Oven thermostat control light
This light goes off when the oven heats up to the temperature set and comes on again every time the thermostat cuts in to stabilize temperature.
Operating control light
It indicates that one or more of the heating elements are turned on.
The safety thermostat
In order to avoid excessive overheating due to incorrect use of the appliance or else to a faulty component, the oven is equipped with a safety thermostat which cuts off the power supply if necessary. Operation is restored automatically when the oven temperature decreases to normal values. Therefore, if the thermostat cuts in because you have not been using the appliance correctly, the oven can be used again simply by waiting for the appliance to cool down. If, instead, the thermostat cuts in because of a faulty component, you should call the Service Department.
