Understanding fan or humming noise in oven

Understanding Oven Sounds

 

If you hear a humming noise, fret not. The cooling fan may be operating or running. The oven is equipped with an automatic cooling fan that runs when the oven is in use and/or after a cycle completes.

 

It’s normal for the automatic cooling fan to run when the oven is in use and/or after the cycle completes. It’s also normal to hear the automatic cooling fan move air when the oven is in use and/or cycle completes.

 

The automatic cooling fan helps to cool the enclosed oven cavity and the electronic controls when the oven is in use and/or after the cycle completes. It also helps keeps the electronic controls cool during every oven function such as BAKE, BROIL or CLEAN.

Note: In many wall ovens, if the oven door is left open to cool the oven, the cooling fan will not shut off.

Humming or Fan Noise in a convection oven

It is normal for the convection fan to operate during preheat when using non-convection functions. You may also hear the convection fan operating or cycling in ANY cooking function.

The reason the convection fan runs is to provide better baking and cooking performance. The convection fan may cycle on/off for short intervals during preheat, depending on model, to optimize preheat times and provide uniform oven temperature. It may also run or cycle in ANY cooking function, besides just a convection cycle. This does not change cooking time on non-convection functions.

 

The convection ovens that may experience this noise include:
  • ANY gas or electric freestanding range or wall oven with convection.
    • ELECTRIC convection fan turns on immediately.​
    • GAS convection fan turns on after approximately 5 minutes to allow proper burner flame establishment.

 

Typically, the fan operates during preheat for both non-convection and convection functions. It then turns off when the oven door is opened.

During preheat or when convection cycle is selected, the convection fan will come on:

  • ELECTRIC convection fan turns on immediately.
  • GAS convection fan turns on after approximately 5 minutes to allow proper burner flame establishment.
