Refer not maintaining temp.

We are on our initial trip with a 2015 Interstate. The refrigerator will not maintain temperature but the freezer works well any trouble shooting suggestions?

Make sure and level the rig to the refrigerator. If ours isn't within half a bubble of level it will not cool properly.

The fridge in an Interstate is electric only (compressor type) and doesn't need to be level.
Is this a Grand Tour with separate fridge and freezer?
Take a look at this recent thread for ideas:

Is it a Grand Tour model that has separate refrigerator and freezer units? Or a regular Interstate that has one Nova Kool fridge with a tiny freezer tray on top?

I ask because on another thread, someone with a Grand Tour had the same problem. Come to find out that someone at Jackson Center had failed to hook up the 12vDC circuit for the fridge, so it would only work on 120vAC, but for the freezer, both 120vAC and 12vDC circuits were hooked up.

So, troubleshooting tipÖ check the fridge in both 12vDC and 120vAC modes, and see if it's a problem with both power sources, or just one. To check in 12vDC mode, shut off the 120vAC circuit breakers; that forces the fridge into 12vDC mode by default.

I highly suspect that it's a double unit (Grand Tour) since in the single unit, the freezer is what cools the entire unit. So if the OP's freezer is working and the frig isn't, they must be separate.

Not necessarily. I've had it happen in my single unit. Once. The culprit there was the fridge was loaded to the gills, packed tight without enough space left for proper air circulation. That was back before I had my toad, and I was trying to pack enough food for a nine-day trip to avoid having to break camp for a grocery run. That plan kind of backfired.

I installed a wireless temperature prob to monitor constant the fridge. It works well but I can see a difference between 12v and 120v so I just run it on 12v all the time.

Is there a way to make the switch from 120v to 12v (other than by disconnecting shore power)? I haven't compared the temp performance between the two, but would obviously like to select the mode which maintains temp the best. Thanks.

Some folks on this forum have simply unplugged the 120 volt line on the reefer. also it will run on 12 volts DC if the inverter is not on and you're not connected to shore power and the generator is not running.

It's also more energy efficient to run it on 12 volts DC as the 120 volt line is inverted in the refrigerator to 12 volts DC.

I installed on if the outlet switches. If the light on the switch is on I am running 120v if it on so when I boondock I make sure it is off and run the inverter keeps the batteries above 50% next morning.

Since the inverter runs off of the batteries, how does running the inverter keep the batteries above 50%? Or did I misinterpret what you wrote?

If I boondock leave the fridge on 120v running the inverter will leave me in the morning with some tv usage under 50%. So turning the 120v off will leave me above 50%.

We are on a trip and are in Texas . 90 plus degrees weather and my refrigerator cools to 47 at night plugged into the campground and 53 during the day plugged into my daughters house. The freezer is working perfectly. Do I have a problem that needs to be addressed or is this normal with the heat.

I would say it's a problem. Recommended temperature for a refrigerator is 37F wherever you are. The food will be rendered unsafe to eat at a much higher temperature.
Is this a Grand Tour? It seems a few are complaining of issues with the refrigerator.
The air inside needs to circulate, so if it's overloaded with food, that could also affect it.
Have you noticed whether it seems to operate better when you're not plugged in? Wondering whether running on 12V makes any difference.
