Fridge operation at altitude.

[fleagalbaum]

I had a weird experience this weekend.  I cooled my dometic 2201 fridge down at home then packed it sparsely, it kept cool travelling one hour to the campsite and then I turned it to propane for the weekend.

Anyways the fridge temp started to drop from 4 degrees to around freezing and dipping above and below freezing .  I kept turning the dial so it would warm up, amost to the 0 mark and the fridge kept getting colder.

I was wondering if Altitude would do this as we were at around 6000 feet.


I have it running on propane here at home at 900 feet to see if it will do the same
Any ideas?

 I just checked the fridge and with it 20 degrees C outside, and the knob at 4, it is 0.1degrees inside the fridge.  (the fridge is empty.)

could it be too much gas pressure?

Was the air temperature colder?

Mine seems to work worse at altitude, not that that has anything to do with how yours works.  

Do you have one of those little D-cell battery powered cube fans running inside the fridge?  If not, that will help keep the air stirred up, and keep the air in the fridge more even.

The other thing to consider is whether your thermometer is accurate.

I made a Manometer for checking the propane pressure at my fridge and posted info and a photo in this forum.  Search under "manometer" and you should find it.  Easy and cheap to build, and you can then dial in your pressure by adjusting the regulator.

the outside air temps were from 6 degrees to 22 degrees C

the fridge dipped down at night then rose 3 degrees during the day.

I do have one of those fan cubes for the inside of the fridge.  I pulled it out to help it warm up a bit.

Maybe I just have to set the fridge low then work it up from there.
