Assuming you are referring to a standard household toaster oven, the average lifespan is about 10 years. However, this can vary significantly depending on the brand, model, and how well it is cared for. Some toaster ovens have been known to last 20 years or more with proper maintenance.
Toaster ovens typically last longer than toasters because they have more robust heating elements and insulation. The coils in a toaster oven are also spaced further apart, which prevents them from burning out as quickly. Nevertheless, all electrical appliances will eventually wear out and need to be replaced.
Here are some tips for prolonging the life of your toaster oven:
-Only use it for its intended purpose. Don’t try to cook food in it that wouldn’t normally be cooked in a toaster oven (e.g., large pieces of meat).
-Clean it regularly. This helps prevent grease and crumbs from building up and damaging the interior components.
-Be careful with what you put inside of it. Don’t overload the racks or place metal objects too close to the heating elements.
-Don’t use it if it appears damaged in any way.
