The temperature sensor itself is detected as faulty. This means the sensor is either providing inaccurate temperature readings, no readings at all, or reporting values outside its operational range, compromising proper temperature monitoring.
Click steps to track your progress.
Measure the resistance of the temperature sensor across its terminals and compare it with expected values for the ambient temperature.
Compare the sensor's reading with an independent, calibrated reference thermometer to assess its accuracy.
Replace the temperature sensor if it is confirmed to be faulty after these checks.
