Jenn Air convection fan replacement

The convection fan in my JER8850AAW oven has suddenly stopped working. Interestingly, the little fan icon on the control panel still displays (and rotates) when convection bake is chosen, and there are no error codes displayed. I take this to mean the fan is simply dead. I looked at the parts list to order a replacement, but was momentarily taken aback by the existence of two types of fans:

"Fan asy., Dual convec" Part Number: AP4100416
and
"Fan, convection assembly" Part Number: AP4092659

My oven only has one fan, so I’m inferring that I should purchase AP4092659. Can anyone confirm this?

Thank you.

Update: spoke to Jenn Air yesterday. The point of confusion was caused by the fact that [for my model series 15] the part #AP4092659 has been superseded by part #AP4100416.
