This thermistor is the refrigerator temperature sensor that helps the control board monitor and regulate cooling. Replacing a failed thermistor restores accurate temperature readings for more consistent fridge and freezer performance. What it does:

• Senses internal air temperature and sends that information to the control board
• Helps the defrost and compressor cycles run at the correct times
• Commonly linked to symptoms like inconsistent temperatures, error codes, or a unit that runs constantly
• Does not control cooling directly but provides the temperature feedback the system needs

• Always disconnect power to the appliance before beginning service
• Typically located in the fresh food or freezer compartment near the evaporator
• Handle the sensor and wiring gently; avoid pulling on the wires or bending the probe sharply
• If troubleshooting, verify wiring and sensor resistance per the manufacturer's service instructions before replacement
