    LP cooler??

    My friend has a refrigerator for a pop up camper that can use either 115/lp/ or 12 volts.

    Its not cooling, there is no compressor but elements???

    how in the world does this thing cool from heat? elements are working fine but unit wont cool. I have no idea what they charge this thing with and I dont see any charge ports.

    Seems to me its low on whatever it uses to cool. Any help here on what it uses and how I get it into the system?

    An old timer's trick with these units is to turn them upside down overnight then try running it again the next day.

    If you turn them upside down do they become an oven?

    In other words it's a sodium or salt solution system. You heat the solution and it percolates through the lines. It still condenses and evaporates just like refrigerant but doesn't need a pump or compressor.

    You can't put guages on a sodium system and if it is an older unit it may have a leak in it somewhere. They are bad about rusting from the inside out and creating a pin hole. It can't be found with soap bubbles you have to use a small knife or screwdriver to scrape around any rusted or corrodes areas. If you think there is a hole push a paper clip through it and you will know, then go buy a new one refrigerator.

    Silly boy, you can turn it upside down to break loose the crusted sodium when you turn it back right side up the liquid will return to the heat chamber.

    Oh yeah... when are going to the store for more toilet paper??
