6802A Whirlpool Grease Filter is a removable grease-capture element used in kitchen ventilation assemblies; it is indeed a mechanical filter (typically a metal mesh or baffle-style element) designed to intercept grease-laden aerosols generated during cooking before those aerosols enter the blower housing and ductwork. As a serviceable component, the 6802A performs a primary containment function by collecting condensable and particulate oil droplets, and is sized and mounted to fit a specific Whirlpool hood or over-the-range microwave vent assembly.
Inside the appliance, the grease filter sits at the airflow inlet and directly interacts with the exhaust fan/blower, light assemblies, duct connection and internal grease tray or collector. By removing suspended grease, the filter reduces deposition on the blower impeller, motor housing and duct surfaces, wich preserves airflow performance and reduces fire and maintenance risks; conversely, an obstructed or damaged filter increases pressure drop, raises blower current draw, and can accelerate contamination of downstream components.Proper seating and material selection (mesh openness, baffle geometry, heat resistance) are therefore meaningful to maintain specified CFM and acceptable static pressure in the ventilation circuit.
This article explains the functional design of the 6802A Whirlpool Grease filter, how to verify compatibility with specific Whirlpool models, common failure and wear symptoms (reduced airflow, excessive grease loading, deformation or damaged retention tabs), practical troubleshooting steps (visual inspection, cleaning procedures, basic airflow and motor-load checks) and considerations for safe replacement (correct dimensions, mounting orientation, material properties and when to choose OEM versus approved aftermarket parts). The guidance is intended to help technicians, engineers and appliance owners diagnose filter-related problems and make informed maintenance or replacement decisions.

Function and Role of the Grease Filter in Whirlpool Ventilation Systems
The 6802A Whirlpool Grease Filter serves as a primary mechanical barrier in Whirlpool ventilation assemblies, trapping airborne oil and particulate matter produced during cooking before it reaches the blower, ductwork, and exhaust outlet. the filter operates by forcing grease-laden airflow through a series of passages where inertia and surface contact cause droplets and particulates to deposit on metal surfaces; accumulated condensate then coalesces and drains away rather than entering the fan or duct system. As an OEM replacement part, the 6802A is matched to specific Whirlpool range hood and ventilation geometries, so technicians should verify mounting tabs, thickness, and orientation against the appliance model to ensure proper sealing and airflow characteristics.
From a performance perspective, a clean grease filter maintains designed airflow and capture efficiency, while a saturated or damaged filter increases pressure drop across the ventilation system, reduces capture efficiency, and raises motor loading and noise. Typical maintenance includes visual inspection and cleaning frequency based on cooking load-heavy frying or wok use requires more frequent service-using warm detergents and low-pressure rinsing; stainless-steel elements are generally washable, but damaged mesh, bent baffles, or torn seals warrant replacement to restore performance. Common practical indicators that a grease filter needs servicing include visible glazing of grease, persistent odors, decreased vent suction, and increased fan noise, which directly affect ventilation effectiveness and appliance longevity.
- Features: washable metal construction, OEM mounting form, grease coalescence mechanism.
- Symptoms of service need: visible grease buildup, reduced suction, odors, louder fan operation.

How the 6802A Whirlpool Grease Filter Works Inside the Appliance
The 6802A Whirlpool Grease Filter is a removable metal filter located in the appliance’s exhaust path that captures condensable grease and large aerosolized droplets before they reach the blower and ductwork. Its primary capture mechanisms are inertial impaction and interception: as exhaust air accelerates through the range hood or microwave vent, heavier grease particles collide with the filter mesh or baffle surfaces and coalesce into droplets that drain away from the airstream. In normal operation the filter reduces downstream fouling and fire risk while introducing a measurable pressure drop; technicians should verify fit and orientation to maintain the designed airflow characteristics for the specific Whirlpool model being serviced.
