I have a norcold N300. Works fine on AC and DC. When running on LP the flame will light up and burn for a few hours and then just shuts off. Any suggestions?

could be a couple of things ...dirty / bad thermocouple clogged / burnerlow pressure propane clogged orifice first thing i do is clean the thermocouple , blow out the burner then clean the orifice ...

I have never wanted to do that, but in a week, I am going on a ten-night trip spending two nights at each of five parks. I thought you had to use gas then. I'm confused.

Did you clean the flue? On mine, I took the top vent cover off and peeled back the first six inches of the screen from the roof vent. This way I can reach down and remove the air diverter. Then use a 1/2" wire brush or wad of foam on a coat hanger to run up and down the flue a few times. Just make sure it's been off a few hours if you use the foam or you will end up with a melted mess.You may want to cover the burner area with a tissue to keep the soot from falling into the burner.If your charge wire is heavy enough to provide 12-15 amps to the fridge while traveling down the road, yes. I do it on long travel days, but my custom wiring is capable of delivering 25 amps to the TC. Jusst remembeer, the N300 on DC is constant on, so it's possible to freeze everything in the fridge when it's cool outside.
