The timer is still available.
I work for an appliance parts store. I can still get that timer from Whirlpool (they bought Maytag in 2006). Call my store (513) 221-1195 between 8-5 weekdays and ask for Dave if you'd like to order one and have it shipped to you. It would be $118.59 plus tax and shipping.
You could probably find one online cheaper, but this option is what I can offer.
