What is the correct replacement kit for my N821, ser # 8479410. Norcold gave me #632168001, which kit do I need?

My unit is giving me a F code. It won't happen at lower elevations, and didn't use to happen at 7000' but now it does. I start the refrigerator and it will run until it gets cold but when it calls to re-ignite it goes into a fault (F). Works fine at lower elevations and on AC. Was going to replace my gas bottle regulators first then the control unit. What else can I look for.

Thanks

With serial 8479410, your N821 is below 9126825. The 632168001 is the power board alone, and the 637779 kit replaces both boards. Both are discontinued now. The altitude clue helps: at 7,000 feet the flame is weaker, so any buildup on the burner, orifice, flue or electrode shows up there first. Clean the orifice (with alcohol), burner and flue, and check the electrode position. Checking your regulator is a good idea too.
