To use the self-cleaning function on a Frigidaire self-cleaning oven, remove all of the oven racks except those that are constructed of porcelain. Set the oven control to clean, and select the cleaning time or choose a cleaning level, then select start.
A self-cleaning oven uses a temperature of 900 degrees Fahrenheit during its cleaning cycle to burn away baking spills without the use of chemicals. Some smoke will emit from the oven during the cleaning process. The oven features a mechanical interlock that keeps the oven locked during the cleaning cycle to prevent burns. A normal cleaning cycle takes approximately three hours to finish. The mechanical interlock releases after the oven cools down to 600 degrees Fahrenheit when the cycle is complete.
