It is a damper assembly that helps to regulate the air flow in the oven. The damper is made of metal and plastic and is designed to fit into the back wall of the oven. It has two metal blades that open and close to control the amount of air entering the oven. The damper also helps to keep heat from escaping from the oven when it is not in use. This part should be replaced if it becomes damaged or worn out, as it can cause poor baking results or even fire hazards if not functioning properly. This part is a replacement for a faulty or damaged microwave damper. It can fix symptoms such as poor air circulation, loud noises, and smoke or odors coming from the microwave.
