Is the sensor a separate component?  On the EC1302 and 
several other models, the sensor is
a separate piece that fits up through the center of the 
heater and poked into the back of the
replaceable tip.  I got one for that iron years ago from, I 
think, Newark.  So, you might try
at Farnell and see if they have spares.
