6802A Whirlpool Grease Filter is a removable grease-capture element used in Whirlpool kitchen ventilation products; it is indeed a physical filtration component-commonly constructed as a metal mesh or baffle insert-designed to trap oil and particulate generated during cooking. as a serviceable part, it mounts in the appliance’s exhaust or recirculation pathway and is sized and keyed to specific model housings, gaskets, and retention clips to maintain an effective seal and fit.
Inside the appliance system the grease filter protects downstream components by intercepting airborne grease and large particulates before they reach the blower, ductwork or a downstream charcoal (carbon) recirculation filter. By removing condensable oils and solids the filter reduces coating on fan blades, motor housings and heat-producing surfaces, which in turn affects airflow resistance (pressure drop), motor load, and fire/smoke risk. The filter therefore interacts mechanically with the blower/exhaust assembly and functionally with airflow and thermal-protection subsystems; its condition can influence noise, motor current draw and overall ventilation performance.
In this article readers will find practical,technical information about the 6802A Whirlpool Grease Filter,including its intended function,typical installation locations and model compatibility considerations,common failure or degradation symptoms (reduced airflow,greasy buildup,odors,increased motor load),basic troubleshooting steps for diagnosis and cleaning,and replacement considerations such as fitment tolerances,material condition and maintenance intervals.the goal is to provide the technical detail needed for accurate inspection, service decisions, and safe replacement without prescriptive brand recommendations.

Function and Role of the Grease Filter in Whirlpool Ventilation Systems
The 6802A Whirlpool Grease Filter acts as the primary mechanical barrier in range-hood and over-the-cooktop ventilation systems, intercepting airborne grease droplets and larger particulates before they reach the blower assembly and ductwork. Typical constructions are washable metal mesh or stamped baffle elements that use inertial separation and surface adhesion: heavier oil droplets impact and coalesce on the filter surfaces while air passes through, preserving designed airflow and protecting the motor and downstream components from grease buildup. Proper installation with correct dimensions, mounting tabs and orientation restores the hood’s designed pressure drop and capture efficiency; incorrect fit increases leakage, noise and risk of grease migration into the fan housing.
Functionally, a serviceable grease filter limits both fire hazard and mechanical wear by keeping grease out of the fan and exhaust path; a clogged or damaged filter increases static pressure, reduces capture efficiency and typically produces symptoms such as reduced airflow, stronger kitchen odors and visible grease deposits beyond the hood. Technicians and owners should inspect filters for deformation, perforations or saturation, clean metal filters per manufacturer guidance (many are compatible with warm-soapy-water cleaning or a dishwasher on a gentle cycle) and replace with an equivalent unit when cleaning no longer restores performance.For field replacement, confirm part geometry, latch type and airflow direction to ensure compatibility and to avoid accelerated fouling or undue stress on the ventilation motor.
- Material: metal mesh or stamped baffle (washable)
- Primary role: capture large droplets and reduce grease migration

How the 6802A Whirlpool Grease Filter Works Inside the Appliance: Filtration Principles and Flow Characteristics
The 6802A Whirlpool Grease Filter is a replaceable mesh/baffle element installed in the hood or internal plenum to intercept oil aerosols and condensable particulates produced by cooking. Its primary function is mechanical capture through a combination of inertial impaction and interception: larger droplets and fast-moving oil particles strike the filter surfaces and coalesce into films that drain away into a collection tray, while finer droplets are slowed and captured by successive mesh layers. The filter is engineered to match the hood’s designed airflow path and mounting footprint; using the correct 6802A part preserves intended capture efficiency, fit, and noise characteristics compared with non‑specified replacements.
Filtration behavior produces a progressive increase in pressure drop as grease loads build, which directly affects fan power and volumetric flow - this is why measured reductions in airflow or increased motor speed are common diagnostics for a clogged unit. in practical use, high-grease activities (pan-frying, wok cooking) accelerate loading and require more frequent cleaning than light baking or boiling; periodic removal, degreasing, and visual inspection restore original flow characteristics. Technicians should evaluate the filter for damaged welds, torn mesh, or warped frames as physical damage reduces capture efficiency and can create bypass paths that defeat the hood’s designed performance.
- Typical symptoms of a loaded or damaged filter: reduced exhaust flow, excessive smoke in the kitchen, oil pooling in the drip tray, or unusual fan noise.
- Recommended maintenance actions: remove, soak or wash in alkaline degreaser, inspect for integrity, and reinstall or replace if deformed or perforated.

Common Failure Symptoms and Diagnostic Tests for the 6802A Whirlpool Grease Filter
The 6802A Whirlpool Grease Filter is a metal mesh element designed to trap airborne grease and large particulates discharged by cooking appliances, protecting the blower, ducting, and downstream components. In normal operation the filter presents a predictable pressure drop and captures condensable oil and particulate layers on its surfaces; common compatibility is with Whirlpool range hoods and over‑the‑range units that accept this part number and similar mesh constructions. Failure of the filter typically alters airflow patterns, increases blower loading, and permits grease migration into the fan and ductwork, which accelerates wear and increases the likelihood of ignition if hot deposits accumulate.
- Progressive reduction in exhaust airflow or uneven ventilation across the hood.
- Visible grease saturation, darkening of mesh, or droplets forming and falling from the filter.
- Excessive blower noise, higher motor current draw, or frequent thermal cutouts of the fan motor.
- Corrosion, tears, deformation, or loss of retention features causing poor fit and bypass.
Diagnostic testing begins with a systematic visual and tactile inspection: remove the 6802A Whirlpool Grease Filter and check for thickness of accumulated deposits, rim damage, and gasket condition. Quantitative checks include an airflow or static pressure measurement upstream and downstream of the filter (use an anemometer or manometer) to determine pressure drop relative to a clean baseline, and a motor current measurement to detect increased loading when the filter is installed; a significant rise in ΔP or motor amperage indicates the filter is restricting flow and should be cleaned or replaced. Practical maintenance steps include photographing and weighing the filter before/after cleaning to track deposit mass, verifying correct seating and retention to prevent bypass, and replacing the element if mesh is clogged, warped, perforated, or if cleaning does not restore original pressure characteristics.

