Title: Maytag Ensignia Topload Washer Drive Motor Overheating MAV8557AWW
Post by: rockinrobin on April 04, 2013, 08:05:18 PM
During Spin mode the Drive Motor runs briefly then shuts off, there's a burning smell coming from the Motor and it's very hot to the touch.
All 3 Pulley's turn freely both direction's and the Belt looks fine (no cracks).
The Tub moves when turning the Transmission Pulley CCW and the Agitator moves when turning it CW.
Therefore, should I replace the Drive Motor (P/N 21001950 (http://click.linksynergy.com/fs-bin/click?id=omv7WULuxaw&subid=0&offerid=225193.1&type=10&tmpid=2111&RD_PARM0=http%253A%252F%252Fwww.appliancepartspros.com%252Fwhirlpool-motor-assembly-21001950-ap4024680.html&RD_PARM1=http&RD_PARM2=%253A%252F%252Fwww.appliancepartspros&RD_PARM3=.com%252Fwhirlpool-motor-assembly-21001950-ap4024680.html))? :-\

How long does it run before shutting off?

  Is it actually running (pulley rotating), or just humming? If just humming, try it with the belt off.

The drive motor makes a humming noise with belt on.
The drive motor runs with belt off.

  Check to see that the motor freely pivots on the motor plate. This assures correct belt tension and allows the belt to slip during spin startup. If this is ok then you would need to take some live line voltage measurements at the motor during spin startup to check for voltage drop issues and check the current draw with an amprobe.

I have 2 Question's:
I have a cheater chord with 3-prong plug, can I use it to test the motor with belt attached to see if it runs and spins the tub?
If the Motor runs and Tub spins with cheater chord then would the problem be a bad Timer?

  Yes, that is an effective troubleshooting technique. You will need to connect the hot (black) wire of the cord to where both brown and yellow connect to the motor  and neutral (white) to where both black and red connect to the motor. If it works ok this way, the problem could be the timer, speed switch or a faulty wiring connection point.

  Just to be clear, the connection point wire colors that I gave you are where the normal harness connector connects, not the colors of the motor side wiring. They are different.

Thanks for the info.
FYI: I found this video (link below) on how to test a 2 Speed Maytag Washer Motor using a cheater chord

  That does not have the same motor switch as your model.

If I check AC Voltage and Current Draw on the Wire Harness Motor Connector, is the power first sent to the BK & YL Wire (Start) then power sent to the RD & BR Wire (Run)?

  Power is applied simultaneously and continuously. As soon as the motor comes up to speed, the start circuit is opened via an internal contact in the motor switch activated by a centrifugal mechanism in the motor. This centrifugal mechanism also operates another set of contacts in that switch for slow speed operation. The motor always starts in high speed regardless of user setting but if slow speed has been selected, it will switch to slow speed when the motor gets going.

Eric,

I'll review the Wiring Diagram to help with troubleshooting power going to the motor, speed switch and timer.
I'll update this post when it's repaired.
Thank You!
