3KSM150PSTMH0 Whirlpool Mixer - Instructions

I watched the university of YouTube videos, and followed their instructions.

Removed the rear cover to inspect the speed board. Replaced motor brushes and noticed the motor body nuts were loose and 1 was completely off. Cleaned up speed board and replaced the motor body nuts, tightened with nutdriver, adjusted speedboard governor screws and with new motor brushes worked like a charm. The very rough sounding motor noise was gone and the mixer has not operated so quietly ever.

replaced gear, and brushes.

Followed web site's videos. One step left out of video.

Took each area apart. Replaced the gear and reassembled it.

Used youtube movies to disassemble the mixer and found that the gear was stripped. I kept the screws in labeled ziploc baggies so I wouldn't forget which screws went where. Once the part arrived, it was very simple to replace the gear. I regreased the mixer and then reassembled. The trickiest part was how greasy everything was! It was also hard to get the pin through the beater hub - I found a video that suggested using a very slim screwdriver to thread the hole before inserting the pin. This was the most involved part replacement I've done on my own, and it was very satisfying to get my mixer back in working order!

With a screw driver remove the screws holding the old base in place. With a flat head screw driver carefully pry and remove old mixer base. With 600 grit sandpaper clean and make smooth any burrs or rough spots in the mixer base recessed area. You can use some light grease and coat the outer edges of new mixer base and place in the now cleaned mixer base recessed area. The new base maybe a tight fit and not be fully seated in the recess. If a tight fit, place the piece of 2x4 piece of wood over the new part that is in the recess and carefully tap the base home using the sledge hammer. Check to see, if the base is fully seated. If not fully seated, tap again When fully seated replace the screws. You may have to adjust the height of the stand mixer head with mixer paddle attached for proper clearance between bowl and paddle. See your mixer manual for adjustment procedure

I watched a short video on replacing the worm gear, although I did not know what the problem was until I watched the video. after the video ended I took the mixer apart and found the problem located a parts number an placed my order. got the part in one week put in the new part in about 20 minutes and it work like new. and the price was very reasonable

I watched a YouTube video all the way through, then watched each segment and followed along with the video. It was messier than the professional repair guy, but it worked out fine. This is not a difficult repair when you can watch a video and follow along. It saved me about $130.

Removed three screws and lifted out old part. replaced with new part

Removed old plate, screwed in new plate and works like new! Was so happy I wouldn’t have to replace my 30 year old mixer.

I simply inserted the new beater into the mixer to see if it scraped the sides of the bowl. It fit perfectly and didn't scrape the bowl like the old one did.

Repair is very straight forward. Remove the existing plate by removing the three phillip head screws. Use a regular screwdriver or knife to pop the plate off. (I cleaned the area while I was there but probably not necessary) Position the new plate with the screw holes lined up. Press down to pop the plate into position. Install original screws and tighten. You're done!

followed the emailed instructions from your company
worked perfectly
thanks

Tried new brushes but alas it looks like it was a controller. Wife needed it asap so Ii bought her a new one. Service and delivery were quick but couldn't wait for a second part to try and repair it again.
