Not being plugged in might not cause it to operate on 12 volts if it's like the Nova Kool in the Interstates. To get it to run on 12 volts, one would need to turn the inverter off and be unplugged and have the generator off.

I don't know if the Grand Tour refrigerators operate the same.

In our Safari we have a single door referring/freezer, the freezer works great, but in hot temps outside, (set it in a back corner) and this greatly helped bring the temps down and keep the food cold. About every other day, we refresh the ice. To keep the ice/water from sloshing around in the container, we use either a gallon size zip-lox or a plastic bag with twist tie to hold the ice. This was the fastest/cheapest solution for us. Good luck.

I have not noticed any difference in whether it is plugged in or not. It never goes below 53 in the daytime. I have had to throw away all my fresh food. I guess we'll take it into the dealer when I get home this week.

Sounds like you DO have a problem. Danfoss compressor type marine fridges should hold the temperature in the mid 30's whether on 12VDC or 120VAC. The units that I have installed (I don't use the Tundra line) have all worked perfectly with one exception, and that was addressed at the Isotherm importer same day.

As the Danfoss compressor is basically a DC based unit, you are more energy efficient when using your 12VDC direct power than using the inverter to create 120VAC, as the compressor's electronics will only convert that to 12VDC anyway. That is why they work so well with solar.........

Camping World and others sell a small battery operated fan that runs on batteries. Set that on the bottom area of the fridge and it will "helP' circulate the cooler air, which is lower in the fridge, around inside the fridge.

Not directly related to the OP's specific issue due to different fridge model, but I am inserting this link here for future thread searchability. Tips on replacing a Dometic fridge, with installation observations from an Interstate perspective. Potentially useful for T1N owners whose original fridges are probably on schedule to develop age-related problems, as ours did.

Did you ever get this cooling issue resolved. I have the same problem on my 2015 Grand Tour. Also live in Texas. Its over 100 down her recently. Freezer works fine but the fridge won't cool below 50. Dealer told me that Airtstream has a fan kit to help vent the unit.

This problem is unique to the Grand Tour models that have separate refrigerator and freezer, and if you have one of the early Grand Tours from before they started adding the fan kit at the factory, you definitely need to get the kit.

Fan Kit explained

I also have a 2015 Grand Tour refrigerator that did not cool. I had the fan kit installed by my dealer last fall. The process involved replacing the blank wood access port (under the freezer) to the water pump with a louvered access port. Louvers (with fans) were installed above the fridge. Also there appears to be a second vent on the roof above the refrigerator area that looks like the bathroom vent. I don't recall seeing that vent before. All of this is to increase air flow over the freezer and refrigerator coils. Apparently the factory installation of the refrigerator and freezer did not allow enough ventilation to properly carry away the heat generated on a hot day which kept the refrigerator from cooling down to the proper temperature,

I have not had the Interstate out this year on a hot day to confirm the improvement but I am confident my problem is solved.

BTW this was a warranty repair.

I am back home and have been in touch with camping world. They installed the new fan kit recommended by airstream, made the vents larger and replaced my refrigerator last October. The refrigerator works as long as the ambient air does not go above 60 degrees. My refrigerator temp went to 60 degrees while I was in Texas. I kept things cool with frozen bottles of ice and a bowl of ice. Camping world sent a message to airstream and I will follow up tomorrow with a phone call. I would love to hear from anyone with this problem, so I can show airstream that this is not an isolated issue

I hope they get this sorted out for you because that is definitely not right. I'm in Texas and my old-tech propane Dometic has a bad habit of freezing solid the contents of my refrigerator.

I don't think anyone stated the make and model of the fridge in question. My husband and I are always coveting those separate fridge-and-freezer models, so if there's a particular model that is prone to issues, I'd like to know which one.

Most likely the thermostat. I had the same issue on my 2015 and called Nova Kool. Nice gentleman answered the phone and shipped me a free replacement part in three days. I swapped it out myself, not the easiest thing Iv ever done but fixed it.

Curmugeon -- I really appreciate hearing from you that the refrigerator cooling fan kit for the 2015 Grand Tour is an Airstream warranty retrofit. I immediately contacted my dealer to inquire about the retrofit for my AI, and it is being promptly shipped out from the factory for installation within the next few weeks.

Tim, please let me know if the retrofit works, as I had all that done and a new refrigerator put in last October and the unit still does not cool in hot weather
