Kitchen Aid washer made by Whirlpool, model KAWS700G. A couple months ago, the rubber and plastic coupling between the motor and transmission broke. That was a fairly easy fix. New problem this time. Last week I was doing a load of towels and while I was standing there the timer quit turning and made a loud humming sound. I took the timer out and sprayed it out with contact cleaner but that didn't help. I went to the local parts store and bought a new genuine Whirlpool replacement timer. I installed the timer it hummed loudly like the other one but the knob moved around for a couple minutes and then it stopped and the hum went away. I turned the knob around to spin again (spin so the machine wouldn't fill with water). Nothing. No hum. No movement. Before I make the trek back to the parts store, is it likely that I got a bad replacement timer? Any other likely points of failure? I do have a DMM and nearly very complete tool chest. Thanks.
