After the timer quit we had one more load to do so we ran each cycle manually, advancing the timer by hand through the pre-soak, wash, rinse, spin cycles. That told us there were no problems with the other switches. Pulled the back off the control assembly and it was no big deal to get the old timer out. I suggest doing that before you order and comparing the part you are replacing to the images shown online (since there are two timer versions for this model) to make sure you get the right generation part. Ordered Thursday night at midnight, got the part via UPS by Saturday (Denver). Took about 15 minutes to get it back in. Our machine's timer knob was held in with a clip - just popped the white cap off the knob and slid the clip off the shaft. No tools for that part. No big deal. Did the whole job with a phillips screwdriver, a 1/4" socket and a 5/16" socket. Part was a little over $150 with shipping. Ebay had them cheaper but didn't want to risk problems with a used part.
