Kenmore HE3T Washer Issues

Hi,

Here is a little back story leading up to the issue at hand. My Kenmore washer (model: 110.44921.300) is a little over 10 years old. We have had zero issues with the washer up until this past month. This past month we had an issue with the drum not spinning at all. After reading the troubleshooting manual on the inside of the washer and coming to this amazing forum, we found out that the MCU was bad. We found this out by the ohms readings off of the wiring harness from the MCU to the Motor. We were seeing low voltage and infinite ohms from pins 1-2, 2-3, and 1-3. After purchasing a new MCU and installing it in, we had zero issues for the first 2-3 days. Now all of a sudden, we are having the issue of a F06 code flashing. This occurs when washing or running drain/spin cycle on the washer. We have double checked all the connectors and contacts are free of oxidation and are secured snug into place. We have double checked the door switch is good and we have also ensured the drain area is free of debris along with the drain line. But one of the things I have now noticed, is that the ohm readings from the MCU to the Motor are 32-35 ohms on pins 1-2, 2-3, 1-3 and the tach ohms readings are 52-55 ohms on pins 4-5. Seeing how we just replaced the MCU and I'm almost positive that the CCU and Motor are good, is it possible that the MCU has failed again? Can you please provide me information on checking the Motor(we would like to double check it) and actually anything else that could be causing this? I'm kinda at a loss and a little bit frustrated at this point.

Thanks,
Sean

The F/06 is:
Drive Motor Tachometer Error
The control is unable to properly detect motor speed and the machine will shut down. If a failure occurs during high-speed spin, the door will be unlocked after 3 minutes.

So if the motor checks fine, then its the MCU thats bad. Since you just replaced it, it would be defective, just contact the place where you bought it at and get an exchange for another new MCU.

To ohm test the motor: Disconnect the wire connector on the motor and measure the motor windings between pins 1-2, 2-3, 1-3. It should measure about 6 ohms,+ or - 5%
