I have had the same problem. I have had numerous technicians come out to check the oven tempertures but didn't seem to think there was a problem. I have had mine for two years and can't bake anything decent using convection bake or regular bake. My first turkey using convection roast was still raw in the center after cooking it for the amount of time it should have been done. The temperture obviously isn't maintaining the correct heat. My cake the other day took a half hour longer than it should have. It takes the oven forever to preheat having to use thermometers purchased because when it says it is preheated it never is hot enough. It has taken as long as 40 minutes to preheat the large oven! The customer service dept. are no help as they put you on hold and keep coming back thanking you for holding. They get confused and say they have a ticket for your repair but didn't happen. I am so frustrated with this Chef Collection range, I could scream. We purchased all four kitchen appliances and the only ones I am satisfied with are the refrigerator and the microwave. I am to the point that I am going to scrap this piece of junk and purchase a better model and never buy another Samsung product!
