Oh great Masters. Young grasshopper needs your beautifoo knowledge. Bought used appliance 3 years ago. Was very great deal. Not so great now as washer no longer spins.
Veeerrryyy frustrating.
Did not know Maytag made weapons of mass destruction. Model number is MHS2000AWW. Serial number is A1822319AV
Have limited knowledge in the great arts. Can take things apart and put them back together. Pulled apart machine and have newer style motor control board. Part number 6 2726410. Where can I pick up cheap replacement if this is the cause? Can't find on Ebay unless under different part number?
Live in Vancouver - Canada.

| If your motor runs, the motor board is probably not the problem. What we need to know to narrow the search down is what does it do in the spin cycle. Does it turn slowly in one direction? Or does it continue it's back and forth tumble pattern like it is in the wash section.

So I finally had a chance to hook it up and watch it. It does everything it suppose to do...door locked...light on...agitates one way...stops...then the other way (i think by the sounds of it)...rinses 3 cycles...just when it gets to the "spin" cycle it skips it completely (the timer knobs jumps to off by the looks of it) and the clothes are still wet. Any ideas?

| If the motor was not moving at all in the spin cycle the upper board is supposed to shut the unit down. Perhaps you just could not hear the motor because the pump was running. You might want to take the front panel off the unit (leave the door on) and run it to get a look see. Start the unit in the number 3 rinse and slowly advance the timer till you hear the drain pump kick on. You can see the motor and belt on the left rear side. If it is just tumbling back and forth, this is an indication of the board not seeing the door lock input or it is ignoring it. IF it is spinning slowly in one direction, this is an indication of an Out of Balance circuit issue. If you can not hear the unit running or see it, after the water is out of the tub pull the wires off the drain pump, this will make it easier to tell what the unit is doing. The spin cycle is about 5-7 minutes or so. If the timer rapid advances (gets to off 30-45 seconds after the pump comes on) you will have to access your upper board and look for burn marks.

I'll try and look at it tomorrow or Friday after work. I'm pretty sure its the upper board as the timer just jumped quickly after a slight pause while I was watching it. You can see very slight burn marks on the board in the picture below. R43 I believe.
I've had a repair company look at the machine before and they swapped a working board in there and it didn't change anything though....unless the wax motor had fried that one too?? They told me I'd be looking at $400+ to start troubleshooting it and I said no as I couldn't afford it. I did buy the wax motor/resistor kit on Ebay and have already changed the wax motor...but didn't want to do the soldering part on the board unless I have to as I don't have any experience doing that and didn't want to wreck it.

So my lazy ass finally got around to checking out the washer stacker. It tumbles back and forth when the pump comes on. The door lock light is on. If seems like its trying to get enough steam to try and start spinning but never does and slowly comes to a stop and then does the same thing the other way never going into a full spin. What could it be?

It's unclear from your reply if you followed Master TTH's advice and remove the front panel to visually monitor the drum movement since audible monitoring may be unreliable due to competing noise from the pump. Please re-read his reply and respond accordingly.

Sorry.
Followed his instructions. Pulled the front panel off. Left the door on. Started at number 3 cycle. The door light came on and said locked. Pump kicked on. The unit would start to spin in one direction but would never get enough steam to start really spinning like its suppose to and then slowly come to a stop. Then it would reverse in the other direction. It would do this several times in each direction until the end where the clothes would be soaked still cause it never really went into a full spin. I believe he said...
If it is just tumbling back and forth, this is an indication of the board not seeing the door lock input or it is ignoring it.
^Is that most likely the problem?

| The out of balance (OOB) circuit has been a problem on these washers and your symptoms seem to point there. Verify by ohming out the OOB circuit. Can do this from the appropriate wiring harness on the machine control. See the wiring diagram in the tech sheet inside the control panel.

I'm bad with electrical stuff. Always worried about frying myself. So assuming I did it right I pulled the electrical plug so i wouldn't fry - machine off. I got 24.1 checking the oob circuit (Orange 40 to P5 Neutral). I also checked the door lock switch on the machine control board (Yellow 36 to P5 Neutral) which gave me 23.4.
Thats all good right?

Motor Phase Test
It is possible for the Motor to still run, under light loads, when one of the phases of the motor is nonfunctional.
A symptom would be the Motor being noisier, possibly creating a growling noise.
Also, because it is out of phase, the Motor torque is less.
This could re-sult in a customer complaint that the load is not spinning out properly or it does not tumble consistently with with a large load
There's (3) windings in the Motor
Each wire pair should show 2-3 ohms resistance.
If that passes, there are some more tests.

Unplugged machine. Opened bottom panel. I pulled the phase wire off the motor control board and pulled it off the motor. I then hooked up the multimeter into each opposite end of the wiring harness. Assuming I did the phase test correctly I was getting 0.9 ohms for each wire. I think there was 5 wires all together. All had the same reading.
Bad right?

Are you using a digital multimeter ?
Does it read 0.0 when you touch the probes together ?
If you're using an analog meter, did you adjust the little wheel to read 0 when the probes are touched together ?
here's the MHW2000AWW Service Manual
Motor Test start on PDF page 40

Digital multimeter.
If I touch probes most settings zero but lowest setting 0.4
Looking at the manual in full I don't think I did the test right. Will redo and report.
