Hi I have an Indesit FDU20iX Double Oven - Possible faulty Thermostat?

Main oven not heating up at all, fan turns and oven light comes on, also door switch is ok as it activates the fan when closed.

I have checked the Element which looks OK and also with a multimeter which gives a fixed reading back in Ohms, so no open circuit. Also have not had my RCD trip out.

How can I test a thermostat, as I suspect that it is faulty, as everything else works fine, just the oven heat light never lights up. Normally this goes out after the oven reaches the correct temperature.
