manually

something wrong with the power supply. Is the cooker supply
on at the isolator switch?
Has the time of day been set?
The timed oven is not coming on when automatic
cooking

has not worked, or has only worked for a short time, then you
may need a new thermostat. This should be fitted by a service
person.
