Dark display or buttons that don’t respond? Norcold has discontinued every N8XX optical (display) board, so if that board has truly failed, a new refrigerator is the fix. Before you decide, run the checks in our optical board guide. A dark display is often a power or fuse problem, not the board. If you do need a new fridge, the Norcold N8XF keeps propane and electric, or go 12V compressor with the Norcold N8DC. Send us your model and we’ll confirm the fit for your opening.
