Product review (5 stars): Order the fan (DA31-00010C) also or you might have more headaches
This is an exact replacement for the original, however don't do as I did and assume I would take the old fan blades off and put it on the new fan motor assembly.  The original fan has a greenish glue on it, thus the old fan dons't just slid off.  I ended up breaking some of the plastic off of the fan blades trying to get it off.  I had to order and wait for the delivery of the new fan blades.  Luckily I was able to use the old fan/assembly until the parts arrived.  The part number for the fan blade is: DA31-00010C.
