Range - Fan Noise and Normal Operation
Only electric ranges have the PreciseAir Convection System. When convection baking, the fan reverses direction to allow air to circulate around the food. Performance testing has shown reversing the fan produces more evenly-browned, baked goods.
On some models of dual-fuel and electric ovens, the oven convection fan comes on immediately. On some models, the fan is also used during preheat.
On all gas models, the fan does not start until preheat is reached. On the gas range, the fan will cycle off every time the unit calls for heat.
All Other Fans
Many GE range products use fans to cool down the internal components. Some GE ranges use fans to help cool an oven or range after self-cleaning. The fan or blower could come on during any operation.
The oven-cooling fan for the electronic controls is controlled by a thermostat. The cooling fan may run throughout the entire bake cycle and continue even when the oven is off. This is considered normal operation.
