Product review (4 stars): Excellent Seller! Happy to have conv. oven back! Read more for directions & tips....
Long review but I wanted to include directions on how to change the motor and a few other tips to help so you won't have to scour the internet like I did. I included that below as well as issues we ran into! I hope the long review helps!  We have a Samsung convection oven that began making a terrible noise. We figured out that the fan motor went out so we disconnected it so we could still use the oven and fortunately found one here on Amazon for a good price (this seller). It did take a little while for shipping, it wasn't Prime / 2 days, but I knew that when I ordered it. As I said, until then we just unplugged the motor so that it stopped making that horrible noise and used it on the regular oven cooking mode so we could still bake. Took forever to cook but that's what you gotta do!

First I will cover why I deducted a star as it relates to this: I took off one star because it doesn't come with the retaining nut that attaches the motor to the fly wheel / fan on the inside of the oven and the one that you have now may be unusable (ours broke off inside the nut which is common for this issue). We found that other sellers (not all though) sell it with the nut so that's why I took the star off as we had to find another one. You may get lucky and not need the nut, yours may not break off as ours did and if so this is going to be fine and if not you can find it on Amazon or Sears and order it. You cannot find it in a hardware store so don't waste your time looking. We went to several hardware stores looking for one that would fit (a fastener / nut that attaches at the end of that spindle to hold the fan on) and they said it's proprietary and there was no fastener we could find to fit on it. The size was oddball, we thought it was about a 4.5 mm nut as a 4mm nut wouldn't fit nor would a 5mm, it was definitely between that and wouldn't match anything we tried.

How the seller handled this issue: The seller was excellent in helping us. I contacted them and they replied within a few hours. We had to find a nut and order it for $7 and for our inconvenience the seller refunded all of our money. We were surprised and very grateful. We are now still waiting on the nut to arrive from a different company but after we finally get that all should go well. Although we had no brass nut in our box I still highly recommend purchasing the convection motor from this seller since you may not have this issue at all and if you do they will be helpful in resolving it even though the purchase wasn't a Prime purchase.

If you need the nut you can call Sears and tell them your stove's model number (which is usually on a tag on the side of the warming drawer). On here too you can enter the model number at top of the screen if on desktop computer so you can make sure this is the right part. Once Sears gives you the part number you can find it on here or order it through them. I found it on here for $6. I will add an image of what it looks like (not the same nut but it's similar). It's where the spindle or axle part attaches to the fan, the brass nut then holds the fan on.

Lastly, here's some directions on replacing this motor: Pull stove out. Unplug stove. Remove the back panel from stove. Remove door to get into stove easier (push clips in using a flat head screwdriver and it pulls out). Remove convection fan cover inside if it has a cover. Remove fan brass retaining nut that's holding the fan on to the axle using 9mm socket. Hold fan still by grasping blade with one hand and turn wrench clockwise to remove the nut / fan. TIP: Ours was broken inside and just kept spinning when trying to remove it, if yours is too you may have to do this: Have someone hold a flathead screwdriver on back of stove holding motor still to help stop the fan axle from spinning so the person on the inside of the stove can get the retaining nut off. Once the fan is off......Next:  Unplug fan motor from back of stove. Remove motor (few screws). Place on new motor, reconnect wiring, screw into place. Place fan blade on motor inside stove on motor axle with retaining nut. Reinstall cover / housing. Put stove backing back on. Plug in and test it.

Thanks again to the seller for great service and I hope our review helps you get your oven back and working like it used to, or better! If you're like me you're glad to have your oven back. I was so tired of waiting 45 minutes for a pizza, so glad mine is finally working again. How did we ever survive without a convection oven before? haha
