How to Troubleshoot & Replace Whirlpool AP6007406 / WP240775-1 Motor Housing Seal

I purchased a new speed control plate, governor, phase control board and seal. As long as I was fixing it, I just changed everything. As I was removing the old, I found one wire had broken off the control plate and had to replace the flag connector on the wire.(white wire) I followed the videos and they were great!! I would not have known about the speed control adjustments and would have taken the screws out without thinking. The repairs went easy as the video. I checked the adjustment and had the right revolutions at low and 6. However I did not have any different speed above 6. It seemed to be dragging a bit. I took off the planetary and cleaned and applied new grease, put it back together and then had the higher speeds. Magic?? Back in business!! I ordered the parts on a Tuesday morning, they were shipped within a short time, I think less than a hour and had them in my hands the next day. Hard to believe they came so fast (FED EX) I am glad I found you! Thanks! 

I replaced the Board-Phas and speed control plate since power was not making it to the motor. When I received the speed control plate it had nuts on the upper screws with springs, since my old one didn't have nuts I assumed that the nuts were to keep the springs on until installed. After putting it back together, I noticed that though it worked, the first two settings did nothing. Now, guys, I was desperate, OK. I downloaded the service manual and read it from front to back, and when I got to the part where you remove the speed control plate, it said to loosen the lock nuts, (lock nuts?). On the replacement speed control plate you require the nuts. I put the nuts on, adjusted the depth and we're golden. Thanks for the parts and speedy service, Pat 

Replaced the armature bearing at the front of the mixer next to the gear case and replaced the gasket on the gear case. 

I ordered the armature and field-asm cause I did a test on the armature by connecting it directly to the power line and did not have any movement. Upon changing the armature and assembling the brushes, I realized one of the brushes was getting held up. I opened up the edges of the brush holder and that did it. I knew nothing seemed wrong with the parts I took out so I concluded that was the problem because I had just bought it, used it only twice and it stopped working. 

I replaced the speed control plate. Part # WPW10119326. Replacing the plate was dead easy. Speed adjustment was a bit tricky. I referred to a YouTube video for guidance. https://www.youtube.com/watch?v=pUo_ZU5xh3o 

Replaced the speed control handle in various other parts, the videos that are posted with the website are incredible and they tell you exactly how to do it very easy to repair. 

Replaced winding and armature 

Easy fix by replacing the phase control board. Plenty of YouTube videos showing how it is done and is really very easy to do.
