Inlet air - Thermistor element (PT100 sensor)

Function

The thermistor element measures the temperature of the heated air entering the drum. 
The resistance of this device is normally 110 Ohms at 20°C (68°F) and increases as the 
temperature rises.
The signal is returned to the PCB and this ensures that the inlet air does not become 
excessively hot, thus preventing scorching of garments.
