The oven makes a popping sound.
		Do not attempt service or replace parts of the appliance unless referred to in the owner's manual. Follow all safety precautions provided in the owner's manual.
		A noise can sometimes be heard while the oven is preheating, being used, or cooling down. This is called “oil canning”. Oil canning is caused by expansion or contraction of the rear oven wall. This is a normal condition.     When using LP gas, a popping sound may be heard when the burner shuts off. This is called "extinction" and is a normal condition.
