I have a subzero 810RFD undercabinet freezer fridge combo in my home bar. The 10 blade 4" aluminum fan lost a few blades. The subzero part number is 3-15-014-0 which I have searched and searched and can not find anywhere. I was also going to replace the fan motor as the shaft has a slight wobble to it (likely contributed to the fan blade breaking off. The part number of the fan in the drawings are 4-20-016-0. But my fan motor that I pulled out has part 3-15-025-0. That fan motor part (the one I pulled out) does have a cross reference to Dayton 4M249D. But I still need to find a fan blade. The fan motor shaft is 1/8" and I cannot find any 10 blade 4" aluminum fans with an 1/8" bore. However, another model shows a plastic 4" 5 blade fan blade with 1/8" bore PN 3-15-021-0 with now replacement 7014696. I can not find any CFM specs on any of these blades to make sure they will work. If anyone can help I would greatly appreciate it - my beer isn't getting cold!
