bought samsung single oven dual flex in 2019, works for about 2 years but lapse the warranty period. First problem it never stop heating up, pass the set temp and continue until it stops itself (some kind of auto shutoff protection). Called samsung and got a list of certified/authorized service companies. Read the reviews and none has good review so, I called a couple of local technicians, they came out and suspect a problem and said will contact samsung to discus and get the part and, samsung will not sale the part to them. Called samsung and they said they only allowed authorized repair companies to perform repair. This is not acceptable business model, I understand if it is still within the warranty, but in my case, it was no longer covered by it. Since, I have a not working samsung oven to display on my wall. NO MORE sumsung.
