Answer Dave, the evaporator thermistor WPW10383615 would need to be tested for resistance to identify if it is reading properly. The thermistor, at room temp 77°F and have an ohm value of about 2700O, or at 36°F (in ice water) with a value of 7964O. The meter should be set at a higher range than the highest ohm rating of the part so that would be 10,000O (10k). Read More... Answered by AppliancePartsPros.com | Tuesday, July 21, 2020
