Product review (4 stars): It's a fan; what headline could be written?
The information I had read online said that all Frigidaire evaporator fans were the same.  That information was woefully incorrect.  However, it's not the seller's fault, it's the fault of that guy who wrote that original article I read.  I am hunting him down now.

This fan did not fit my refrigerator, but it did work.  I brought it to a local appliance shop to see if there was a 3 to 4 pin converter or something I could find, and they ran a test on it for me.
