    Haynes manual describes 3 methods of sensor drying:


    Traditional thermostats which at a certain fixed temp simply turn off current to timer/heaters

    Thermostats on inlet/outlet giving comparitive temp diff readings to microprocessor which decides when to turn off heaters/drying programme

    Drum mounted electrical contacts which measure dampness of clothes by the electrical resistance


    What I want to know is how common are these methods? / are any obsolete/not used? as some things in Haynes are virtually never seen such as vented washer dryers.

    What would be the method used on Hoover Nextra 6 washer dryers?

    cheers

    A negative temperature coefficient thermistor.

    Hi I meant
    ‘which of the general methods (that I quoted from Haynes book) is it?’,
    not ‘what was the actual sensor used?’
    but I presume since you say its a thermistor that it will be the middle method “Thermostats on inlet/outlet giving comparitive temp diff readings to microprocessor which decides when to turn off heaters/drying programme “

    cheers
