A:Answer Hello Jeannie. There are several sounds that are normal to hear in range and oven operation.
It is normal to hear the temperature control click on and off during the baking, broiling, convection cooking, and self-cleaning cycles.
The sound of a fan running during the self-clean cycle is normal.
The sound of a fan running during and after the oven is on. The fan keeps the electronics cool.
"Crackling," "popping," or "oil canning" sounds are caused by the heating and cooling of the metal during the cooking or cleaning processes and are considered normal.
Thanks for checking. Olga
