Sensei,

    I seek your wisdom and knowledge.  The machine spawed by devilry, known as MAH5500BWW will not execute its required function.  When this occurred previously, the devil's disciple visited and installed new devilry into the dark recesses, including motor and controller and control board.  Thus, no parts match any picutres or descriptions on this site.

    Seeking to deplete my meager wealth this infernal device once again refuses to spin, and provides "lr," "locked rotor" error on LEDs.  All internal wire connections have been checked and are secure.  There are no obviously burnt compnents.  The door locks and the door locked light comes on.  When devil device is coerced into "service mode" and "spin test" is engaged the basket rotates slowly and intermittently, but does not ever spin.

    Your wisdom is appreciated before the devilry is given as an offering to the god of the dump.

Domo arigato.

Not sure how this can be true... unless non-OEM parts were used in the repair. Do you know whether or not genuine Maytag parts were used?

Do you have a serial number of the unit?

Master, 

Devil's desciple was dispatched directly from underworld and came wearing the mark of the devil on his chest.  The serial # of infernal device is S71787623ZK.

Magical rendering of offending devices is attached...

When "devil's diciple" replaced parts, was one the motor conversion kit Maytag part 12002039? If not, this is what you're looking for.

Yes, conversion kit was installed. Thus, my motor control board seems to be different from those shown on the site.  And I do not know where to start troubleshooting.

Pun into "quick spin" in service mode. What happens? If nothing ck for 120vac between white and black at lower board. Also, ck at red and blue. Do yourself a favor and inspect the plug on the motor for broken/bent plug or terminals. If power to motor control and no motor movement new board is part# 22004046. I have never seen it (and not sure if I believe it) but, some have said a loose neutral at the water valve could cause a LR code.

When I go into quick spin the door locks and the pump comes on.  After a few seconds (15?), the drum rotates slowly 3/4 of a turn and then stops.  It creeps forward another inch then stops.  Then the rotation sequence starts again.  It never seems to end.

I have 120vac (+/-) at black/white, and red/blue at the board and on both sides of the (filter capacitor?) little grey thing.  I have re-seated all the connections at the water valve, both pc boards, and at the motor itself.  I can't see the back side of the connector on the motor without pulling it.

Any further ideas?

From the front remove the 5/16" screw with strain relief at the motor harness (the one attached to the motor) to remove the harness from motor to inspect. While this is out you can ohm the windings although I have yet to see this particular motor bad. If all checks good in all likelyhood you're looking at another motor control. If not installed too long ago, Devil's Disciple should have a guarantee on part.

I will do that now.  It's been at least a year since the conversion kit was installed (major smokage of prior board).  It seems that the conversion kit and the board alone are both the same price.  Should I just order another conversion kit and change the motor, too?

I pulled the strain releif and all the wires appear properly seated in the back side of the connnector.  The color coding in my machine does not seem to match the schematic supplied inside the machine.  What resistance should I see across the windings?  Is the pattern still outside pair, next pair, inner pair?  (One wire is green, which I would expect to be a ground???

Pattern should be the same, look for resistance close to the same reading on each winding. I'd be lying if I told you I could remember the resistance. Like I said before, I have yet to see this motor bad. I have however seen a couple (not many mind you) of the new boards fail. I'd be confident with the board alone to rectify the LR code. Good luck!

Ohming out this motor is a little different. The old motor you could ohm individual windings, this one you must do two at a time so the resistance will be double. Ignoring the Green and I believe the two gray wires right next to each other, any combination of the remaining 3 should have approximately 6-7 ohms. Since they never published a schematic off the kit installed, I can guess off the wires on the new series above and go with Brown, White & Black. From Gray to Gray you should read 150-200 ohms.

Thanks!  That was the ticket...  I get 176Ω grey to grey, and 7Ω between brown, white, and black.  Is it certain I have a bad motor controller board?  I'd hate to spend $200+ and find out that it wasn't fixed.  Thanks again!

Great troubleshooting thread! :dude: Wish we could get pictures to go with the clear, detailed explanations from Masters Stumpowitz and TTH.

Here's the part link for the revised board: http://www.repairclinic.com/referral.asp?R=154&N=1001059

Sensei,

This part is on backorder, but they do have the conversion kit: http://www.repairclinic.com/referral.asp?R=154&N=949491.  Is there any reason not to but the whole kit?  (The price is exactly the same).

I have taken photos, and will add as replies to this thread.  Many thanks for your help -- beer fund donation next...

Here is a picture of the innards of the Maytag Neptune, with the front panel removed.  The motor is on the left, and the control board (and plastic case) on right.  The plastic cover has been taken off the control board.

Here is a closeup of the motor.  There is a long 5/16" bolt that holds the connector to the motor, with a nut on the back of the motor.  Taking out the bolt will aloow you to check the connections on the back of the plug.

Here is the motor control board (after the conversion kit has been installed).  Check the blue/red and black/white (upper right) for 120v.
