Hello. I've searched far and wide on this forum (and what a might fine forum it is!) I've learned much and done several hours of troubleshooting and service mode tests.

My conclusion: the motor control board needs to be replaced -- with the Maytag conversion kit to be exact.
As professionals, do you agree ?

model: MAH5500BWW
serial: 71783261ZK
circa: 2001
status: all original parts
(yes...that's right, if this were a car, it'd be a classic, going for twice the original sales price! But alas, it's not, it's only a mere laundry appliance)

Back to my troubleshooting completed to date.
    (1) Jackpot - found the hidden mini-manual in the machine control panel.
    (2) belt appears intact and I can manually spin the drum by rotating the belt while on the motor. Kids...don't try this at home...you will pinch a finger!
    (3) board output tests: all outputs test OK. Motor control relay engaged (120 VAC between motor control board neutral and LI) only when door was locked (via the output test).
    (4) machine control board test: 120 VAC output to the motor control board. This was already confirmed with the above test. Again, I had to force the door locked while in service mode. No spin.
    (5) motor & control control test: removed JP4 (the signals back to the machine control I think.) The manual indicates that it should spin, but no spin.
    (6) continuity on the 10 A fuse on the motor control board
    (7) visual inspection on 6 semiconductors: the rectifiers appear to be in good health. No obvious signs of turmoil on the board.
    (8) windings on motor: powered down the washer and each pair of windings had the appropriate 2-3 ohms resistance. Motor seems OK.
    (9) service mode quick spin test: door was already locked. display remains at 00. The drain pump sounds like it's going but no spin in the drum.
    (10) conclusion: the motor control board is getting the voltage it needs. But it's not returning the favor to the motor.

Any recommendations on what to test/try next? Or just order the dang $225 motor & motor control board conversion kit from RepairClinic ?

The new Drive Motor Conversion Kit has been installed (the kit and shipping was free, courtesy of Maytag's 10-year drive motor warranty on this washer -- no cost to me...woohoo)

Washer is back together and ran through the quick service cycle and it's first load without issues.

Now I have an extra drive motor just sitting in the garage...anyone want it ?

Thank you for the great info on this forum and kudos to Tronicsmasta for confirming that the issue was the motor control board. (I upgraded my membership to help keep the board running.)
