Because the oven temperature cycles, an oven thermometer placed in the oven cavity may not show the same temperature that is set on the oven.
It is normal for the convection fan to run while preheating during a regular bake cycle.
The convection fan motor may run periodically during a regular bake cycle.
The fan turns off if the door is left open during baking. The fan turns back on automatically once the door is closed.
Avoid opening the oven door more than necessary during use. This helps the oven maintain temperature, prevents unnecessary heat loss, and saves on energy use.
