Ntc Probe; Drum Light - Electrolux 6 Series Service Manual

4.7 NTC probe

This sensor is fixed to the hot air fan screw. It comprises a heating element, inserted in a metal capsule, with
a value that decreases as the temperature rises. The electronic circuit reads the value of the heating element
(which depends on the temperature inside the tumble dryer) and when it drops below a certain value, cuts
the power supply to the heater unit. As the air cools, the value of the heating element increases, and when it
reaches a certain value the electronic circuit restores the power supply to the heater unit. This occurs every
time the temperature inside the appliance exceeds a given value, which varies according to the drying cycle
that has been selected.
