To test the thermistor (part number WP8577274) with an ohm/volt meter, start by disconnecting the two wires attached to it. Next, check the resistance of the thermistor using your meter. The resistance values will vary depending on the temperature. Here are the expected resistance ranges:

  • At 50°F: 19.9 ohms
  • At 60°F: 15.3 ohms
  • At 70°F: 11.9 ohms
  • At 80°F: 9.2 ohms
  • At 90°F: 7.4 ohms
  • At 100°F: 5.7 ohms
