I figured it out that day luckily! I called Norcold and asked. Surprisingly they were willing to talk to a non-dealer and answered the question within a minute. I can not believe I have spent 10+ hours trying to figure this out and a minute-long phone call gave me the answer. I guess it is just finding the right person that has seen it.
The o code is a bad thermal temperature sensor. This is the safety switch that sits in the stack to cut it off if it gets too hot in the stack. This is the same switch Norcold had much trouble with and forced a recall years ago. I do NOT have one of the recall fridges, it is just a part that went bad.
To test out the theory of a bad sensor I bypassed it by directly connecting the two wires leading to it. The fridge fired up and worked perfectly. I have ordered a new switch that should arrive today.
Thanks for the help everyone!
That Thermal switch is not a recall type problem. ALL Current and older Norcolds EXCEPT the 1200/1210 models have this thermal switch. This thermal switch was on the 1200/1210, but was removed when the NEW recall control box systems were installed on the 1200/1210. Doug
