Samsung Refrigerator Evaporator Thermistor (Refrigerator Compartment) Replacement

Introduction

This guide shows how to replace the evaporator thermistor in your Samsung refrigerator.

Some Samsung refrigerators have two evaporators: one for the refrigerator compartment and one for the freezer. This guide is for the refrigerator evaporator thermistor.

This thermistor does not sense the refrigerator compartment temperature. Rather, this thermistor senses the evaporator coil temperature. If this thermistor fails, your refrigerator won't cool the refrigerator compartment properly.

This guide will work for most Samsung Refrigerators . This guide is based on a model RF28R7201SG Refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same
