Our RV refrigerator has five (5) average coldness settings via a 5-position master temperature switch. I can control the absolute average temperature of both the refrigerator and freezer (together but not separately) by selecting any one the five positions of this switch - so I probably can force the freezer down to an average of (the industry recommended) 0 degrees, if I wanted to, by using setting 4 or 5 of the master temperature switch.
However while doing this, the refrigerator temperature would then be too low (i.e. milk frozen solid). What I want to do is change the relative relationship/spacing between the refrigerator and freezer temperatures regardless of whatever position I have the master temperature switch set at.
In other words, I'd like to set the master temperature switch at whatever setting it took to have a zero degree freezer and then have the slider permanently adjusted such that the refrigerator then wound up at a temperature of around (the industry recommended) 38 degrees.
If sliding the thermistor up/down on our Norcold refrigerator does the same thing as on the OP's brand of refrigerator, then maybe I could find a position for the sliding thermistor such that the refrigerator and freezer temperatures averaged 38 degress apart for any setting of the 5-position master temperature control. Thus I could have the freezer at -2 degrees and the refrigerator at 36 degrees, the freezer at +2 degrees and the refrigerator at 40 degrees, etc., by just changing the master temperature switch settings in accordance with whatever setting it took depending upon any particular outside temperature.
I have not contacted Norcold yet on this and I'm not sure whether the thermistor silder on a Norcold unit does the same thing as on other brands of refrigerator. Hence my question in this thread - just in case someone already had experience with this approach on a Norcold RV propane refrigerator.
