I have a 5 year olf Kenmore elite washer that does not spin/agitate or pump water. Took the shell off, pump off, motor off. I left the motor connected to the wiring, tried to spin/agitate, but get no motion on motor, just a buzzing noise. Seems like the motor is bad? Is there any way to test this, or maybe there is something else I should test. Seems like tranny turns OK, pump turns OK. Thanks!
