How to Troubleshoot & Replace Whirlpool AP4010145 / 12002039 Drive Motor

Basically rebuilt the washer from the ground up. Spent more money than a new washer but we have been so happy with the way this machine has worked over the last 19 years figured it would be money well spent. 

This was on a Maytag Neptune mah5500bww model. I watched the short video and the repair was done in less than an hour. It's a vary simple repair with minimal amount of tools. Narrowing down the problem using the washers code system took about the same amount in time. I had already used an ohm meter on the motor windings and knew where the problem was. At that point I removed the motor control panel ( bottom front of unit ) and on inspection found a blown fuse, and a couple of resisters . No fixing this. I found the parts package with Appliance Pros at a very reasonable price. Also bought a new drum belt, which I didn't use , as the old one looked like new. On the shelf it went for now. I spent less than $ 300 and the unit is good as new and quieter. Best of all, my lovely wife is happy and I am the envy of her aerobics class. Thank you . PS: The part came within 2 days. Outstanding! 

After researching repair histories, we concluded that the motor and or motor control board were the most likely failed parts. Fortunately Appliance Part Pros sold a conversion unit for this model that included both items as a package. The price at just over $250 was reasonable. We order on a Monday and Fed-ex dropped it at our door Weds AM. Removal and replacement of both parts took about and hour and a half. The instructions provided were helpful and accurate. The washer is working probably better than new. We were quite satisfied. 

I called appliance parts pro and tell them about the sound of the washer when it is on agitating mode. A technician tell me that it is the motor that about to go out and ask me to give the model number. At that time i did not have the model number ready. After 20 minutes i pulled out the washer to get the model number and i called back another tech was on the phone and he help me to get the motor.I order the motor and a belt but the belt is short there is no way that it will fit.Anyway i pull out the old motor and compare it to the old one, the wire harness is different, the video shows it is simple just plug in the motor and go. In my case i have a new control board and the motor with new wire harness. But with the help of customer service and the technician i manage to get it back together and it is running good. THANK YOU FOR A GREAT SUPPORT AND PATIENCE OF CUSTOMER SERVICE OF THIS COMPANY. IT IS A TOP NOTCH SUPPORT AND SERVICE. 

I Diagnosed it as a bad drive motor. Confirmed with www.appliacepartspros.com's live chat tech on what part number I needed. Ordered a new drive motor from www.appliacepartspros.com. Two days later it was at my doorstep. I watched a video to familiarize myself with the motor removal and install procedure. Not only did I get the motor for a very fair price.( I did shop around ) But It came with an upgraded computer control module. Also a very detailed and easy to follow set of instructions. I was an appliance tech but have since changed careers. So I know what I'm talking about when I say my experience with this company was great. My washer hasn't worked this good in a very long time. It spins so fast and the water is so extracted from the cloths that my dryer times have been cut in half. 

Replaced the motor control board & main motor 

Replaced motor & control board with new replacement ones. Machine runs and is much quieter. 

Replaced motor and control board with a redesigned conversion kit 

I ordered the door latch assembly and that was so easy to replace and worked perfectly. I also ordered the motor drive kit that came with the control board. Installed the new control board kit and the motor and tested the spin cycle, but the tub wouldn't turn. After 40 minutes of going through all the test cycles (which we found the paper in the top where the main control board is) Finally figured out that you have to have the door attached and closed so the door lock can lock and then it would spin after it locked the door. Thanks so much for all the information on your site, so helpful. 

Replaced motor and motor control.
