Hi Richard, not familiar with the Belling in particular but a common problem with main ovens is that the user has inadvrtantly mucked up the clock/timer. this means that no power of any kind will reach the oven until the timer is properly set to a time and you ensure that it is not on 'timer / function'. In other words the oven is siting waiting for you to enter a start and finish time for the programming. So ook through your manual and fuly understand the timer set up. Otherwise, it could be a complete switch failure. You would need to replace the main oven thermostat/switch. hope this helps. use my name and an email 'at' then ati-group 'dot' co 'dot' uk. Rgds Fred
