How it works
During the Self-Cleaning cycle, the oven gets
much hotter than it does for baking or
broiling...approximately 875°F (468°C). This heat
breaks up grease and soil and burns it off.
This graph shows approximate temperatures
and times during a Self-Cleaning cycle for 3 hours.

Notice that the heating stops when the 3-hour setting is up, but that it takes longer for the oven to cool
down enough to unlock.
