Easy fix, this was an identical match to the fan that was in the oven. The only thing missing was the foam strip, that easily came off the old fan assembly and stuck to the new one.
The hardest thing was finding the part, and with a picture to verify. I have found appliancepros.com has a large list of available parts,easy to find in their inventory of available items, and some of the best prices as well. This is a Whirlpool convection slide in oven, and the Whirlpool site was worthless, did not even have a listing for this part, or if they did, we could not find it. My wife was looking for it on line on the Whirlpool site while I was working on the oven. She got frustrated and I suggested she go to Appliancepros.com ( I ordered an oven handle years ago, and the name stuck in my mind). She found the part in less than 2 minutes, and had it ordered before I could close up the back of the oven.
