My Samsung oven, model number NX58R5601SS/AA does not turn on. There is a lower case d in front of the time. I discovered that it didn't work about a week after the warranty expired. It had sat disconnected for several months because my kitchen was being remodeled. It was reconnected and never worked again. Totally disappointing that an oven that I barely used is non functional. Customer service was no help, I have no Samsung service anywhere near me, and even if I did, the week out of warranty made it so I'd have to pay for service no matter what. I guess I'll have to pay some service person to come out and probably spend hours trying to figure this out.
