Worst product & service for a Premium Chef series Samsung induction stove S/N 0BSG7DDFB00054J M/C NE58H9970WS/AC Case # 5126540166 # 5126579451 Contacted Samsung for service on November 12 since the cooktop was not functioning. Was given ARS as authorized service center. During first visit on November 16, fuse was replaced but problem was not being solved, was told by technical person to replace the relay board the next day. Waited for 2 weeks, relay board was replaced and again problem was still not rectified. Asked the technician to contact Samsung for advice, was told to replace filter board. After a long long wait, finally the third service came on December 29, unfortunately my lovely premium Samsung Chef series induction has no response. Contacted Samsung professional technical department, advice to replace another 3 boards (what's new?! Draining consumer's wallet?) I called Samsung to escalate the issue after $$$ spent & meaningless long wait, was given a case # by "Executive Customer Relation department", Dwayne G. Was told he will contact the service center & promised to get back to me in 2 to 3 days. Trying to be reasonable for the holidays, sent an email on January 3, no reply; another email first thing in the morning on January 5. Waited for few hours & called Samsung. Got a ticket #, talked to another Executive Customer Relation personnel, Brian, all I heard was meaningless apology again. Obviously I received reply from Dwayne shortly. After such painful battle with serving princess Samsung Chef series induction stove, I would like to reach out to everyone in my capabilities in all forms including forums, complain boards, social media platforms & personal & real estate agent contacts, as well in different languages, letting consumer to know how inferior Samsung is, and to prepare having a deep pocket for any services, don't consider purchasing extended warranty as it only covers minimal parts. Go cheap, don't imagine a premium price will bring you a premium product & service.
