Norcold not staying cold

[pnpnull]

I have a 2016 Cruiser 351MK Touring Edition. There is a Norcold 1210 4 door refrigerator in the kitchen slide. I'm having trouble keeping the fridge cold while the freezer is working fine. I've taken the outside vents off & also switched between electric & LP. Yesterday in 90 degree heat I had 26 degrees in the freezer & 50 degrees in the fridge. Any suggestions appreciated.

It could possibly be the thermister. Here is a link on how to check it.

There were a couple modifications made to the installation of the Norcold about that time. One was a flue modification that involved adding a piece of material to the upper vent area to aid in the chimney effect. It was a piece of paneling stapled part way over the opening. Mine fell down, and I just replaced it with tin. This addon is important. I read on a post where people were actually taking them off, thinking it was blocking air.
Also, a fan was installed, thermostat controlled. If you don't hear a fan running, you should add at least one. Many people find improved performance when they add a fan, or better yet, an aftermarket fan kit.
Air flow is critical, and the problem with fridges in the slideouts is they can't have a roof vent, and they are often under an awning. Getting the air flowing in the flue makes a big difference.

Here is one fan upgrade link. Any cooling or air movement can make a big difference.

And another, this one shows the chimney add on.

One recent owner post stated that after other LP appliance trouble, found low pressure and new regulator installed made refrig work colder than ever before.

Make sure they left at least one inch clearance at back of fridge for cooling. Had to move mine ahead one inch. Mine was installed right against wall.
