Product review (5 stars): Nice and quiet
I needed to replace my old fan as it had gotten very noisy.  Oven was 12 years old.  This one appeared to be a perfect match for the original.  Hardest part was pulling the oven out from the cabinet enclosure and stabilizing it to work on.  Then just had to remove a bunch of sheet metal screws on the back panels to get at the fan (in the upper back).  New fan is SO quiet.  Wish I had done this a couple years ago!