Routine behavior and maintenance determine long-term performance: accumulation of viscous grease increases surface loading and pressure drop, which reduces extraction efficiency and can cause higher motor current and noise.Typical servicing includes removal,degreasing with warm detergent or a dishwasher cycle for metal filters,inspection for deformation or torn mesh,and replacement when cleaning no longer restores airflow or the filter no longer seats securely. Common practical indicators that the filter needs attention include persistent smoke or odor during cooking,longer clearing times for steam,or unusually high blower load; addressing the filter restores performance more effectively than increasing fan speed.
- Material and capture: multi-layer mesh or baffle design for inertial capture and drainage
- Maintenance: regular washing, inspect for damage, replace if deformed or perforated
- Symptoms of failure: reduced airflow, increased noise, recurring odors or grease in ductwork
- Compatibility: must match appliance mounting and thickness to preserve designed airflow

Common Failure Symptoms and Diagnostic Indicators for Grease Filter Performance
The 6802A Whirlpool Grease Filter functions as an accessory that intercepts airborne grease, condensate and large particulates before they reach the blower and ductwork in kitchen ventilation assemblies. In service it should allow near-unrestricted airflow while trapping oil and solid deposits on its media; once saturated or warped the filter raises resistance, redirects flow, and deposits grease downstream. Confirm compatibility by checking the filter’s mounting tabs, overall dimensions and gasket profile against the appliance’s filter frame-fit and sealing integrity are as critically importent as media condition for reliable performance.
- Reduced airflow – noticeable drop in exhaust velocity or longer clearing times for smoke and cooking odors.
- Visible grease loading – dark, continuous film or pooling on filter surfaces and accumulation on downstream components.
- Unusual noise or vibration – turbulent flow or higher fan RPM caused by increased pressure drop across a clogged filter.
- Increased motor current - higher amperage draw on the blower motor indicating elevated load from restricted flow.
- Recurring odors or smoke - reappearance of smoke/grease odors in the kitchen despite fan operation, indicating bypass or saturation.
Diagnose performance by combining visual checks with instrumental measurements: inspect for continuous coating or deformation, measure inlet and outlet airflow or static pressure across the filter with an anemometer or manometer, and compare motor current to manufacturer baseline when possible. Such as, a measurable pressure rise or an airflow reduction noticeably greater than the unit’s clean baseline suggests replacement rather than further cleaning. when replacing, verify that the new part matches the 6802A Whirlpool Grease filter’s mounting features and material type to restore original sealing and flow characteristics; cleaning is acceptable for metal mesh filters with light loading, but persistent loading, corrosion, or distorted panels require replacement.
| Item | Description |
|---|---|
| Pressure differential | Measure across the filter with a manometer; rising ΔP indicates restriction and loss of capacity. |
| Motor current | Compare blower amperage to baseline; sustained increases point to higher aerodynamic load from clogging. |
| Visual coverage | Continuous grease film, pooling, or deformation; extensive coverage typically necessitates replacement. |
Replacement Considerations, Compatibility with whirlpool Models, and Installation Procedure
The 6802A Whirlpool Grease Filter is a mechanical barrier installed in the exhaust path to capture liquid and solid grease particles before they enter the blower and ductwork. Its effectiveness depends on correct frame size, mounting-tab alignment and face-area relative to the appliance’s airflow; a filter with insufficient surface area or incorrect fit increases pressure drop and allows bypassed grease to accumulate on the fan and housing. compatibility is determined by matching the appliance model number to the filter’s mounting pattern and frame thickness rather than by brand name alone, so technicians should confirm physical dimensions and clip locations against the appliance prior to purchase to avoid reduced capture efficiency or interference with fan clearances.
Installation follows a straightforward mechanical replacement sequence but requires attention to sealing and orientation to maintain performance. Prior to final assembly, inspect the filter cage for dents, broken clips and residual oil; replace damaged hardware that prevents full seating. Some grease filters are washable metal mesh and can be degreased and reinstalled after drying,while others are disposable or include charcoal layers and must be replaced. After installation, verify there are no air gaps, secure retaining clips to prevent vibration, and run the exhaust at each speed to confirm normal airflow and absence of rattles or abnormal motor load.
