How To Test Frigidaire Thermistor 134587700
Newer Frigidaire and Kenmore dryers use a thermistor sensor to control the temperature inside the dryer. A thermistor is a type of resistor that varies it’s resistance with the change in temperature. When the thermistor fails, it can cause the dryer to not heat at all, get too hot, or sometimes it will throw an E24, E25, or F02 error code (open or shorted thermistor) on some models.
Here is how to check/test the Frigidaire 134587700 thermistor:
- Before working on your clothes dryer, make sure it is unplugged.
- First remove the thermistor sensor from the dryer. The thermistor is located on the blower housing next to the blower wheel.
- With the thermistor removed from the dryer, you will need to use an ohm meter or multi-meter to measure the resistance of the thermistor.
- Place one of each of the probes from the meter on each terminal of thermistor. With the thermistor at room temperature, the thermistor should read approximately 50-53k ohms. If the thermistor is off by more than 10% then the sensor will need to be replaced.
Here is a reading from a bad sensor (0.05k ohms):
