How to Troubleshoot & Replace Whirlpool AP6005780 / WP21001950 Motor Assembly

Replaced the motor. 

Replaced the motor, works like a dream! 

Change the motor assembly. 

Motor was ordered and replaced following the very helpful video on the site. Also installed the larger thrust bearing washer, having replaced the thrust bearing last year (also ordered from AppliancePartsPros.com) and noting a bit more play than I liked. After installing the new v-belt, which was ordered with the motor, the unit now runs quieter than it had in years! I had not realized how noisy it had become. I am very satisfied with the experience and have recommended this company to others. In discussing this with a friend he remarked that he had used AppliancePartsPros to effect a repair on an appliance and was grateful for the video as well. 

Watched a video on YouTube, ordered the motor from AppliancePartsPros.com and installed it. 

Had to replace motor 

Washer wouldn't start final spin and only made a hum which was followed by the smell of burning. Pulley's on the transmission, motor, and drain pump were all moving freely, I had recently replaced the belt so I knew that wasn't the problem, and I verified the washer was coming up off the brake when it was spun manually. Was able to replace the motor fairly easily (easier than replacing the springs for sure) and I'm now a few loads into a working washer! Video on this website for motor replacement was my best friend which is actually why I ordered from this site over another that would have saved me a few dollars! In either case spending the $140 for the motor was definitely cheaper than a $600 equivalent washing machine :-) 

I replaced the motor drive that fixed problem. 

Took about 15 mins. Swapped out the motor. Now I have my washer again. Easy peasy fix. 

Change the motor assembly with a new one and it fix the problem. The washer is working properly.
