    Hi all

    I have a sensor in the top of the drum which has come loose and the White plastic surround it sits in has warped. It won’t screw back in, does anyone know what should be at the back of this screw, is it just a simple nut ? I can’t work out how this sensor works as there are no wires so my question is

    Could the fact this sensor has come loose be the reason why the temperature sensor at the back has tripped ? It’s the one with a yellow spot. I had to replace these a few months ago and they worked for a while but have now gone again.

    I know there is a front sensor at 12 o clock in the door too, but I can’t work out how to remove that one for testing ?

    Any help is much appreciated !

    Sorry ! It took me so long to reduce the picture size to a point at which they were acceptable I missed the obvious !

    It’s a hotpoint tdc62s condenser dryer

    That is the drum sensor, it should be fixed to the sensing strip that runs around the outside of the drum. you would get no heat if that was missing.

    It must have seriously overheated at some point as I have never seen one of those warp before.

    I wonder if the motor capacitor is failing as well?

    Several parts included in the sensor so I have attached a picture for you to decided what you think you might need.

    Many thanks for your reply and taking the time to upload that diagram. Unfortunately I can’t blow it up enough to read it without it distorting to a point that its a blur.

    So just to clarify ( if you would be good enough ) I have obtained a new plastic piece and inserted the thread through the drum as can be seen in the attached photo. I assume its simply a nut to secure this in place, its not connected or wired in to anything. I assume its connection with the band going around the drum is enough for it to do whatever it is meant to do ?

    Thanks again

    You need to view it on a PC for best picture but TBH it is perfectly sharp and clear on my iPad as well.

    That sensor is something I have never needed to touch, it does not have any connections, it is used to allow a tiny voltage to be passed through the damp washing. as the clothes dry the resistance to this current increases, this is measured by the pcb to control the auto drying function.

    Brilliant – thank you again. I sorted the attachment out, it opened up in a small window but i then could click on it and scroll around – so all worked in the end. I will attach the sensor and then replace the rear thermostats and see if that sorts the issue
