Range & Wall Oven - Fan Noise and Normal Operation
When using the oven on your range or wall oven, you may hear the sound of a fan running. This is normal. Many ovens offer convection cooking features so they will have a convection fan inside the oven. Cooling fans are a part of the design of many ranges and wall ovens. They help to keep the components or controls from getting too hot. Below is some information about fan noise and operation.
Only electric ranges or wall ovens will have the Precise Air 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. Other types of convection fans will only turn in one direction and some may run at different speeds.
On some models of dual-fuel, electric ranges and wall ovens, the oven convection fan comes on immediately. On some models, the fan is also used during preheat. The convection fan will typically operate during all convection cooking modes. The convection fan as well as the heating elements will shut off when the oven door is opened and turn back on when the door is closed. During convection cooking modes the fan will run to a specified on/off cycle, dependent upon the cooking mode being selected.
On all gas models, the convection fan does not start until preheat is reached. On the gas range, the convection fan will cycle off every time the unit calls for heat.
It is normal for the fan to cycle on and off frequently during the convection cooking cycle. Algorithms decide when elements and fans should run to create the optimal heat distribution within the oven cavity.
All Other Fans:
Many ranges and wall ovens use fans to cool down the internal components. Some models use fans to help cool an oven or range after self-cleaning. The fan or blower could come on during any operation. The 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.
Note: Gas and Dual Fuel free-standing ranges do not have cooling fans. These models have a model number that starts with letters such as JGB, PGB and P2B.
