Maytag Neptune washer model# MAH4000AWW – starts and stops:
This unit has a timer and a motor control board and a push start button. When you place the timer on any load size and press the start button, the washer begins and fills with water. Once filed the unit shuts off. It does not advance, the timer is not ticking like any egg timer or moving through the cycle at all. If you press the on/off button again it will fill with a little water but stops and turns off.
The motor control board and the time are both expensive. Too expensive to replace both, but i am having trouble separating out which one it may be. I am not looking to the motor because the timer is not advancing at all or should it be, I am not sure.

Did you check for the tech sheet in the control panel? There is a procedure to test the motor and motor control. I don’t have access to the document.
I would first suspect the motor control board as your problem and run the motor test.
I believe you pull the white plug off the motor control board, set the timer to delay, push start button and motor should turn. 120 VAC across black and white wires to motor control board from timer.

Issue Washer stops in mid-cycle and/or flashes a code.
Action The motor drive system experienced a momentary loss of neutral feed from the power cord to the
Motor Control Board. The neutral line for the Motor Control Board passes across the water valve
solenoids. Neutral to the motor drive system can be momentarily lost If there is poor crimping of any
of the wire terminals in this circuit. This situation could result in a misdiagnosis and unnecessary
replacement of the Motor or Motor Controller Board.
Current Neptune front load washers will indicate a false locked rotor signal to the Machine Control
Board. Washers with a LED display will flash code “LR” in the display. LCD washers will display
“Locked Rotor.” The earlier built front loaders will not display a code, but simply shut down in midcycle
or will not start.
Pull each terminal of the white wire harness connected to each water valve solenoid and verify the
wire is properly stripped and crimped to the metal terminal connector of the wire harness. Make sure
the wires fit snug on the terminals of the water valve solenoids.
A product improvement has been made to the following models. The neutral wire is routed across
the pump only, and now by passes the water valve solenoids.
