Since the refirgerator fins are cooled by the freezer the thermistor has everything to do with the freezer. Once the thermistor senses a certain temperatue in the frig it cuts power to the freezer to maintain the frig temperature. Temperatures in the frig are dependent on the temp in the freezer.
From a RV tech with 35 years experience. There are 2 sections of a RV absorbsion Cooling unit. The Top section tubes which is the freezer which is the FIRST section of tubes that get sub cold. Then the tubes go down a few more inches and contac the lower section where the Evap fins are. THAT section is controlled by the Tstat. This is one thing, novices do NOT understand especially when they purchase a used RV. The seller has the refer ON, and shows how cold the freezer is and the inexperienced buyer assumes the refer is functioning. BUT, a BAD cooling unit will Freeze the freezer but not the lower section, and then the novice finds out he was had to the tune of over a $1000 to fix the refer. The evap fins will be 10 degrees cooler than the refer. So, if the refer is 36 degrees the fins are 26 degrees and THAT temp is what the tstat responds too.
