Hello All,

OK, I have an Maytag Neptune, MAH3000AWW. A few years ago I replaced the machine control board and wax motor for the door lock. I also replace the Tach, Torque, and 24 VDC wires from Connector P4 on the machine control board to Connector JP4 on the motor control board. One of the wires had an intermittent open, so I just replaced all three. The machine faithfully worked after that for many years, then....

The machine will start to fill, then turn off. If I turn the dial to a spin cycle, it will drain, lock the door, then turn off with no spin. I opened her up and did the troubleshoot for Washer Fills but Will not Tumble, which lead me to the Drive System Diagnostics. This asked me to set the timer knob to delay, push the start button and confirm the delay light came on (did), then check the 120 VAC on the motor control board (all good), then unplug the machine, unplug JP4, plug back in and push start. The machine was supposed to tumble (didn't).

I checked the fuse on the motor control board and it was blown. So I replaced it. Then I went to do the same Drive System Diagnostics again. When I push the start button with JP4 unplugged there is a noise (like motor start up, but louder) and the fuse blows.

The General operation diagnostics don't really help from here....So where do I go next? Is this a replace motor and motor control board kind of issue??

Thank you in advance for your help.

Richard

1) try it again with the Belt removed
2) do you already have the newer Motor / Controller ?

Tried again with the belt removed...same result. Makes a noise that doesn't sound quite right for motor start up and the fuse blows.

I have the original motor and motor control board. The washer was purchased in 1998.

The motor shaft spins freely by hand, and the wash tub spins freely by hand as well.

Dumb question: I used a standard AGC - 10 250V(from auto store) fuse to replace the 10A fuse that was originally on the board. Wrong kind of fuse? Forgive me as I don't know a great deal about fuses and grabbed what I could find that looked right.

Another question: Can I directly power the motor to see if that is working right? I want to rule out the wiring harness as a cause.

no, it's actually a 3 phase Motor...
Fuse semms OK,
You could try a higher rated Fuse,
but I don't think that will help.

OK, so I checked the wiring harness connector on the motor, 2.5, 2.4, and 2.4. So that checks out.

I grabbed a 20 A fuse and had my wife watch the motor shaft while I turned the washer on (in delay mode with JP4 unplugged), it made a buzzing sound and she said the shaft twisted just slightly, then stopped. At that point the fuse blew.

So this leaves me buying new motor and motor control board, right?

Run the Basic Motor Function Test for Early Model Maytag Neptune Washers. If the drum doesn't rotate at 50 RPM, then you need to the motor and controller kit that GMF Reg linked you to.

Replacing the fuse on the board is always futile because it blew as a result of something else bad either on the board or on the motor.

Thank you guys! It looks like I am looking at new motor and control kit. I will get one ordered and installed. It's either that or a new washer...

Quick update: Motor & control board update kit arrived this afternoon. Took about 20 minutes to install and the washer is busy washing it's first load post repair!

A quick thank you to Repair Clinic.com. The part order was fast, efficient with a knowledgable salesman on the other end of the phone (description of the part asked for a phone call to confirm the part was correct for my machine...that is GREATLY appreciated). Shipping was as expected and the part was less expensive delivered to my door than anyone could do locally (checked mostly to see if I could get the part the same day without being charged too much so we could get to work on the laundry pile sooner...).

This is the second repair you helped me through on this washer. Calling someone in to fix the washer would have been so prohibitively expensive a new washer would have been purchased. You have now saved me from spending that money twice! You guys rock!
