hi i have a indesit gas cooker k6432gx and it wont stay alight as soon as you let the knob go, if i turn on grille which works fine and then go staright from grille to oven the oven will stay alight for about 10 seconds then turn off, any idesa, been told it will probably be a thermocouple, if it is can u use universal thermocouples for this

thanks
