6802A Whirlpool Grease Filter is a replaceable filtration element used in kitchen ventilation assemblies, typically found in range hoods and over‑the‑range microwave/ventilation units. It is indeed a passive grease capture device-commonly constructed as a metal mesh or baffle element-that traps oil and particulate aerosols produced by cooking before they reach the blower, ductwork, or recirculating components. Its construction and fitment are designed to balance capture efficiency with acceptable airflow resistance for the appliance’s rated CFM.
Inside the appliance the grease filter sits upstream of the blower and, in recirculating configurations, ahead of any charcoal or catalytic odor filters. By removing grease-laden aerosols it reduces deposition on the fan, motor, heating elements, light lenses, and duct surfaces, and thus affects motor load, heat transfer, noise characteristics, and long‑term reliability of the ventilation system. The filter’s airflow resistance (pressure drop) and loading characteristics directly influence overall ventilation performance and maintenance intervals, so its condition and correct installation are relevant to system diagnostics and safe operation.
In this article you will learn how the 6802A grease filter functions within the ventilation system, how to determine compatibility and correct fitment, common failure and degradation symptoms (for example, visible grease buildup, reduced airflow, increased noise, odors, or motor overheating), and practical troubleshooting steps to isolate filter‑related problems. You will also find guidance on cleaning versus replacement criteria, material and mounting considerations, and safety and service practices a technician or appliance owner should follow when servicing or replacing the filter.

Function and Role of the 6802A Whirlpool Grease Filter in Range Hood Exhaust Systems
The 6802A Whirlpool Grease Filter functions as a passive mechanical barrier in a range hood exhaust system that captures aerosolized oil and grease before they reach the blower, ductwork, and external vent. As cooking vapors pass through the filter media, grease droplets coalesce on the filter surface and drain into a designated collection area or tray; this reduces particulate loading on downstream components and lowers the long-term buildup that increases fire risk and duct corrosion. The filter introduces a small,predictable pressure drop in normal condition; tho,accumulated grease considerably raises that pressure drop,degrading exhaust capacity and increasing fan noise until the filter is cleaned or replaced.
- Primary role: trap and coalesce grease aerosols to protect blower and ducts.
- Behavior: washable, passive element that accumulates grease and requires periodic cleaning.
- Performance impact: increases pressure drop when fouled, reducing airflow efficiency.
- Limitations: does not remove odors or gaseous contaminants (carbon/charcoal filters are separate).
| Item | description |
|---|---|
| Typical construction | Metal mesh or baffle elements designed for oil capture and repeated washing |
| Maintenance interval | Depends on cooking activity; common practice is monthly for heavy frying, 1-3 months for typical home use |
| Compatibility check | Verify part number, dimensions, and retention clips against yoru hood model before replacement |
For technicians and appliance owners, practical handling of the 6802A Whirlpool grease Filter means verifying fitment to the hood model and inspecting the filter during routine maintenance. Symptoms that indicate service are reduced airflow, increased blower noise, or visible grease saturation; cleaning is usually accomplished with a degreasing detergent or a dishwasher cycle if the manufacturer allows, and worn or damaged filters should be replaced to restore designed airflow and protect the exhaust system. When integrating or specifying this filter in a repair or upgrade, confirm that the filter addresses grease management but pair it with appropriate odor or charcoal filters if air purification beyond particulate capture is required.
How the 6802A Whirlpool Grease Filter Works Inside the Appliance: Filtration Mechanics, Airflow Path, and Thermal Limits
The 6802A Whirlpool Grease Filter is a passive mechanical element located in the appliance exhaust path that separates oil-laden aerosols from the airstream by changing flow direction and presenting metal surfaces for impaction and coalescence. Air and vapor drawn from the cooktop accelerate through the filter media; larger droplets and oily particulates cannot follow the rapid flow turns and strike the mesh or baffle surfaces, where they accumulate and run back into the drip channel. Variants of this filter use layered metal mesh or baffle plates to balance capture efficiency against pressure drop, so correct fitment to the hood or over‑the‑range microwave slot and seal engagement with retaining clips is necessary to preserve the designed airflow characteristics and prevent bypass leakage.
- Primary capture: inertial impaction and coalescence on metal surfaces.
- Service behavior: grease build-up increases pressure drop and reduces exhaust flow; cleaning restores performance.
