If there are no volts at the fan or element then it looks like it might be the thermostat which controls the electrics feeding them.Alternatively , if there is a timer , then this normally controls the main oven so this might be the culprit. If you have a multimeter or mains neon-test screwdriver you could fault it by testing for volts through the circuit...(.or check the element + fan for continuity ).. If you are not sure what you are doing then it`s best to call in an electrician.(If you are OK working with electrics then to prove the thermostat, it may be possible to swop the thermostat controls over from the small oven to the main one. It saves buying one )
