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

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.
Here's what he gave me.
1. Washer does not spin or tumble.
2. 'Door locked' light comes on.
3. +25 at P3-1 measures 120 vac with Dvm (when 'door locked' light on)
to neutral ref. (possibly open ground ref.)
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
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.
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.
Some other stuff that may help.

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.

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
