Product review (5 stars): Fits and works well.
Used this to replace an Active Defrost Controller in a Maytag (made by Whirlpool) refrigerator.  The ADC board gave me nothing. but. trouble. on this refrigerator, and I finally gave up and replaced it with this.

Smartest decision I've made with this piece of crap refrigerator yet.  The timer fit EXACTLY into the same spot as the ADC board, (the fridge even has a hole for adjusting the timer so it was obviously designed to take it) and 10 minutes with crimpers removed the ADC plug and replaced them with spade connectors that fit directly on this timer.

You can figure out how to wire it in from Google; It costs a TENTH the price of the ADC board; it has turned out to be MORE reliable than the ADC board.  Score.
