The F9 code on a Whirlpool oven indicates that the oven door is not fully closed. The door must be closed completely in order for the oven to operate properly. If the door is not closed properly, the oven will not be able to maintain the proper temperature, and the food will not cook evenly. The F9 code is a safety feature that prevents the oven from operating if the door is not closed properly.
