Apologies if this is the wrong group!

I'm wondering if anyone could help me troubleshoot my Maytag Neptune
washer:

It is a Maytag Neptune MAH7500AWW (LCD control panel). Note that it
DOES NOT use the wax motor on the door lock - our model uses a
solenoid. Also, our machine has already had the motor/motor control
board upgrade.

We had the spinner seal failure with ruined bearings and I replaced
the bearings and seal. It ran fine for about a week, then started
leaving wet clothes at end of cycle with a notice on the LCD that the
machine did not spin. It seems to be detecting (what I believe is a
false) out of balance condition and repeatedly trying to redistribute
the clothes. It does this with no clothes in the machine.

I've tested all of the external out-of-balance (OOB) switches for
proper operation and connections. I also tested with a wire shunt,
taking the switches out of the circuit, to make sure the problem
wasn't any of these switches. I happen to have an extra motor control
board so I swapped that in...did not fix the problem.

I read that the control board monitors feedback from the motor as an
additional check for an OOB condition. If I run a cycle or the quick
spin test in service mode and watch the drive monitor numbers (RPM,
Torque, Unbalance) I see that the Unbalance number hovers around 20 or
30 from 0 to about 90 RPM. Above that, the Unbalance number suddenly
kicks up to around 140/150 and the motor shudders, but still
accelerates. At about 400 RPM the Unbalance number drops back down
and stays there all the way up to 1000 RPM. I took the motor out and
reran the test - it runs smoothly until around 100 RPM then jerks and
shudders until around 400.

Since I've replaced the motor control board, I'm thinking there are
only two other possibilities: the main control board or the motor
itself. I've checked for continuity at the motor terminals - there
are three connections going to the windings, with good continuity
among them, two leading to the tach windings, likewise good, and one
ground to motor chassis. The shaft spins freely with no binding.

I've read that a defective winding could cause motor jerking, but why
would it only happen during certain RPM's, and wouldn't I be able to
see an open with my ohmmeter?

Could the problem be in the main control board, or do I need a new
motor?

Thanks!

Reairclinic.com has a good return parts policy. Tall it over with
them, order both and send back what you don't need.

That washer was way too expensive. And IT is the problem. Go get your
wife the cheap one - for example one recommended by a dude few posts
after yours She will have more fun and you will save some
dollar...

I have had the same problem...replaced bearings...appeared to have
them snugged too tight causing the motor not to spin properly. Hope
you figured yours out.
