Product review (4 stars): Product number incorrect as described, it is actually DA29-00020B-1
Very pricey, but fit my Samsung RF23J9011SR perfectly.  I was worried because this product number described as DA29-00020B and the one I removed was DA29-00020B-1, however when the product arrived it had DA29-00020B-1 printed on it and was a perfect fit for me frig.
