Brian M Kensington , MD February 06, 2016 Appliance: Samsung Electric Range NE58F9500SS/AA-0000 Samsung convection oven display and counter top rings worked ok but no oven functions no error codes displayed Replaced control board for presumed oven element relay failure ( the relays are not user replaceable- you have to replace the whole board) Repair took ten minutes- could not be easier. The oven functions were restored. The Samsung convention oven slide in range is a total disaster for reliability. It has broken 4 times in only two years of use. Its price is quite high (1300.00) but it is a TURKEY. Even the Extended Warranty company refused to repair this oven I would urge you not to buy one in the first place, but if you made the mistake I did and buy one-you can fix it when needed. The Part arrived within two days with regular shipping and was easy to replace with just a Philips screwdriver.