- Power off and allow the appliance to cool; remove access grille or trim.
- Release retaining clips and slide out the old filter; inspect mounting area.
- Fit the replacement so tabs engage fully and the face is flush with the housing.
- Reinstall grille, secure clips, restore power and run the fan to confirm fit and function.

Q&A
What is the Whirlpool 6802A grease filter and what does it do?
The 6802A is a metal grease filter used in many Whirlpool (and related-brand) range hoods and microwave exhaust systems.Its purpose is to trap airborne grease and large particles produced during cooking, protecting the blower and ductwork and reducing kitchen grease buildup. it is not designed to remove odors – that is the role of charcoal/odor filters.
How do I know if the 6802A filter is compatible with my appliance?
Check your appliance model number (usually on a label inside the microwave cavity, on the hood, or in the owner’s manual) and search that model on the Whirlpool parts lookup or an authorized parts dealer. Enter “6802A” to see a compatibility list. If you’re unsure, contact Whirlpool support or a certified technician with your appliance model number to confirm fit and compatibility.
How do I remove and reinstall the 6802A grease filter?
Typical removal is simple: turn off power to the appliance for safety, locate the filter latch or retaining tabs (often on the underside of the hood or front of the microwave trim), depress or slide the latch, and pull the filter out. To reinstall, align the filter tabs with the slots, push it in until it seats and the latch engages. If the filter uses screws or clips, remove and replace them carefully. Consult your appliance manual if the filter does not slide or snap in as described.
How should I clean the 6802A grease filter? Can I put it in the dishwasher?
Most metal grease filters (aluminum mesh or baffle style) can be cleaned by soaking in hot water with a degreasing dish soap or a commercial kitchen degreaser, then scrubbing gently with a soft brush, rinsing thoroughly, and air-drying completely before reinstalling. Many are dishwasher-safe (top rack), but frequent dishwasher cycles can discolor or warp some filters and may not remove heavy grease as well as manual degreasing.Avoid harsh abrasives that can damage the mesh. If the filter is heavily damaged, bent, or the mesh is torn, replace it instead of attempting to clean it.
How frequently enough should I clean or replace the 6802A grease filter?
Cleaning frequency depends on cooking habits: light use – clean every 2-3 months; heavy frying or frequent cooking – clean monthly. Replace the filter if it is damaged, bent, the mesh is torn, or it no longer seats properly. As a general guideline,consider replacement every 1-2 years for optimal performance,but inspect it regularly and replace sooner if performance declines or physical damage is evident.
What is the difference between the 6802A grease filter and a charcoal (odor) filter?
the 6802A is a metal grease filter that captures grease and large particles; it is washable. Charcoal (carbon) odor filters are designed to remove cooking smells and are used in recirculating (non-vented) range hoods; they are not washable and must be replaced periodically. Some appliances use both types: a metal grease filter for grease capture and a charcoal cartridge for odors if the unit is set to recirculate air back into the kitchen.
my hood still smells or seems inefficient after cleaning the 6802A – what should I check?
If performance hasn’t improved after cleaning the grease filter, check for: blocked or restricted ducting (kinks, animal nests, or collapsed ducts), a clogged charcoal odor filter (if installed), failing blower motor or worn fan blades, incorrect fan speed selection, or improperly seated filters. also verify the exhaust is venting to the outdoors (if intended) and that external vent caps are not blocked. if these checks don’t solve it, have a qualified technician inspect the blower and electrical components.
Where can I buy a genuine Whirlpool 6802A filter and how do I verify it’s authentic?
Purchase genuine parts from the Whirlpool parts website, authorized Whirlpool dealers, or reputable appliance parts retailers. Verify authenticity by matching the part number (6802A) to the part listed for your appliance model, checking packaging for Whirlpool branding and part labels, and comparing the part’s fit and finish to OEM specifications. Keep receipts and check return policies; if you suspect a counterfeit or incorrect part, contact Whirlpool support for assistance.
