Out on our first trip? On gas fridge
So I have had the fridge on electric, Norcold N611, so I unplugged and switched to “ gas”... I could hear the igniter and it sounded like it lit but then the lights flashed and nada So I waited a few...

So I assume there is NO thermocouple because it has an ignotor right ?
Acoukd it have been air in the line from having the gas shutoff ?? Thx
Bad assumption.. There is a thermocouple IT MAY be the igniter rod.
Here is the start up sequence as best I recall it
Thermostat calls for COLD
(note I'm doing gas only here)
Control board opens gas valve and starts sending voltage to the spark gap. roughly 1,000 volts. Spark jumps gap and flame happens. We hope.
Possible issues. Bad solenoid valve. dirty orifice no propane or propane turned off.
Assuming good flame
Flame heats thermocouple. This may the the ignition rod or another rod near it. Thermocouple sends 0.480 volts to the control board. Board senses and is happy till T-Stat inside Fridge says "Cold enough"
Mine is 33 degrees when that happens.
Now... IF it is a SINGLE WIRE ignightion system then the Thermocouple and spark rod are the same rod.. And if the change over goes funkey the sensor chip can get hit with around a kilovolt of power.. pop goes the sensor..
Not the Fridge board but my furnace board. I'm fairly sure that is what happened. THe new board (Dinosaur boards) has a nifty little over voltage arrestor right next to the sensor chip.. I'm guessing they too think that is what happened.