Compatibility, Replacement Considerations, and Step-by-Step Installation for the 6802A Whirlpool Grease Filter
The 6802A Whirlpool Grease Filter is a metal mesh grease filter designed to trap airborne oil and particulate that would or else accumulate in the exhaust path of range hoods and over‑the‑range microwave ventilation systems.Functionally it uses impingement and surface capture on woven or perforated metal to remove droplets and aerosols from the airflow; this reduces downstream fouling of blowers and ductwork and improves heat transfer away from the cooking surface. Compatibility depends on physical dimensions, mounting tab layout, and frame thickness rather than brand alone, so technicians should verify slot spacing, overall length/width, and the location of any retention clips before assuming interchangeability with other filters. Practical examples: a filter with bent tabs or a frame thicker than the housing will not seat correctly; conversely, a properly sized stainless mesh element can frequently enough be cleaned and returned to service, whereas damaged mesh or corroded frames require replacement to restore capture efficiency and airflow balance.
Replacement and installation are straightforward but must respect the mechanical interface and airflow integrity. Remove power to the appliance light and fan if accessible, release the retaining clip or slide the latch to extract the old filter, inspect the housing for grease build‑up or damage, and confirm the new filter’s tab alignment and orientation match the retention points before insertion. Insert the new filter so the mesh faces the incoming airflow path as indicated by the housing direction,engage the retaining mechanism,and run the fan briefly while listening for vibration or rattle that indicates poor seating; check that airflow is not considerably reduced compared with expected performance. If the filter is intended to be reusable, document cleaning frequency based on cooking load (for example, heavy frying may require monthly cleaning versus quarterly for light use) and replace immediately if the mesh has holes, persistent oil saturation, or frame deformation that prevents a tight seal.
- Pre‑install checklist: verify dimensions, check retaining clip location, confirm mesh condition, and ensure absence of frame distortion.
- Rapid installation steps: remove old filter → inspect housing → align tabs → insert filter → secure latch → test fan and listen for rattles.
- Maintenance tip: clean washable metal filters with degreasing solution and inspect for holes; replace if structural integrity is compromised.

Q&A
What is the Whirlpool 6802A grease filter?
the 6802A is a reusable grease filter designed for Whirlpool range hoods and over‑the‑range microwaves. It is a metal (usually aluminum) mesh filter that traps grease and large particles in the vent stream so they don’t coat the blower and ductwork.
How do I know if the 6802A filter fits my appliance?
Verify fit by checking your appliance model number and the parts list in the owner’s manual or on Whirlpool’s official parts lookup. You can also remove the existing filter and look for a part number stamped on the frame.If you can’t find a marking, match the physical size and mounting tabs or consult Whirlpool customer support or an authorized parts dealer with your appliance model number.
How do I remove and install the 6802A grease filter?
Most installations use a simple latch or push‑tab system. To remove: turn off the vent light/fan, release the retaining latch or depress the access tab, and slide or tilt the filter out of its frame. To install: position the filter so the mounting tabs line up with the slots, engage the tabs, and snap the retaining latch back into place.Because mounting details differ by model, follow steps shown in your appliance manual if available.
Is the 6802A grease filter dishwasher safe?
Yes – the metal mesh 6802A is generally dishwasher safe, and many owners place it on the top rack with a normal detergent cycle. Though, repeated dishwasher exposure and high‑heat drying can shorten the filter’s life. Hand washing with hot water and a degreasing cleaner is gentler and recommended if you want to prolong service life.
How frequently enough should I clean or replace the 6802A filter?
Clean the filter at least once a month under normal cooking conditions; clean more often if you do a lot of frying or grease‑heavy cooking. Replace the filter when it is indeed bent, torn, the mesh is permanently clogged, or the frame is damaged-typically every 1-2 years depending on use and maintenance.
what is the correct way to clean the 6802A grease filter?
Recommended cleaning: remove the filter, soak it in hot water with a degreasing dish soap or a solution of hot water and baking soda for 10-20 minutes, scrub gently with a soft brush, rinse thoroughly, and allow it to dry completely before reinstalling. If using a dishwasher, place it on the top rack and avoid high‑heat drying cycles.
My 6802A filter rattles or won’t stay in place – what should I check?
First, ensure you have the correct part for your model. inspect the filter’s mounting tabs and the hood’s retainer/latch for bending or broken pieces. Clean any grease build‑up on the latch area so the filter seats fully.If tabs are bent, carefully bend them back into shape or replace the filter. Retainer springs or clips may also need replacement if they’re worn.
Where can I buy an OEM 6802A filter and are aftermarket filters acceptable?
You can buy OEM 6802A filters from the Whirlpool Parts website, authorized Whirlpool dealers, and many appliance parts retailers. Aftermarket filters are available and might potentially be less expensive, but check dimensions, mounting style, and material (aluminum mesh vs.other types) to ensure a proper fit and performance. OEM parts preserve factory fit and warranty alignment more reliably than some aftermarket options.
