Customer Questions and Answers for Air Conditioner Evaporator Temperature Sensor by Frigidaire

This is a thermistor-style temperature sensor that monitors the evaporator coil temperature in a room air conditioner. It sends temperature readings to the control board so the unit can regulate cooling cycles and prevent the evaporator from freezing over. Replace this sensor if the air conditioner runs continuously without cycling off, fails to cool properly, displays an error code, or if the evaporator coil ices up excessively.
