Purchased Samsung NX58h5600SS (CR recommended highly) from Lowe's November 2014. Not heavy users of oven, but we followed instructions closely and as per manual tried self-cleaning function in January 2015.
This caused a streak inside oven door window and cracks / discoloration on bottom interior oven panel. Manufacturer-authorized technician replaced panel, took door apart, cleaned window. Self-clean in April 2015 resulted in >multiple< dark brown streaks inside door window, making it difficult to observe items being baked. Technician said Samsung considered defect "cosmetic", wouldn't authorize door replacement.
Contacted Lowe's, they expressed supreme indifference, offered no help, gave us no contact information for Samsung, then rudely blew us off.
Reviewer is in unhappy mood. BuzzDixon stated that there is a room for improvement of customer service and rudeness. Please immediately contact the author of this review to discuss poor customer service of lowes replacement and associated monetary loss in the amount of $250. Lowes needs to offer any options to resolve the issue according to poster's claims.
