The Control Thermistor is an OEM part for Frigidaire dryers. This component plays a critical role in regulating the temperature inside the dryer by monitoring the internal conditions and sending temperature data to the control board. The control board then uses this information to adjust the heat cycle, ensuring clothes dry evenly and safely.  Symptoms of a failing control thermistor include: Clothes not drying properly or cycles running too hot or too cold Frequent stopping or starting of the dryer Error messages related to temperature or sensor issues displayed on the control panel Causes of control thermistor failure generally involve faulty wiring, accumulation of lint and debris affecting the sensor's accuracy, or wear and tear from regular use that leads to degradation of the sensor components. This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.Part Number 134587700 (AP3866842) replaces 1156925, 134216500, AH1149368, EA1149368, PS1149368.
