Samsung Microwave Charcoal & Grease Filter Replacement — What This Part Does

The charcoal filter in a Samsung over-the-range microwave removes smoke, odors, and fumes from air that recirculates back into your kitchen when the unit is installed in a ductless configuration. Samsung states this filter cannot be cleaned and must be replaced every 6 to 12 months depending on cooking frequency. The grease filter is a separate aluminum mesh component on the underside of the microwave that captures grease and oil mist. Unlike the charcoal filter, the grease filter is washable and reusable. Samsung recommends cleaning it regularly by soaking in hot water and mild detergent. Both filters work together to keep your kitchen air clean, but only the charcoal filter is required for recirculating installations. If your microwave vents through ductwork to the outside, you may not need a charcoal filter at all.

Signs It Needs Replacing

Lingering cooking odors after using the vent fan When the charcoal filter is saturated or old, it can no longer absorb smoke and odors, so smells stay in your kitchen even with the fan running.
Filter reminder message or indicator light on the display Samsung models with a filter reminder will alert you when the service interval has been reached, and the reminder can be reset by pressing and holding 0 after replacement.
Reduced airflow or weak suction from the vent A clogged grease filter restricts airflow and makes the fan less effective, even if the charcoal filter is new.
Visible grease buildup or discoloration on the aluminum mesh filter Grease and oil mist accumulate on the reusable filter over time, and if not cleaned regularly the filter will appear dark, sticky, or caked with residue.
Microwave has been in ductless mode for 6 to 12 months Samsung recommends replacing the charcoal filter every 6 to 12 months based on normal use, or more often if you cook frequently or prepare odor-heavy meals.
Charcoal filter is damaged, torn, or crumbling If you remove the filter and find cracks, tears, or loose carbon material, the filter has failed and must be replaced immediately.

How to Replace It

Unplug the microwave or switch off power at the main circuit breaker before starting any filter service.
Open the microwave door to access the underside and top of the unit.
Locate the upper vent grille at the top front of the microwave and remove the two or three Phillips screws holding it in place (screw count varies by Samsung model).
Slide or lift the vent grille out to expose the charcoal filter compartment.
Remove the old charcoal filter by pulling it straight out or releasing any retaining tabs, noting the angled orientation and which edge faces forward.
Insert the new charcoal filter into the same slots in the same angled position as the original, pressing firmly until it seats completely.
Reinstall the upper vent grille and tighten the Phillips screws securely.
If cleaning or replacing the grease filter, remove the aluminum mesh filter from the underside by releasing the latch or sliding it out, then soak it in hot water and mild detergent, rinse, dry, and reinstall (or install a new one if damaged).
Restore power to the microwave, reset the clock if needed, and if a filter reminder is displayed press and hold 0 to clear the alert.

When to Call a Pro

Filter replacement on a Samsung over-the-range microwave is straightforward routine maintenance that most homeowners can handle with a screwdriver. Call a pro if you cannot locate the filter compartment, if the vent grille will not come off, if you are uncomfortable working on a unit mounted above your range, or if after replacing both filters you still have poor airflow or odors (which may indicate a ductwork blockage or a failed fan motor).
