How can I fix my Electrolux EOB944 built in oven?

I turn the Electrolux EOB944 built in oven on and set the required heat. The fan spins, the thermastat light is out (as if temperature has been reached) the oven light is on - there is no heat from the oven. I then put the dial to the grill setting and the fan is on but no heat from the grill either. Thought it may have been the heating element but that would not explain the grill not working either - appreciate any help.
