4KV25H0XBK5 KitchenAid Mixer - Instructions

The repair was easy, I only had to order new gear assembly parts and to replace the associated worn parts (shaft, pin, and gears).

I followed the instructional video closely. My old circuit board was labeled and laid out slightly differently than the new one, so in addition to labeling the wires with "color" or "motor" label from the old board, I also made sure to label with more identifiers that were included on both boards such as "P1" or "P2". Once I labeled the wires with all the information, removal of the old board and installation of the new board was straightforward. This isn't the first repair I've made on my KitchenAid but it was by far the simplest.

Removed 2 screws holding the switch unplugged the one at a time.
opened the gear box cover 4 Philip screws, cleaned out the grease
removed the pinion gear, removed pin, removed the planet gear assembly replaced gears in reversed order greased it up put gear cover back on and tested worked great.

Thank goodness for YouTube. Pretty much followed the process of taking it out. Was easy, but having a video made it a bit simpler.

using Phillips screw driver, remove 5 screws - take off cowl (cover)l. remove 2 screws holding speed control assembly
unplug old speed control assembly (4 plugs) and plug in new speed control unit - reassemble cowl .

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 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.

Taking apart the machine is really easy. I was worried the grease would have spilled all over the places, but when the machine is cool, the grease is solid, so no spill. Replace the parts is quite straightforward, and there are plenty of tutorials on line. The only tip is that the grease used by KitchenAid is dark, and it is not easy to see all the small parts when you take the gearbox apart, so pay attention at what you do and at what you throw away... when I got to put it back together I missed a special concave washer which must have been trapped in the grease. Other than that... it has been an easy repair, the mixer is back up and running and I saved a ton on $$$
