Refrigerator Not As Cold As It Ought To Be

I know what the temp control does.

Some (many in the forums) say that sliding the thermistor up or down on the fin does something. Some say it doesn't. Neither have explained the why of their position ... they just want us to take them at their word or spend the time to run our own experiments.

I prefer to do neither without an explanation of the why of what's going with sliding of the thermistor.

What myself and many other RV propane refrigerator owners would like to know is: Can I use the temperature control to adjust the freezer temperature to what we want and then use the thermistor to then adjust the refrigeration section to the be as close as possible to the temperature that we want. It doesn't take a rocket science answer.

In short you cant change the delta of the fridge and freezer.
Well, not in terms of setpoints anyhow. You may be able to change it by using an internal fridge fan increasing efficiency, but the fridge temp thermister and control board cycles the whole unit on and off.

When on, your freezer gets full "Coldness" or heat absorption for lack of better explanation, what is left goes to the fridge compartment. Working as designed you probably see a 30-35 delta so 0 freezer and 30-35 in the fridge on a good working unit. If you want it colder you can fool the thermister by thinking it is warmer, (I have a Dometic adjustable thermister box) and the cooling unit AC or propane will stay on longer. Then the freezer will get a few degrees colder and so will the fridge, mostly at the same delta.
The experts can chime in if Im wrong.

Note, mine is a Dometic Americana Rm2652 that is not "adjustable" there is no numbers to select, just the fin thermister.
