Angry Freezer @ 46 degrees and Holding...

Any recommendations on resolving the ice cream soup issue we are having with a freezer that will not go below 46 degrees? Lots of refrigerator posts, but the bottom half seems to work fine. It's the Freezer that's unfreezed! Tired of slurping my ice cream, although honestly is makes great milkshakes...

Unless your fridge was replaced, it should have 120v/LP. Airstream didn't start across the board putting in 12v compressor fridges until around 2022 model year.

If accurate in your case, are you running it on 120v or LP? If you truly do have a 12v compressor type fridge that has no LP, I'm at a loss, but if you have an absorption type fridge, I would see if it behaves any differently in LP vs 120v mode. Make sure that airflow is good and those would be the initial steps I'd take.

Never heard of one having the freezer not work but the bottom staying cool. This is really unusual. I'm following this one out of curiosity.


On edit: you say the bottom "seems" to be working just fine... Get a thermometer and make sure its staying below 40. Above that temp, food goes bad. It would be awful for you and your family to get sick because you assumed the temps were good.
I had trouble with mine last year and on a lark put my weather station remote sensor in the fridge box (can't believe that worked!) and it gives me a great deal of comfort to be able to glance up and see the refer temp without having to open the door.

It is 12V / LP, we will switch it over and give that a shot.


It is truly odd that the bottom is working in fact it is likely colder than the top!


I will update after the LP test.


Thank you all!

If you place you hand one the bottom of the freezer, does it feel cold?
Yes to getting a thermometer to see what actual measured temps are.
Yes to propane as we find it to work better.
How is your rig oriented? Is the hot afternoon sun on the refrigerator side? How hot is it outside? Do you have a cabinet that is above your refrigerator? If so you should prop it open to help heat escape and to help your fridge/freezer work better. Same comment for your wardrobe it it's right next to your fridge. Popping that door open to let the AC air next to the fridge helps it cool off.

If that's true, it must either be a non-factory fridge or a rare bird. AFAIK, in 2018 Airstream was supplying trailers with 2-way absorption refrigerators that worked either on 120V shore power or LP gas. That's what we had in our Classic that year. A 12V connection was required to operate but it was used only for control functions and lighting the propane burner when appropriate.

In 2020, Airstream switched to a 3-way absorption fridge like I have in my current GT. In addition to 120V and propane operation my fridge will also work on 12V alone.

A short time later (2022 I think) the factory switched back to 2-way (12V and 120V), but now they are all-electric compressor refrigerators. Although there are times on really hot days where it struggles a bit to maintain temps, in general it will keep the main compartment in the mid to high 30's and the freezer will easily freeze ice and keep other stuff frozen.

I agree with the suggestions to put a thermometer in the main part of the refrigerator to see if it's really getting cold enough. Since your freezer isn't freezing, I'm guessing that it's not. Good luck.

You need to clean your burner and check the gas pressure with a manometer.

Just happened to re-read this and realized I cut and pasted badly. The bold part refers to my 3-way fridge in the previous paragraph, not the new compressor style fridges which are quite good at holding temps.

^This...plus, tap on the chimney to knock out the rust and soot.

I built my own manometer but you can buy them too. Do the cleaning and the knock first. If you have adequate propane pressure elsewhere you are likely (but not assured) of having adequate propane pressure at the fridge.

Here is a thermostat: AcuRite Digital Wireless Fridge and Freezer Thermometer. There are others.