- Compatibility: fits models specifying 6802A geometry; verify retainers and clearance before replacement.
- Thermal constraint: designed for normal cooking vapors-do not expose to open flame or broiler-level direct heat.
In service, a clogged or deformed 6802A will raise backpressure on the blower motor, frequently enough seen as reduced airflow, higher noise, or earlier motor thermal trips; technicians should measure airflow or static pressure when diagnosing performance loss. Cleaning is typically mechanical degreasing with detergent and hot water or a dishwasher-safe cycle for metal filters; avoid high-temperature oven cleaning or flame-based methods that can warp the media and compromise sealing. replace the filter if there is physical distortion, torn mesh, or persistent odor after cleaning, since a damaged filter cannot reestablish the original flow path and will lower capture efficiency and increase load on the exhaust fan.
| Item | Description |
|---|---|
| Primary mechanism | Inertial impaction and coalescence on mesh or baffles |
| Typical maintenance | Degrease every 1-3 months depending on cooking frequency |
| Thermal exposure | Rated for hot cooking vapors; not for direct flame or broiler contact |
Common Failure symptoms and Diagnostic Indicators of grease filter Clogging or Structural Degradation
The 6802A Whirlpool Grease Filter functions as a coalescing and mechanical capture element in kitchen exhaust assemblies, intercepting aerosolized oil and large particulate generated during cooking. As the filter loads with grease and particulate,its effective open area decreases and the pressure drop across the element rises,which reduces volumetric airflow and raises the blower motor’s operating temperature and current draw. Structural degradation - torn mesh, detached frame, or sagging pleats – produces flow bypass paths that allow unfiltered grease to reach downstream ducting and fans, increasing fouling and fire risk while degrading system performance. Technicians should consider both loading (clogging) and mechanical integrity when diagnosing deteriorated performance,and verify that the installed part matches the appliance’s design tolerances to preserve seal and airflow characteristics.
- Progressive airflow reduction: longer smoke-clearing times, weaker capture at the hood edge, or measured reduction in flow rate compared with baseline.
- Increased blower current or temperature: elevated amperage or hotter motor housing indicating higher effort to overcome a clogged filter.
- Visible grease saturation or dripping: heavy, darkened deposits, pooled oil, or wet areas on the filter surface indicating loss of capture capacity.
- Physical damage and bypass: perforations, torn mesh, warped frames, or incomplete seating that permit unfiltered flow around the media.
- Odor, smoking, or downstream contamination: persistent odors, smoke stains in ducts, or grease on fan blades and motor housings.
Diagnostic checks combine simple visual and tactile inspection with basic measurements: compare current airflow or static pressure across the filter to a known good baseline, monitor blower current for rises under similar load conditions, and perform a close inspection for frame distortion or media failure.For practical example, a technician who records an increase in static pressure and concurrent rise in blower current should remove the filter to confirm grease loading and inspect for mesh tears; if the element fits loosely or shows frame damage, replacing it with the correct OEM unit restores designed sealing and flow paths. Regular maintenance intervals and documented pre-/post-repair measurements help distinguish a saturated but intact 6802A filter from one that has experienced irreversible structural degradation and requires replacement.
| Item | Description |
|---|---|
| pressure/airflow | measured increase in ΔP or drop in CFM relative to baseline, indicating media loading and reduced open area. |
| Visual condition | Darkened, wet, or dripping media and any tears, collapsed pleats, or warped frame that allow bypass. |
| Electrical/motor response | Higher blower current or temperature and increased noise, consistent with elevated system resistance from clogging. |
Replacement Considerations and Installation Procedure for the 6802A Whirlpool Grease Filter, including Seal and Fastener Verification
The 6802A Whirlpool Grease Filter is a baffle-style capture device designed to remove grease particles from the airflow path in select Whirlpool range hoods and over‑the‑range microwaves. Its function is based on directional change and impingement: airborne grease droplets strike the baffles, coalesce into larger droplets and drain away from the airflow, reducing downstream contamination of the blower and ductwork. Over time the filter will accumulate deposits, deform, or lose the integrity of its sealing surfaces; these changes reduce capture efficiency and increase pressure drop, so technicians should assess physical condition, dimensional fit, and contact surfaces before reinstalling or replacing the unit.
- Power down the appliance and remove the filter by the manufacturer‑specified release method (slide, rotate, or unclip) to avoid damaging retainers.
