The 6802A Whirlpool Grease Filter is a removable grease-capture element used in kitchen ventilation assemblies. It is a mechanical filtration component-typically a metal mesh or baffle-type insert-designed to intercept oil and particulate-laden cooking vapors before they enter the blower, ductwork, or recirculation path of a Whirlpool range hood or over-the-range microwave.
Inside the appliance, the grease filter sits between the cooking zone and the exhaust system and directly interacts with the exhaust blower, duct or recirculation housing, and any downstream charcoal or odor-absorbing filters. By collecting condensable grease and larger particulates, the filter protects the blower motor, duct surfaces, fan housing, sensors and control elements from fouling, limits fire and odour risks, and helps maintain designed airflow and static-pressure characteristics.A poorly fitting or clogged filter increases fan load, reduces throughput, and can accelerate component wear.
In this article you will find technical details on the 6802A’s intended function and typical materials and form factors, guidance on compatibility and how to identify the correct replacement, common failure and performance symptoms (reduced airflow, increased noise, visible grease buildup, or odor), basic troubleshooting and inspection steps, recommended cleaning and maintenance practices, and practical replacement considerations such as sizing, mounting interfaces, and safety precautions to observe during service.

Function and Role of the Grease Filter in Whirlpool Range Hood Airflow and Fire Safety
The 6802A Whirlpool Grease Filter functions as a primary mechanical barrier that removes oil droplets and grease-laden aerosols from the exhaust stream before they reach the blower and ductwork. Its geometry and media create zones of inertial impaction and interception where higher-mass droplets coalesce on metal surfaces and drain into a collection cavity; this prevents progressive deposition downstream that would otherwise increase static pressure,reduce volumetric flow (CFM),and load the motor. By keeping the blower and ducts cleaner, the filter preserves designed airflow patterns and minimizes localized heat buildup at the hood inlet-both effects that directly influence capture efficiency and operational noise as the filter loads with grease.
- Typical maintenance: clean or replace on a schedule matched to cooking intensity (light home use: roughly every 1-3 months; frequent frying or commercial use: weekly to biweekly).
- Clogging symptoms: measurable drop in suction (lower CFM), audible fan strain, visible grease film, or persistent odors.
- Installation/compatibility checks: verify part number,dimensions,latch orientation,and sealing surfaces to ensure the filter seats correctly and does not create bypass leakage.
- Fire-safety role: the filter reduces combustible fuel in ducts; though, accumulated grease still poses an ignition hazard if allowed to build up or if the filter becomes warped or damaged.
For technicians and owners, the practical behavior of the 6802A under load is predictable: as grease accumulates the pressure drop across the element rises, which can be confirmed with simple airflow or static-pressure measurements and serves as a maintenance trigger.Replacing or refurbishing the filter with matching geometry and intact sealing surfaces restores original airflow and reduces the risk of heat concentration and ignition in the hood assembly; conversely, fitting an incorrect or poorly seated element can create bypass flow paths, accelerate duct deposition, and undermine both performance and fire-safety design margins.
How the 6802A Whirlpool Grease Filter Works Inside the Appliance: Filtration Mechanism and Airflow Path
The 6802A Whirlpool Grease filter is a replaceable grease-capture element used in Whirlpool range hoods and over‑the‑range microwave vents to remove oil and condensed cooking aerosols from the exhaust stream.Internally the filter relies on mechanical interception and inertial impaction: as hot, grease‑laden air accelerates through the hood inlet it changes direction and is forced through a series of mesh or baffle layers where heavier droplets impact on metal surfaces and coalesce into rivulets that drain into a collection trough. This design reduces oil migration into the fan housing and ductwork while producing a predictable pressure drop that technicians can account for when measuring blower performance or diagnosing reduced airflow.
Airflow follows a defined path: intake → pre‑separator (if present) → the 6802A filter media → blower housing → discharge or recirculation path. The filter captures particles and droplets across a range of sizes, but it is not a particulate HEPA device; very fine smoke and gaseous byproducts pass to the blower and any downstream charcoal or catalytic modules. Practical implications include higher motor load and increased noise if the filter is clogged,and visible grease buildup on the mesh that indicates cleaning or replacement is needed. for compatibility, the 6802A is specified for particular Whirlpool mounting geometries and should be matched to model service literature; replacing it with the correct OEM part preserves designed airflow characteristics and mounting clearances.
- Material: washable metal mesh or multi‑layer baffle construction for coalescing grease.
- Capture mechanism: inertial impaction and surface adhesion; drains to a collection channel.
- Maintenance: regular cleaning restores airflow; clogged filters increase blower current and reduce extraction.
- Compatibility: OEM fit for designated Whirlpool models-confirm part number and mounting type before replacement.

