Product review (5 stars): Whirpool Double Wall Oven (W10406070 Control Board)
I tried to buy this part 3 times under the Whirlpool Part Number 8302319R (the "R" indicating Refurbished) and each time the seller sent wrong part. It was half the price but I only received the correct part when I ordered using the other known part number (W10406070)...higher cost but still less than local Appliance Parts Store. It works perfectly and Double Wall Oven even operates quieter including after cooking w/the fan cooling.  Pretty easy DIY just pay attention to where the plugs go.
