Checked Samsung web site & learned part was discontinued. Went to Lowe's & was given a card to contact Lowe's parts dept. They confirmed the part was discontinued, and had no suggestions for a replacement. Went to AppliancePartsPros.com web site & found a substitute part listed, along with a verification box that allowed me to check that it would be appropriate for the model in question, before making the order. Part arrived sooner than expected, well packed, in order, and was installed immediately. Kudos.
