Title: MAH4000AWW burt out R28 and R29
Post by: tranibob on October 06, 2007, 05:28:13 PM
Hi all,

First time here and can't believe how great the information is!! My girlfriend has a Maytag Neptune MAH4000AWW that quit spinning. After doing a little reading i was sure i would find the R28 resistor fried but nope.

Turns out the problem is in the motor control board at the bottom of the washer. I can visually see that what looks like a resistor at R28 and R29 are completely melted. The glass tube fuse is also burnt.

What i am looking for, is first the value of both resistors. I saw the link for a new motor control board and might end up buying one, but was going to try and impress the girlfriend by just replacing those components first if i could  ;)

My other question is, was this caused by the same wax motor that is talked about everywhere or something elxe? No signs of damage at all at the upper control board.

Lastly help this automotive transmission specialist here that knows nothing about appliaces... why is it called a wax motor???

Thanks in advance,

Robert

That could be a tough one. If I dig around the shop I maybe able to come up with a old board I could look at. I would guess you won't have much luck repairing the old motor control board.

The new motor control board will come as a repair kit with a new style motor and control board. You will need to replace both the motor and board as a set.

The wax motor has nothing to do with the motor control board.

If you did not find it already here is the Service Manual (http://appliancejunk.com/forums/index.php?action=tpmod;dl=item15) for your washer.

Thanks for the quick reply. I did download the manual and reading through it right now. I also search the web and found out what a wax motor was.

So the was motor did not cause the failure.. now i have to figure out what cause this.

It was ether the motor went bad and took the board out or the motor control board just went bad.

Thanks for the reply,

Either way it's not that expensive to get a new motor with the board ($217.00) so i went ahead and ordered it online. I ordered the updated wax motor a the same time to prevent future failure.

Thanks again for the help, this site is GREAT!

If your old wax motor has a brown plunger, your controller board (or parts thereon) could be blown.

the new wax motor should have a black plunger