Common Failure Symptoms and Performance Indicators of a Degraded Grease Filter
The 6802A Whirlpool Grease Filter is a removable metal mesh/baffle-style capture element designed to intercept airborne grease and large particulates before they reach the blower, ductwork, and internal electronics of a range hood or over-the-range microwave. In normal operation the filter presents a low-resistance path for exhaust air while coalescing and trapping oil droplets; compatibility is determined by the filter’s nominal dimensions and mounting tabs, so technicians should verify fit against the appliance model number rather then assuming universal interchangeability. In kitchens with frequent high-temperature frying or prolonged oil vapor production the filter media will load faster, reducing effective porosity and increasing deposition downstream; routine inspection and either cleaning or replacement maintain designed motor load, thermal performance, and fire-mitigation behavior of the appliance.
- Visible darkening/saturation of the mesh or oil pooling on the filter surface.
- Reduced exhaust airflow and longer time to clear smoke or steam from the cooking area.
- Accumulation of grease beyond the filter (on fan blades, interior housing, or duct surfaces).
- Intermittent or continuous odors that cleaning of the cooking surface does not remove.
- Unusual fan noise or increased motor temperature, indicating higher mechanical load.
Technicians commonly use the symptoms above as practical performance indicators: visible oil saturation signals the need for cleaning or replacement,while persistent odors or grease downstream indicate bypass or media failure and often require replacement of the 6802A Whirlpool Grease Filter and inspection of mounting seals. For diagnostic clarity, check airflow with a simple smoke test or an anemometer at the hood inlet and visually inspect the filter frame for warping or damaged seals that allow unfiltered flow. The table below summarizes typical symptoms and the most likely corrective action for swift troubleshooting.
| Item | Description |
|---|---|
| Reduced airflow | Clogged or oil-saturated media - clean with degreaser or replace filter; verify duct restrictions. |
| Grease beyond filter | Damaged frame or poor sealing – replace filter and repair/adjust mounting to stop bypass. |
Replacement Considerations, Model Compatibility and installation Procedure for the 6802A Whirlpool Grease Filter
The 6802A Whirlpool Grease Filter is a removable mesh filter designed to trap airborne grease and larger particulates upstream of the blower and ductwork in range hoods and over‑the‑range microwave exhaust systems. Constructed from layered metal mesh with a frame sized to specific Whirlpool housings, the filter reduces grease deposition on motor components and duct interiors but also introduces a measurable pressure drop that can alter fan performance if the media is heavily loaded. Technicians should consider filter depth, frame profile, and retention clip locations when assessing airflow effects; for example, a deeply saturated mesh in a high‑heat, frying‑intensive kitchen will raise static pressure and reduce exhaust velocity more than in homes with predominantly dry‑cook methods.
Before ordering or installing a replacement, confirm appliance model and part cross‑references rather than assuming universal fit, since variations in flange size and latch type affect compatibility. Service procedure typically follows this sequence: disconnect power, release retaining clips or slide the old filter out, inspect the housing for grease buildup or damaged seals, fit the new filter ensuring the frame seats evenly and latches engage, then restore power and run the fan to verify there is no vibration or obstruction. perform a brief airflow check at multiple speeds and visually inspect for gaps that could bypass the filter; for heavy use environments consider a scheduled inspection or replacement every 3-6 months and interim washings for reusable metal mesh elements.
- Verify appliance model number and part cross‑reference before purchase.
- Power off and remove retaining hardware before filter extraction.
- Inspect housing and seals; clean or repair before new installation.
- Seat filter fully and confirm clips/latches prevent movement and bypass.
- Test fan operation and airflow at multiple speeds after installation.

Q&A
What is the Whirlpool 6802A grease filter and where is it used?
The 6802A is an OEM grease filter used in some Whirlpool/KitchenAid/Maytag range hoods and over-the-range microwave exhausts. It is indeed a metal mesh filter that captures grease and large particles from the cooktop exhaust before they reach the blower or ductwork. Always confirm fit by checking your appliance model number against the part listing or owner’s manual.
How do I remove and reinstall the 6802A grease filter?
Most mesh grease filters have a spring clip, latch or small handle. Turn off the hood fan and lights, locate the filter frame, release the clip or press the latch, and pull the filter down and out. To reinstall, align the filter’s tabs into the slots or frame, push it into place untill the latch engages. If the filter feels loose or doesn’t seat, check for bent tabs or obstruction and realign before forcing it.
Can I clean the 6802A grease filter in the dishwasher?
yes – the metal mesh 6802A filter is generally dishwasher-safe. Place it on the top rack, avoid crowding, and use a normal cycle with a degreasing detergent. Be aware dishwasher detergents and high-heat drying can cause discoloration over time. For heavy grease, a manual soak in hot water with a degreasing cleaner or baking soda and dish soap is frequently enough more effective.
How often should the 6802A grease filter be cleaned or replaced?
Cleaning frequency depends on cooking habits: clean the mesh filter every 1-3 months for typical household use, more often with heavy frying. Replace the filter only if it is torn, excessively bent, or the mesh is clogged beyond cleaning. Charcoal (odor) filters, if present in your unit, are not washable and typically require replacement every 3-6 months.
What are signs the 6802A grease filter needs attention or replacement?
Signs include noticeably reduced exhaust airflow, persistent cooking odors, visible tears or holes in the mesh, warped frame that prevents a proper seal, or grease that won’t come clean after soaking. Any of these indicate cleaning or replacement is necesary to protect the blower and ductwork.
Is the 6802A the same as a charcoal odor filter?
No. The 6802A is a washable metal mesh grease filter that traps grease and particulates. charcoal (carbon) odor filters are separate, non-washable cartridges used in recirculating (non-ducted) installations to remove odors. Check your hood’s configuration and parts list to know which filters you need.
How do I make sure I order the correct replacement 6802A filter?
Confirm the appliance model number (found on the tag inside the hood or oven cabinet) and search OEM parts listings or Whirlpool’s parts site for part number 6802A. If uncertain, provide the appliance model number to an authorized parts dealer or Whirlpool customer service to verify compatibility. Do not rely on physical measurements alone, as latch and tab locations vary.
Any special cleaning tips or safety precautions for the 6802A?
Turn off the hood before servicing. For cleaning, soak the filter in hot water with a grease-cutting detergent or use a commercial degreaser, then gently scrub with a non-abrasive brush and rinse thoroughly. Avoid steel wool or hard scrapers that can damage the mesh. Allow the filter to dry fully before reinstalling. Dispose of damaged filters per local recycling/disposal rules for metal parts.
