What happens when the temperature control switch is turned on?

When the temperature control switch is turned on, the heating indicator light illuminates as a visual signal that the heating elements are engaged and that the oven is actively heating. This labeling serves as a crucial feedback mechanism, allowing the user to confirm that the system is functioning correctly and that the desired temperature settings are being activated. The illumination of the heating indicator indicates that power is being supplied to the heating elements, leading to the generation of heat needed for cooking or baking.

The other options involve actions that do not happen as a direct result of turning on the temperature control switch. For instance, when the switch is activated, the heating elements are in fact functioning, rather than stopping. Additionally, the convection oven activates independently of the temperature control switch being turned on, and the blower wheel is likely to operate concurrently with the heating elements to facilitate even heat distribution, rather than turning off.
