Yes. The Norcold Optical Board 641592 / 51023 is the correct board for your N8DCSSR. It fits the N8DC, N8DCSS, N10DC and N10DCSS with serial numbers above SE079WDW00190, and your serial (SE301YDW00230400) was built after that cutoff. N8DC units below the cutoff need the Norcold 640338 instead. The "R" at the end of your model number doesn't affect fit.
The 641592 replaces the older 640089 and comes with the 640087 front panel and the ribbon cable, so you're replacing the whole display assembly. It fixes a freezer that cools while the fridge doesn't, intermittent or dead front panel controls, and a fridge that won't turn on or off. Install takes about 30 minutes with a screwdriver. Disconnect 12V power first and take a photo of the connections before unplugging anything.
