Maytag MAV8557AWW wont spin.

So recently the motor locked up on my maytag mav8557aww. I ordered a new motor, and replaced it. .(Old motor was locked, would not spin by hand, even with belt off.)

Now with the new motor, it will only buzz when I try and put it on spin. This model washer doesn't have a start capacitor either.

I checked continuity through the lid switch, and I am getting proper continuity on both circuits.

I also checked continuity and ohms for the wiring harness. I am getting continuity for every wire, but the orange wire (for the speed circuit) is .4 ohms, while the rest are 0.0 ohms. Considering replacing this orange wire.

Only thing else I could see that it could be at fault is the timer. Any idea how to test this timer/multifunction switch without just firing the parts cannon at it again?

To be clear, the motor will not spin, even with the belt off. So it couldn't be related to the water pump, or transmission/stator.

Checkedd terminal 1/6 and also the white to orange for continuity and ohms. Getting good continuity and low ohms reading on both motors.

The old one wasnt burnt up. its got a bad bearing or something. Its frozen, it wont spin at all by hand.


I am thinking it has to be the timer assembly. I wish I had 120v power supply, I am used to dealing with 12v electronics, and I can my bench supply for anything between 0 and ~14 volts.

Hi @roberttanksley

Perhaps the replacement motor is faulty.

Have you still got the old motor?

Check if there's continuity between terminals 1 and 6 on both the old motor (hopefully its not burnt out) and the new motor wiring terminal block.

Terminal 1 (red harness wire) connects to the centrifugal switch in the motor, which connects to the start winding. Terminal 6 (brown harness wire) connects to the other side of the start winding.

At normal the switch is closed, completing the start winding circuit.

When first started, both windings, Start and Run, are energized to create sufficient magnetism to overcome the inertia of the motor when idle, to start rotating the motor.

When the motor has run up to speed, this switch operates to disconnect the start winding allowing the motor to continue operating on the run winding only. The start winding has only thin wires and you don't want them to burn out. The run winding has thicker wires

If the switch is faulty i.e. open circuit at normal, then the start winding is disconnected from the circuit and the motor can't start on the run winding only and you'll hear a humming sound.

The switch is internal to the motor and there's no separate replacement part.

Here's a link that has the wiring diagram that may help

@roberttanksley

Looking at the wiring diagram for power to get to the start winding through the timer contacts, check if there's continuity from timer pin #9 to pin #16 when the motor has to start. The motor needs to be connected when testing or with the power disconnected short out terminals 1 & 6 on the motor and set the timer to the spin position

If not then the timer is faulty and will need to be replaced as there's no internal spares for it.

The timer is part # WP22004380 examples only)

Followed your advice.

No continuity through from 9 to 16 on spin.

I replace timer. I think this brand new motor is fault as it tries to start. Spins slightly, then just hums.

I plugged back in the old motor, and that one seems to try actually start (louder humm, and vibration, but remember its locked up. wont spin by hand at all)

Going to return the motor I bought online and see if I can find a used, known good motor, or another vendor.
