Norcold 3 way.

The lp and a.c. both work. The display works and no codes. Fridge is warm inside. The bus was on a slant when i restarted it with a.c. then lp. Did it get an air bubble or something. It worked fine before i turned it off. It was off about a week.

Pull the unit and turn it upside down.

Leave it sit that way for a week.

Then turn it back right side up and try it again after 24 hours.

If it still doesn't work, repeat the process.


Basically these units work by getting a liquid hot in the boiler chamber, then it converts to a gas and it rises to the top. As it cools down the effect is what makes the fridge cold.

However there are impurities that can build up and clog the tubes (especially if it is ran when not level or close to it).


Flipping it upside down a couple of times (and giving it a chance to fully drain both ways) will often work to get them working again.

You can also use a digital clamp meter to make sure that the electric boiler element is working (they do burn out and sometimes need to be replaced).

Likewise if the propane is not burning hot and clean (the orifices often get plugged) you may need to clean and adjust the gas flame so that it gets hot enough to do the work.

If it works on propane but not electric (or vice versa) that is the usual cause (if the control module is not bad).

But my first guess would be that your tubes are blocked so I would try the pull and flip technique.


Good luck!

Would a conventional small fridge like a small Haier be a better choice ?

I don't think so. I like the 3 types of power option. I try not to use my invertor if i don't have to.

I agree with the comment about flipping it. Been there a few times and it works usually overnight, not a week. maybe longer is better,not sure though. Guess I got lucky.
It is a pain to remove all the trim etc but better than a new fridge. I bet you park it level after this episode.

No matter what the power source is, the coolant gets heated and when a bubble appears, no circulation happens in the system.

Good luck getting it going again, no need for a new one or parts either.

Is expensive volts wise. Shore power isn't always an option. It's even fewer moving parts.
