11.3. NTC

Component which sends signals to PCB about the water
temperature inside the tub. The Resistance (



) value of

the NTC decreases as the temperature increases.

Technical features

Testing component

Check the resistance value on the component with multimeter as shown below.

You can determine the



value by measuring from the blackcable at 3rd and black cable at 11th position in the small socket

(refer wiring diagram in section 12) as shown in below figure. NTC resistance value varies depending on temperature.
