  • Moisture in connector
  • Worn insulation

How to fix it

  1. Unplug and inspect the thermistor connector for moisture or damage.
  2. Dry the connector if wet.
  3. Test resistance: if less than 1kΩ at room temp, replace thermistor.
⚠ When to call a pro: If replacement does not fix, the control board may need service.