- Inspect the perimeter seal for compression set, cuts, or hardening; replace seals made of EPDM or silicone if they no longer maintain continuous contact.
- Examine fasteners and retention clips for corrosion, stripped threads, or spring loss; replace any clip or screw that does not secure the filter without play.
- Confirm correct seating and orientation of the filter so baffle drains align with the collection trough and airflow is unobstructed; reattach retainers and verify engagement.
- Perform a functional check at low fan speed to detect vibration, rattle, or bypass leaks; if leakage is suspected, use a visible smoke source or airflow measurement to confirm seal integrity.
| Item | Description |
|---|---|
| Seal material | Typically EPDM or silicone; replace if brittle or compressed |
| Fastener type | Spring clips or small machine screws (#6-#8) depending on appliance trim |
| Recommended torque | 8-12 in‑lb for typical retaining screws; follow appliance service manual when available |
Q&A
What is the 6802A Whirlpool grease filter and what does it do?
The 6802A is a grease-capture filter used in whirlpool range hoods and some over‑the‑range microwave exhaust systems. Its job is to trap airborne grease and large particles produced during cooking so grease does not enter the ductwork or motor housing. Many 6802A-style filters are reusable aluminum mesh filters designed to be cleaned rather than thrown away.
How do I know if the 6802A is the correct filter for my appliance?
Check the appliance’s user manual or the label inside the hood/microwave for the parts list and compatible part numbers. You can also remove the existing filter and read the part number stamped on it. If you’re unsure, enter your appliance model number on the Whirlpool parts website or contact an authorized Whirlpool parts dealer to confirm compatibility.
how do I remove and install the 6802A filter?
Typically you unlock or depress a small latch or tab at the front of the grille, then tilt and slide the filter out of its frame. Installation is the reverse: align the filter’s tabs with the slots, push it into position, and re-engage the latch until it clicks. Always consult your appliance manual for the exact removal/installation steps and make sure the hood is powered off before working on the filter.
How frequently enough should I clean or replace the 6802A filter?
Frequency depends on cooking habits. For moderate home use, clean the mesh filter every 1-3 months; for heavy frying or commercial‑style cooking, clean monthly or more often. Replace the filter if it is indeed bent, torn, has broken tabs, or cannot be cleaned to remove heavy baked‑on grease. Even with regular cleaning, consider replacement every 1-3 years if performance degrades.
What is the safest and most effective way to clean a 6802A mesh grease filter?
for aluminum mesh filters: soak the filter in hot water with a degreasing dish soap or a solution of hot water and a small amount of baking soda for 10-20 minutes, then gently scrub with a soft brush, rinse thoroughly, and let dry fully before reinstalling.Many mesh filters are also dishwasher‑safe (top rack), but repeated dishwasher cycles can dull or discolor the finish-hand washing is recommended for best results. If your filter contains a charcoal or carbon insert, do not wash it; those are replaceable cartridges.
Can I use a non‑OEM or universal filter instead of the Whirlpool 6802A?
You can often use a high‑quality aftermarket or universal filter with the same dimensions and mounting style,but OEM filters guarantee fit and material compatibility. If using a non‑OEM filter, verify exact dimensions, tab orientation, and mounting method to ensure it fits correctly and does not interfere with the fan or lights. Avoid replacing a washable mesh filter with a non‑washable carbon type unless your unit is designed for a recirculation mode with charcoal inserts.
My hood still smells or ventilation seems weak after cleaning the filter-what should I check?
If odors or poor airflow persist after a clean filter, check for: clogged ductwork or grease buildup in the duct, a failing blower motor or fan, improperly installed filter (gaps), or a saturated charcoal filter if your unit uses recirculation cartridges. Also confirm the exhaust damper is opening (for ducted installations). If you cannot locate the issue, contact a qualified technician to inspect the blower and ducting.
Where can I buy a replacement 6802A filter and how should I dispose of the old one?
Buy replacements from Whirlpool authorized parts dealers, the Whirlpool parts website, appliance parts stores, or reputable online retailers. Always verify the part number against your appliance model. For disposal, aluminum mesh filters can usually be recycled with other scrap metal if cleaned of grease; if contaminated with heavy grease, follow local waste disposal guidelines. Carbon/charcoal filters should be disposed of according to local regulations for household waste if not recyclable.
