Purchased this item after our norcold n621was acting up. Only auto button would show, and all other controls seemed frozen, and fridge was not working in either mode. Purchased a dinosaur board from another business and did not fix problems. Found this kit, followed installation instructions and within ten minutes our fridge was working flawlessly again. Thanks norcold guy! Take their advice and replace both boards at same time...

Found power going to the unit however would not turn on. Paid the 40.00 and Brian e-mailed me and figured out needed new board with the front adaptor on front of refer. Very easy directions to follow. Make sure you label your wires that you remove from the old board. Connect everything and it works flawlessly. RV place wanted 95 clams an hour to diagnose and replace so was looking at a 500 $ bill at least

ordered part for model N821 refrigerator which I received in 3 days and installed it using the instructions included. Had a little trouble as the instructions cover many different models but was able to get it installed and now the refrigerator works like new. You need to read the instructions a couple of times and it would help to label the wires as you remove them as to what they are.Then when you put them on the new board you know which wire they are talking about

purchased a optical and power board for my N821 Model Refrigerator works like a champ will do more Business with them...installation was easy just make sure and read all instructions and it should all go well...thanks Brian...
