Pilot Light Not Staying Lit

[Gene]

The temp in the fridge compartment could be even higher (or lower). People install fans in the compartment. I have been told the best place is at the top of the flue.

So your refrigerator is holding a 62-degree delta below ambient in the living space of the trailer (and as Gene said, perhaps even more of a delta from the heat-exchanger compartment.) I wouldn't want to be in the trailer if it's over 100F inside, and at 100F it could probably maintain 38F or better in the 'fridge, if it maintains the same delta. That's not too bad, really.

The 122F you measured inside your trailer makes me feel much better about what I spend every month to keep a roof over mine!

Yes, I think the fridge is working great considering the conditions. I also know the thermistor is working as it should after more testing. I have found that the inside trailer temp doesn't make as much of a difference as the outside temp. This AM it was 35 degrees in the fridge. I think it would need airflow like the Snyder system to get any cooler in the hot Texas summer afternoons, but again I am satisfied with how it is performing. Also, the fridge/freezer are both completely empty at the moment so that doesn't help.

Now back to my original problem, running on gas! I received my new thermocouple today and installed it. The problem of the gas not staying lit after 30-45 seconds of turning on the fridge still remains. I also removed the burner to clean it, but it was perfectly clean. There is no air in the system as the stove and hot water heater are working great.

The electric ignition is working great and lights on the first click. I have all of the guards off so I can look directly at the burner. There is a deep blue flame from 0-1/4". Then there is a much lighter blue up to about the 1" mark. The tip of the thermocouple is about 1/3-1/2 way into the lighter blue flame.

You really can't even hear the burner, not like I can hear the jet engine of a hot water heater roaring. This is my first time to use one of these fridges on gas so I really don't know what the flame or sound should be like.

The gas shutoff valve is wide open. Could this be the valve with the two wires or the control board?

For anyone curious the problem with my fridge's gas not staying lit was the control board. I bought and installed a new Dinosaur P-711 board today (same as what was there already). Now the gas stays lit and works great! Thanks to everyone for helping me out.
