Maytag MAVT446AAW Washing Machine diagnosis help?

[ajf3]

Hello all,

Writing in hopes that someone could help in diagnosing some problems I'm having with my Maytag MAVT446AAW washing machine.

When it tries to agitate it just hums and gives off a burning scent...  I think the motor pulley is spinning on the belt, which isn't moving.

I tried the "unofficial" test of holding my left hand on the drum and putting it to spin.  Without any pressure it does spin, but I can very easily stop it from spinning with my hand.

I installed a new transmission pulley/thrust bearing kit, but that didn't seem to do it.  The hand test, I've read, indicates a clutch replacement is necessary - but I'm unable to locate a clutch part on any of the parts sites - is it built into the transmission on this model?

...or might it be something other than the clutch?

Thanks!

Remove belts n run test again.

 

If it still hums . Might have defective timer.  Part number: 21002232

Brother Ivasquez, that's great you're posting part numbers for people but would you mind using the yellow APP button the editor tool bar? This way it links people directly to the part they need and brings in any associated photos, making for much more helpful post. This 30 second video shows how:

Hi, thanks for the reply!  The motor pulley does turn so I think the timer is working correctly...

Agitate and spin are very different functions. Did you try to spin the drive pulley in the agitate direction?

Check the pump, they can get bound by debris in them. Make sure it spins freely both ways.

Hi!  Thanks for the tips...  I took the belt off, both the motor and pump pulley spin in both directions.  The drive pulley (? the one attached to the drum in the center) turns counterclockwise freely, but then just a bit clockwise before stopping - feel kind of like the clutch is engaging for agitate?

sounds like the transmission is locked up

Is the drive belt glazed n cracked Part number: 21352320

prop front on 2x4's

Pull front cover - let unit fill - watch motor as it goes to agitate - when it fails - carefully assist motor by pulling on belt

No, it's actually a brand new belt - I replaced that first...

Want to make sure  I understand...  with the belt off, unplugged, laying on it's side you're saying the drive pulley should turn freely in both directions?  ...and if it's not, the transmission is likely toast?  Just want to be real clear on that before I give up...

Thanks for all the help!

Not freely. It should spin freely in one direction and then turn with some force in the other direction while starting to spin the tub and then it will stop because you can't provide enough torque to disengage the brake before it catches again. Turn the drive pulley in the agitate direction. If it turns freely you can run the motor in agitate with no belt attached. That's an easy way to see that the motor works but it's not always accurate as an unloaded motor will spin when a loaded motor will not.
