Working on a mah4000aww neptune front loader ,,just tumbles drains water and contnues to tumbles and goes off no spin can u help thnks mm
Hello there, to start the fact that the motor tumbles but does not spin does not necessarily means it works fully. This machine has a variable speed motor that can be defective only on one function. In any case that is rather unlikely.
The most common is either a faulty motor control unit, or a lose contact on the wiring harness.
wiring harness can be tested using a multimeter ,
motor control unit is a board sealed inside the appliance, and must be tested thoroughly.
Even if it is unlikely also a problem on main control board can cause motor malfunction of this kind.
Also ensure the drum is running freely, not oscillating or stiff, otherwise you may also have drum bearing problems.
Here you have the parts to inspect , with diagrams to locate them, and price:
Motor control unit: CONTROL ASSY., MOTOR
Wiring: WIRE HARNESS, MOTOR CONTROL
Motor: MOTOR, VARIABLE SPEED
Main control board: Control Board (CNTRL-ELEC)

Take the back panel off,see if the belt has broke if not,check your motor control board for burn spots ,front bottom right inside washer,if not that then your motor has gotten weak and will not turn the drum,let me knoe what you find-mike

Sounds like you have a door latch problem. somtimes the latch lock wax motor can fail and not allow the unit to think the door is locked.
does your "locked" light turn on???
also how old is your unit?

by the way, are you sure it is tumbling or does it just drain the water with no tub movement?
if you have no tub movement, then you may have a bad motor.
it will require a new motor and control board, and there is a replacement kit available from maytag, but it is about 300 bucks. i would call maytag if you dont have tub movement and ask if they will help with the cost of parts.
im still going to say that your motor has failed. this model has a problem with the motor and if your serial numbers first 2 digits are less then an 88 then it would need motor conversion kit #12002039. i found them online for about 190 bucks.
i feel safe to tell you that this new motor and control board kit will fix your problem.
