Check that you have power going to the oven by seeing if the oven neon or main oven light illuminates. If fitted see if the timer is illuminated. If there is power to your timer check that the “auto” or “A” symbol does not appear in the timer as this will stop the oven working until the timer has been set to manual (for full details on how to re set your timer please see the user instructions). Service calls to set the timer are not covered by the warranty.
