KP2671-3 KitchenAid Mixer - Instructions

When I ordered a replacement assembly, I was sent a "new" replacement. As I had read up on your site to number the 5 wires BEFORE I removed them, this was a great idea. The new assembly was wired differently than the original board. Although no install instructions came with the new part, it was just a matter of connecting the NUMBERED wires to the new configuration. The first time I fired it up after plugging everything in, nothing happened! I removed all the plug-in wires and reinstalled to ensure I had not gotten a tight connection because of the plastic covers over the end connectors. On my second try, everything worked as advertised! VIOLA!!!! It was a bit tough because of the tight spaces within the motor housing and the new wire routing. Just take pictures of the area BEFORE you disconnect anything and you should do o.k., since I did. 20 minutes.

Found a kitchen aid repair video. Found your site for the part I needed. The connections were not like what the video showed but there were enough connector symbols that I was able to understand where they needed to connect. Marking the connections helped for making the new connections when the new circuit board came.

At first thought part was incorrect as the electrical connection tabs on the circuit board were not inline as the existing part. However, upon closer examination I realized that the same quantity of tabs existed on the new part and although not inline, were clearly marked the same as the original part. Unit was easily replaced and is operating just like new.

Remove covers, open gear box, remove lock ring and gears to deterime which gears were bad. Remove old grease, install new gears and pack with new grease.

replace worm gear

Removed old housing, pulled spring clip, slide on new gear and replaced clip. Put on new gasket and housing. Replaced outer cover. Done.

so easy to remove the switch. I first marked the wires, 1-2-3-4 and then removed them from the old switch. removed the old switch and replaced with the new one and plugged in the wires as per markings. tried it out before replacing the top and it works perfectly. no longer timid about effecting repairs on my own. the diagrams on the website were a great help. this is a great company to do business with. part was here in 3 days.

3d time in 20 years, but the mixer itself is built like they did 20 yrs ago PartSelect had the part in my mail box in *20 hours* from online order!

BUT - they changed the design so a power switch previously separate from (to the left of) the circuit board is now a microswitch integrated on the board, leaving you with ONE LESS WIRE.
Attached is the fix diagram & directions for the new design.

removed top housing, removed gear housing cover, removed all gears, cleaned out all grease, obtained gears and new housing cover, fit all gears in housing, filled with grease and put on housing cover.
Reassembled mixer.

Removed top cover of mixer which was very easy. Then marked the 4 wires so they could be plugged back to new switch correctly. Removed 2 attaching screws to remove switch and one squeeze connector. Installed new switch after plugging on 4 wires. Snapped squeeze connector in place. Reinstalled top cover.

Remove and replace gear case. Apply food grade grease secure with screws.

1. Removed the decorative band then the upper motor cover.
2. Removed the upper gear case cover. Found one of the two alignment pins broken.
3. Inspected gears.
4. Cleaned out old grease.
5. Repacked with new food grade grease.
6. Reassembled.

Could not get it properly installed. Had to take to a repair center for completion.

my hasband did the work and i an so happy it is working good for me now,

I removed the decorative band that covers the seam by removing 1 screw. I then removed the top portion of mixer by removing 4 square head screws. You will then see the gear housing in the front of the mixer. Remove the 4 screws holding that on. There are no spring that are going to pop out and you never know where they went, but be careful because there is a lot of grease and a gear that it just laying in there on the right side. You will see the stainless shaft with a couple on gear cogs on it. Remove the retaing spring from the shaft and pull the top gear off, it may be a little snug. You will then see the dowel pin, mine was sheared off but I could see where it was. Be sure to remove the broken pieces. Use the punch to knock out the remaining pin. Replace with new pin making sure it is evenly exposed on both side of the shaft. Replace the top gear, then the retaining spring, the the gear housing cover, then the mixer top cover and finally the decorative band. Be sure to unplug before you start. These mixers are expensive and expensive to have someone fix them. I ordered 2 pins because shipping is a little high and the pin is cheap. I fixed this for $17.00 total and have a spare pin.
