Hi, Bit confused by your terminology. Does after market evaporator motor = evaporator fan motor or do you mean the compressor? Does condenser motor = condenser fan motor? The condenser fan is used to cool the condenser if it is too hot as this reduces the efficiency of the cooling system and you’re more likely to have “too warm” problems and not “too cold” problems What is the temperature in the refrigerator compartment like when the freezer compartment is too cold? It could be a sticking damper that is preventing the cold air getting into the refrigerator compartment from the freezer compartment and therefore the freezer gets colder. Alternatively it may be that if the temp in the refrigerator compartment is too warm (or the control board “thinks” that it is then the compressor will keep operating so that the cold being produced by the evap unit in the freezer can be blown into the refrigerator compartment by the evap fan, to cool it down. By doing this the freezer compartment will also get colder as well. I realize that you said that you replaced all three of the temperature sensors but did you also check the wiring connections between the temperature sensor - part #233 freezer section diagram and the temperature sensors part #236 & #237 - fresh food section and the control board in case there is a loose or faulty connection? Here’s a link to the mini service manual that is used for your model refrigerator, that may help as it shows the resistance values of the temperature sensors at the different temperatures, the wiring runs in the cabinet and the circuit diagram. Hopefully a start
