Product review (3 stars): Works but does not appear to be an OEM part.
This part fits but the frame is not straight, one side is a little too long so it's more like a polygon than a square.  It's also not an OEM part because the OEM part did not have a grill on the backside.  This part has grills on both sides and glue is smeared around the charcoal filter on one side.  There was no glue on the OEM part that came out of the microwave.  The metal frame seems to be the same material as the original, just not cut square.  It works, just not sure about it being an OEM as advertised.
