Maytag MAH4000AWW no longer does the high speed spin cycle. Other than that motor runs fine. Seems like a controller issue but don't have a repair manual to know for sure.

I don't know these front loaders so well but, here's a couple of things to look for.
1) If belt driven, look for the spring loaded tensioner. Once tension is released, check the pully & see if it has excessive play.
2) Check the gasket on front panel & see if drum has rubbed thru it in order to make metal to metal contact.
3) There is alot of pressure on that rear bearing...make sure it's not egg shaped or scored on the inside.

If all else fails, shotgun it (in other words, replace those moving parts you suspect:)

Hello K.W. ,
Sad to sad their is no way to reset the control and yes it sounds as if has diagnosed it spot on ...since it spins on the rinse cycle the motor can be ruled out totally as the problem since its up to the control to tell the motor what to do and when to do it so if it spins sometimes and not others it seems to be the control that's not telling it to spin at the end. One thing to check though is that the filter screen perhaps is clogged since i believe it doesn't spin at high speed until after the water has drained and if the filter on the pump is built up w/debris its not going to drain fast enough so while it may not solve it,it may solve it by checking the drain filter. This tip i wrote will show ya how to check the filter on the pump.http://www1.fixya.com/support/r10121384-check_when_duet_washer_door_locked_after

If the filter is relativity clean and doesn't solve the problem the control baord would need to be replaced.

Your problem requires very skilled LG technician to check the wiring circuit from the control board to the motor and hall sensor. Very possible that the control board is bad but highly unlikely. Suspect the wiring harness with high resistance to the motor.
Good luck

the motor control is bad

Make certain that your selected wash cycle designates a higher spin speed. If so, then you may have an issue with the motor or motor control board. Contact an appliance service company.

two problems here,
your shaft seal is running on its last leg
the sound is unmistakeable and always described the same...
the water issue, you probably have a trickle leak through the cold water valve
the mixing valve is quite an easy repair, but I would have to say with all honesty, it probably time for a new machine
the hub seal is a tub replacment call
2 hrs of labor if hes good
and the tub runs around 500.00 dollars
sory for the bad news

I found this on line ... 6/15/09 . Does your Maytag Neptune front loader sound like a runaway freight train when it is in high speed spin cycle? 2. Is your Neptune getting so loud that you cannot be in the same room while it is spinning your clothes? It sounds like your bearings may need some attention if you answered YES to the questions See www.neptunebearing.com ... Frank [email protected]

TIMER SWITCH NOT WORKING PROPERLY

my front load washer is leaving water after done spin cycle can still ring water out of clothing....water is draining from hose and is spinning somewhat strange...like its not going through rinse properly sorta like its repeatedly doing same cycle pattern...spins for lil, stops makes running noses...spins sum more....soapy clothing...its 5 years old..but first time use this month finally connected it...when took bottom off to check hose connection noticed control board looked lil warped and brownish colored but not as meant to be..maybe its burnt out?
