NovaKool Fridge Cycling 2019 Travato 59G

[SilverWinnie]

Has anyone had experience with a NovaKool RFU6209 DC 2-door fridge and rapid but intermittent cycling off and on, sometimes at 10 to 20 second intervals? Even on shore power? It sounds like it's just the fan cycling some of the time, but I can also hear the compressor starting and stopping some of the time, too.
This is the fridge that came with our 2019 Travato 59G and we have replaced all of the parts; fan, resistor, thermostat, and controller. We also installed new house batteries and checked the seals and door fitting. All to no avail. The fridge stays cold, but the constant start and stop condition will sometimes go on all day or night. Then it seems to act normally for a little while. Ambient temp doesn't seem to play a role as it happens even when it's 55 degrees outside. Our local RV repair shop has been useless with this issue and two other shops we contacted seem to think there is nothing wrong. NovaKool has been helpful with troubleshooting, but now says the only thing left to do is buy a new fridge. I would like to know if this is a typical RV fridge issue and/or if there are other brands of RV refrgerators standard to the Travato 59G that may perform better.

Sounds like a good one and hearing they tried to help is often good to hear!
But then I also find trying to help is as much a PR act as it is not truly real people who know what is needed. Maybe sales folks as much or more than repair folks?

So I fall back to DIY on a number of things!
Looks like you have the good info to ID a manual when you find the correct one! Good start!
I found this sheet of various frig manuals and went to troubleshooting 2018 to current. Thinking you frig might fit that age group?
That section has this chart to first test the DC operation than AC.

Does this fit anything the builder had you try and in an organized way?
This might be the best way I would see for a DIY test to check what I might find.

As a small side point that I have found in my work? Things can get corroded or a bit loose where we don't expect them. When checking things like fuses of breakers, wires, etc. give them a bit of close look and maybe wiggles them a bit.
You could have just enough corrosion at some point or maybe just a wire that is still almost broken but sometimes good, sometimes bad?
Hit and miss stuff is the worst but you may get lucky enough to avoid the trauma of replacing the frig and that is worth a lot for poking around at things.

This is a group that always likes to know how it goes, so please do tell us some good stories if they come around??

I did a Google search for “ NovaKool Fridge Cycling” and saw lots of folks with this issue, and lots of suggestions.

This seemed to be a common solution - thermostat location issues.
