70's mixers). Then put it back together and adjusted the speed control.

1. Removed the mixer back plate Cover. 2. Removed the Speed Control Plate and retained spring, wires and ground wire. 3. Removed the old Speed Control Plate screws. Noted Control Plate pitted contact. 4. Removed old Triac Phase Control Board. 5. Removed old Governor. 6. Installed new Governor. 7. Installed new Phase Control Board. 8. Installed new Speed Control Plate and retaining spring. 9. Reattached Speed Control Plate wires. 10. Adjusted Speed Control Plate Screws and set mixer speeds from Stir to maximum settings. 11. Replaced Motor Brushes on left and right side of mixer. 12. Reinstalled mixer back plate cover.

Rather than duplicate previous repair works, I recommend going to this user site and follow their instructions: http://www.neilcrockett.com/mixer1.htm. Once you have done this repair, taking the unit apart is easier to perform this tasks. Order replacement Grease "Benalene 930-2" in the 3.3 oz container and be sure to use the full container to lather all around all the gear components so grease will be available to units for years to come due to heat build up under load. Too, the 3.5 oz container is made for one unit repair job and is available through Amazon. This grease is available on larger quantities if needed / desired. I did order both, a Worm Gear and the Worm Gear and Bracket as I wasn't sure of my mechanical ability to make this repair until I got inside the unit but the worm gear is easily replaced once you clean out all the old grease. The worm gear is a neoprene type gear with all other gears being metal. I assume neoprene is used as sacrificial to save other gears from breaking under loads and years of use.

Follow a YouTube video step by step

watched an internet video to see what to do. Unfortunately even after replacing the chip the mixer it still didn't work.

disassembled replaced part reassembled now works well

Was able to use the diagrams to figure out how to put everything back together. Would have been a nightmare without that as I took the thing apart without really paying attention to what went where. The hardest part was inserting a set pin that holds the Bowl lift arm, which fits inside the stand. in place. So new parts - $20, less than an hour of my time disassembling/reassembling, probably saved me $125 in repair plus a couple hours driving it to service place and picking it up. No brainer.

First of all I found the part in no time flat and ordered it early afternoon and it was at my door within 24 hours! My son was off work one day and I asked him if he needed a job to do and he said "sure". So I showed him the new part and where it goes and in less then 10 min it was working. awesome!

I removed the spring loaded brush screw on the side of my mixer and lost it the next day. I found a schematic of this part on your website and ordered the four pieces that make up the brush screw(?). They arrived in just a few days and I referred back to the schematic to put it together. I then popped it in my mixer, screwed it down, plugged her in and away we go! Easiest repair I’ve ever done! I’m a 70 year old retired lady and not very handy, but this was an easy fix! Thank you, PartSelect!

Skewer the screw in with my fingers,

I removed one screw on back, once inside mixer I removed the ground screw then pulled off the black and white push on caps, then I reversed everything to get it installed, very easy

I screwed the two screws into the place of original holes and Voila! it was repaired.

Removed the two screws that hold the bowl spring in place. Removed broken spring. Replaced broken spring with replacement spring. Tightened two screws that hold it in place.

removed old screws and latch, replaced it with the new. took just a few seconds. This is the first time i ever fixed anything. customer service was amazing
