Customer Questions and Answers for Thermistor (Temperature Sensor) by Frigidaire

This thermistor is the temperature-sensing component that feeds accurate readings to the appliance's control. Replacing a faulty sensor restores proper temperature feedback, helping the control run cycles correctly and reduce temperature-related performance issues. What it does:

• Monitors temperature and changes resistance with temperature (NTC), sending a signal to the control board
• Helps the control regulate heating or water-temperature management during operation
• When open/shorted or out of range, can trigger temperature/sensor error codes
• Symptoms include inconsistent temperatures, long run times, or cycles that won't complete

• 1 thermistor

• Disconnect power before servicing; shut off gas/water supply if applicable
• Access the sensor per your model; it's typically secured by a clip or screw and connects via a wire harness
• Note wire orientation; avoid pulling on wires and ensure the connector is fully seated
• After installation, clear any stored error codes and run a diagnostic or test cycle
