A single oven electric fan is a device that circulates hot air evenly through the oven cavity with an internal fan. This helps to remove hot spots and enhance the overall cooking experience. Does your oven have fans? If yes, will it make certain parts of the oven warmer or cooler than others when you set the temperature? Functions Oven functions (also known as cooking modes or setting) provide a range of pre-programmed options to cater for a wide range of recipes and cooking needs. These options determine how the heating elements or fan within the oven operate, making it easier to achieve reliable and precise results. The majority of ovens are referred to as "fan assisted" which means that when the oven element heats, there is an air conditioner which circulates hot air around the oven cavity to aid in cooking food. This function reduces the preheating time and ensures even cooking. There are typically two fans inside an oven; the one that distributes the hot air to assist cooking and a cooling fan which is controlled by a thermostat switch and turns on automatically when the thermostat knob is set at anything other than off. Functionality to make life easier Ovens are able to be with a range of features that make them easier to use, for instance the defrost function that makes use of low temperatures to thaw frozen food without cooking them. This speeds up the defrosting and stops food from drying out or becoming partially cooked. The reheating mode is useful as it uses gentle heat to warm foods, helping to retain their flavour and texture. Other helpful features include a child lock function which locks the control panel, preventing children from gaining access or altering the oven's settings. A minute minder is a handy function that can be used in conjunction with of the cooking functions and shuts off the oven after an amount of time has passed
