Should I test the thermistor in our Kenmore Elite dryer ...

+

May 08, 2009· and access the thermistor. To test it, pull one wire off and measure the resistance across the leads of the thermistor. Most thermistors for Kenmore Elite dryers will measure between 10K ohms (10,000 ohms) and 12K ohms at room temperature. If the thermistor is way out of this range, then it is likely bad and will need to be replaced.

How to Test a Thermistor Learning about Electronics
