Product review (5 stars): Timer works!
The Whirlpool 3976576 Timer arrived quickly and undamaged.  Installation took a bit longer than expected because there were no instructions and access to the panel was from the front.

The timer has worked well now for a  month and I'm satisfied with the purchase.
