Thermistor reading out of range
Common Causes
- 1Failed thermistor (temperature sensor)
- 2Open or shorted thermistor wiring
- 3Corroded sensor connector
- 4Water ingress on the sensor body
Step-by-Step Troubleshooting
- 1
Locate the thermistor at the drawer base and measure its resistance
- 2
Compare the reading against the expected value for the current water temperature
- 3
A reading that does not track temperature, or an open or shorted result, confirms a failed sensor
- 4
Inspect the sensor connector for corrosion and reseat it before condemning the part
- 5
Check the harness run for moisture that could be shorting the signal
Pro Diagnostic Tip
A2 means the control can no longer trust the temperature reading. A thermistor whose resistance does not move with temperature, or that reads open or shorted, is the failure — reseat the connector first to rule out a bad contact.
