Another possibility. My uncle has a Norcold 4 door fridge in his 2007 Winebago Voyage. Maybe yours is similar.
Anyway, there was a modification performed in which a small black box was added to the system and mounted on or near the burner tubes and it's supposed to shut down the fridge in the case of an overheat condition. I believe this was a recall due to a fire hazard.
Anyway, that black box is apparently susceptible to tripping IF water is splashed onto it. This can be because of heavy road spray or washing the rig and the water is shot into the exterior fridge access panel.
I know his module has a red LED on it, but I forgot whether it's on all the time or if it turns one when the module is tripped. I guess the latter makes more sense, but I honestly don't remember the situation.
The module can be reset by putting a STRONG magnet near the module and I think you have to hold it there for a couple of second. IF the LED was on, it should go off...and vice versa. Sorry I don't remember more. I haven't had to do it for a couple of years. I think he had to do it several times as I guess the location his was mounted was susceptible to getting splashed.
Oh...I would also recommend that you edit the subject of your post to include Norcold 1200 and NoCo to get more attention.
Good Luck,
