I had a customer complain her Maytag Neptune washer would cut out during high speed spin. I checked the basket for rough bearings, but couldn't tell. Apparently, the bearings hadn't reached the level of failure that causes a roar.
I put an amp probe on the main black input power wire to the motor control board and measured about 1 amp at low speed and over three amps near maximum speed and the motor started to overheat. This confirmed to me that the bearings where bad.
Later,I picked up the washer as junk, took it apart and confirmed bad tub bearings, so apparently my check was valid. Any comments, please.

The bearings don’t necessarily need to be totally shot
in order to cause a problem like this. They might work
freely when removed, but when you put belt tension on the
pulley or a load in the drum then they can bind enough
to place an excess load on the motor. Given more time this
would have either fried the motor or even more likely the
motor board.

Thanks for the info Glen65, I have little experience with these washers, will help in the future.
