I need either the schematic for the control board for a Maytag 'Neptune' Model MAH3000AWW washing machine, or the board itself if I can't get the schematic.
Can anybody be of help? Maytag wants to sell me the board: toooo expensive.

Hi,
I doubt you will find the schematic for the control board....I doubt Maytag even has it as the part is made by someone else for them.
What is wrong with yours??

Posted the question for a friend who is off on a short trip, back late today (he's got a background in electronics). I'm not sure exactly what the symptoms are, but will post them after he gets back. Thanks!

Hi,
Great!

Jeff:
Here's what he gave me.
No +24 at P3-7 to motor control (measuring to neutral ref.)
+24 is measured across large filter cap at output of bridge diode on central board.160 Ohm is measured from (-) of cap to neutral.
Then 'friend' writes "It looks like an open grnd. ref" which is a statement rather than a question.
Thanks, Jeff.

There's an excellent site about the whole Neptune control board fiasco at:
Good Luck!
Quick test....check for 110-120 volts AC comming into the motor control board ( bottom right of the washer )...power there = the controls ( machine board, timer, switchs ) are telling the motor to go but the problem is in the motor/motor board. No power there and the problem is likely in the machine board, timer, switchs.

Gave 'friend' your comments this morning and we'll see what happens. If I get a chance I'll get back and report on any progress. Again, thanks to you and everyone else who tried to help us.

The wax motor, door lock and spin enable are working fine, but the machine will not spin. Any ideas? Ron

Over the years I have had ZERO luck getting the schematcs for any appliance control boards. Simpler ones like basic furnaces you can usually just tra ce out. But more complex ones are just too difficult to do that with. Oft en the problem is a bad solder joint so you can look for those. Particular ly around relays. You can also usually test relays without the schematic.
My front loading whirlpool won't stop filling and start washing. Pressure switch is good. If I bang on the control board it will start working. $12
0 for the stupid board. But I'll probably end up buying one as taking the dryer off the top to mess with it is a pain if you have to do it very many times.Good luck.
Yeah, you need to work faster. It's been 8 years.....
What do you expect from Moaners Hub?
