How to Replace the Grease & Odor Filters in a Kenmore Microwave
Kenmore manufactures both counter-top and over-the-range microwaves. Over-the-range microwaves are intended to be installed over your cook-top or range, and have a hood fan and light on the underside of the microwave. When turned on, the fan helps to absorb smoke and odors from the surface below. The air flows into the bottom of the microwave and through one of two grease filters, which ensure that grease does not enter the microwave duct. The air then flows through a charcoal filter which removes most of the odors and toxins from the air before it is released back into the the kitchen. After regular use, you must clean the grease filters and replace the charcoal filter to ensure that the air always is properly filtered.
