Product review (2 stars): Not a true replacement
Bought this for my old fridge in the basement, Whirlpool Model # ET20GK.  Good deal for $12.00. Was supposed to be a replacement for part # PS376645. It isn't.  Came with no instructions! My bracket is 8 inches long.  This one is close to 6 inches.  So you need to fabricate a longer bracket if you have the same one I have.  I was able to rivet the old one onto the new bracket to lengthen it.  The fan w/ this is too big for the hole on my mount in the freezer.  I trimmed that down.  During all this fabricating I broke one of the wire connectors.  The small copper wire went into the sealed housing and I can't get it out.  I'm done playing w/ this for tonight.  Be prepared to do some extra wok to get it to fit.  Shipping was very fast (had it in 3 days).
