Matt for Model Number NX58M5600SW/AA-00 I have the indicated model of a Samsung range where the burders work but I get no response to either bake or broil. The display has a "d" next to the time. Everything I have read suggests I need to replace the motherboard and that the correct part is DE92-02588J. The part you show looks very similar, except the connector on the left side on your part, which I think comes from the display,is a tape-style connector. The one in my oven does not have a tape connector and instead connects at 2 points on the motherboard with push connectors. I can send a picture if that would help.
Answer Hello Matt, we checked the manufacturer's site and using the model number you supplied they list the main control board is listed as DE92-02588J DE92-02588J. If this part does not seem correct for your model and the model number has been confirmed, suggest you check over the original control board and see if there is a label/sticker with a similar but different part number.
