There is a heat fusible link attached to the top of the heater resistor. Check that with a multimeter it is most probably blown. also Check the heater motor runs freely check the bottom bearing is not dry and lubricate if needed. the fusible links are available from Farnell but cannot be soldered on as soldering will most probably blow the link. with mine i used a couple of block connector segments, and yes i have just fixed mine
