Ovens have a typical lifespan of 20 to 30 years. Over time, deterioration of the insulating systems and structure occurs.

• Seams in the insulated walls loosen, allowing fibers to escape into the heating chamber.
• Interior sheet metal and structures become corroded, releasing minute rust particles.
• Further, an old oven can be difficult or impossible to clean properly.

When your oven’s time is up, contact an oven manufacturer specializing in clean heat oven design, and purchase a new oven.
