it is NOT recommended to re-set thermostats, there is a reason it failed, and if a one-shot thermostat goes open circuit, there is a possibility it has damaged the cycling stat. stay safe, replace the stats for under £15.00

power off, romove little panel (2 screws) at centre of back plate, then remove other larger panel that the small one sat over. Inside this larger panel is the heater held on by 2 screws on the outside. In behind the heater is the two thermostats. One of the stats has a tiny hole in the centre. push a pin through the hole until you hear a click. your dryer will now work.
