Thermisters ???

Moving the thermistor will only affect temp IF the fridge does NOT have an adjustable temp control on upper panel (non-adjustable temp setting)

It is attached to the cooling fin in food section.
It has a sensor (bulb) on the end of tip.

It provides feedback to temp control.

Moving it up (into warmer area of fridge) will make cooling cycle longer (more cooling)
Moving it down (into cooler area of fridge) will make cooling cycle shorter (less cooling)

YET.....if it falls off and is laying down in lower section of food compartment fridge will go into continuous cooling resulting in frozen food

I would like to offer a slightly different theory, you can take both and use it to your advantage.

The cooling coil is cold. Perhaps colder in the center than at the bottom. If the cooling coil is say 25F at the back, where the heat exchanger meets with the coolant (ammonia and water mixture) then the fins collect heat and transfer it back to the colder area in the back of the refrigerator section. So the fins might be say 30 at the bottom edge (no more cooling beyond this point) and 28 closer to the center of the heat exchanger - this means that moving the sensor up will get it to a cooler area, thus shut off the cooling control sooner, while moving it to the edge where it is warmer will run it longer. Taking it off the cooling coil, and it might never reach 28F and shut off the gas valve - thus everything will freeze inside the refrigerator section.

I prefer a adjustable thermostat. If people would walk into a RV, see that the temperature is not adjustable, and complain to the person in charge of the RV sales lot, then drive away, manufactures will stop installing non-adjustable thermostats in their RV's. But as long as "We the buyers" accept non-adjustable thermostats, they will keep installing refrigerators that are $50 less than the model that has an adjustable thermostat.
