belling double grill oven not working?

i have just moved house and there is no manual with the cooker. when i turn the dial to what looks like the grill setting the light on the cooker temp dial comes on but nothing heats up. when i turn the grill dial it works but i cannot get the oven to heat at all, or the fan to turn.its a belling electric. only markings on it say dual grill. anyone got a manual they can scan and email so i at least know i have the knobs right? thanks by the way before anyone suggests i cannot contact the ex owners cos they have emigrated.
