I have not checked the CPAP machine, but the oxygen concentrator uses about 100 watts or a little less when running. Our 200 AH LiFePO4 battery should be sufficient.

Originally posted by StephenH Yes, I am sitting looking at the thermometer and the inside of the refrigerator is at 38 degrees F on the top shelf. I use an indoor/outdoor thermometer and use the outdoor sensor in the refrigerator.

That is a good way to monitor, we do the same.  Don't have to open the door to 'feel' how cold it is inside and then let all the cool air out in the process.

So do these 12V compressor fridges run on propane also or only on shore power?

As another thought, and I am no expert, I have seen many mentions about the controls on the refrigerators requiring the battery to be charged even if on AC…please check to make sure your battery cut-off switch is not in off position( if you have one installed) or battery is not dead to rule this out first.

I was having trouble getting a decent flame on our stove a few years ago and found a kink in the line to the stove from the main copper line under the camper.  I fixed that and the issue went away.

If you were having problems with the LP gas regulator up in front of the trailer by the gas tank I would think that all your gas appliances would be operating abnormally.  Like a low flame on the stove, furnace, and water heater. Maybe a LP gas dealer could verify the gas pressure down stream of the regulator? Good Luck hope you find the problem. 

Jon, when I first had this issue, the pod was 7 years old and I always left the propane line on, even during the winter.  Near the end of the 7th year (2017) I hardly had any flame on either stove or fridge.  Upon disassembling the line the goes from the regulator to the fridge I had the 'goo' dripping out of the regulator as well as the line leaving the regulator going to the fridge.  The line was blown out but the regulator had to be replaced. 

How is your flame on either the stove or hot water heater?  Have you added screens to the back of both your air flow panels on the back side of the fridge?  This will keep out bees, spiders and such that can make either nests or webs that will drastically affect the flame in your combustion area as well as muck up the cooling tower that the flame runs up into. 

Check both regulator and line leaving regulator first, disconnect both ends of that line and see if anything comes out when compressed air is added.  Secondly, especially if you have NOT added screens to those two panels, take a can of compressed air, or your air gun if you have a compressor and blow out the combustion area as well as the cooling tower, top to bottom and then bottom to top after the chimney is removed (simply find the single phillips screw that holds the chimney on and then remove the whole thing.  A swirly silver rod is attached to the top of the chimney, make sure that is clean and shiny.
