Barry F Highlands Ranch , CO October 04, 2015 Appliance: Maytag Washer- Horizontal Axis MAH4000AWW Maytag Washer Mah4000aww: Spin cycle stopped working. How to replace Washer Wax Motor Actuator Kit. After much internet research (primary YouTube) as to why my Maytag Neptune washing machine's spin cycle stopped working, I ordered the parts I needed to fix it. Sure enough, it was a failed wax motor and a blown control board at fault. After replacing both parts, we have a functioning washing machine again. While I was at it, I replaced the soap dispenser's bezel and lid since they were deteriorating and now we have a "new" washer! I also replaces the thermostat in the matching dryer and we now have multiple levels of heat vs. just cool or very hot. Great to have a reliable place to get the parts I needed. I have used AppliancePartsPros several times over the past for +/- 6 years. They have always had the parts I needed and they have been there to answer any questions I may have before and during installation. I highly recommend them. 10 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
