6802Aâ Whirlpool grease Filterâ is a removable grease-capturingâ elementâ used inâ kitchen ventilation⤠assemblies.â It is a passive filtration component-commonly â¤constructed from metal â˘mesh âor formed âbaffle material-designed âtoo âinterceptâ aerosolized âŁoil and food particulates entrained in cooking âŁvapors. As a field-replaceable part, its form âfactorâ and construction are chosen âtoâ balance⣠capture efficiency â˘against airflow â¤restriction and âto allow â˘periodic cleaning or â˘replacement without altering the ventilation⢠blower orâ ductwork.
Inside an appliance the âgreaseâ filter sits between⢠the cooktop or cooking⢠cavity â¤and⢠the exhaust blower or âŁrecirculation path, âŁand it directly interfaces with the fan housing, retainingâ clipsand in recirculating systems with downstream odor/charcoalâ filters. â˘Its primary roles are to reduce particulate loading on the blower, limit deposition in ducts and â¤heat-producing â˘components, â¤and reduce âŁthe ârisk of⣠grease-related ignition sources; because it affects static pressure âin⤠the ventilation system, its condition âinfluences âblower load, air flow rates,â and thermal sensor response. Improper fit,⤠damageor saturationâ of the⤠filter⤠can therefore âŁaffect exhaust performance⣠and component temperatures throughout âthe ventilation assembly.
In this article readers will find a technical description â˘of the filter’s function and âconstruction, guidance on verifying compatibility with âŁspecific Whirlpool models, diagnostic âindicators ofâ failing or saturated filters (reduced airflow, elevated motor temperature, odors, âvisible build-up), stepâbyâstep troubleshooting âand cleaning proceduresand practical replacement âŁconsiderations such as measuring âdimensions,⤠checking retention â¤hardware, material âselection (mesh⤠vs. baffle)and safe handling/disposal.Emphasis is placed on objective, serviceâlevel checks andâ replacement criteria that a technician, engineeror appliance owner can use to restore or maintain proper âŁventilation performance.âŁ

Functional Role and Performance âRequirements of the Grease Filter â˘Assembly
The 6802A⤠Whirlpool Grease âFilter serves as the primary âmechanical barrier âŁthat captures oil aerosols and⢠largeâ particulate matter from cooking exhaust before these contaminants reach the blower, ductworkor recirculation path. â¤In functional terms the assemblyâ must provide effective particle⤠capture while imposing minimal airflowâ resistance; excessive pressureâ drop âŁincreases blowerâ load and noiseâ and shortens motor life.⤠This part â˘is engineered â¤to match theâ original equipment dimensions and latchâ points so that sealing against âbypass is maintainedâ – proper fit⢠is âas⤠vital âas â˘the mesh material âŁfor maintaining designed airflow âand thermalâ performance.
- Material and construction: â¤washable metal⣠mesh or perforated panels to âretain grease⣠and allow âŁcleaning.
- Filtration vs. pressure drop: designed⢠to trap large aerosols without substantiallyâ reducing âairflow.
- Serviceability: removable â¤for routine cleaning or replacement⣠to restore â˘performance.
- Compatibility:⢠form, fitand âlatch/release features sized for â˘specificâ Whirlpool enclosure â¤models.
| Item | Description |
|---|---|
| Primary⤠function | Capture greaseâ aerosols and prevent buildup in âblower and ducts |
| Material | Washable metal⢠mesh orâ perforated metal⣠resistant to â¤routine âŁcleaning |
| Maintenance | Removable for cleaning; frequency â¤depends âon cookingâ intensity |
Performance requirements⢠for the âgrease filter â˘assembly emphasize sustainedâ capture efficiency,dimensional stability at elevated temperatures,and â¤resistanceâ to⤠corrosion from cleaning agentsâ and â¤cooking byproducts. A filter that deforms orâ corrodes willâ allow⤠bypass and reduce capture efficiency,⢠increasing fireâ risk âand âcontaminationâ of⢠downstream components;⣠conversely,â a⣠clean, intact filter preserves airflow and reduces energy⢠use. For technicians and owners, practical indicators of a failed â¤or undersizedâ filter include reduced exhaust performance, â¤increased kitchen smoke during high-heat cookingand visible greaseâ accumulation on⣠ductwork – replacing the filter âwith the âcorrect â˘6802A Whirlpool Grease Filter or restoring it by proper cleaning returns⤠the system to⤠its intended operating envelope.
How the 6802Aâ Whirlpool Grease âŁFilter Operates Within â˘the Range Hood âAirflow and filtration âSystem
The 6802A Whirlpoolâ Greaseâ Filter âis a⤠removable, washable â˘aluminum-mesh âŁelement that occupies the primary capture plane â¤of aâ range hood,⤠intercepting grease-laden â˘aerosols and larger particulates before they reachâ the fan âand⤠ductwork. In normal operation the filterâ uses âimpaction⢠and interception:â high-velocity intake air forces droplets and particles to strike⤠and coalesce on the mesh â˘strands, where âgravity and surface tension retain oil until cleaning. Correct seating and frame straightnessâ are critical â-â any gaps⤠at theâ frame âŁedges produce bypass flow that reduces â¤capture efficiency and â¤passes⣠more grease downstream toâ baffles, the⣠blower housingor the duct system.
- Material: âmulti-layer aluminum mesh – washable and corrosion resistant
- Primary mechanism: impaction/interception and coalescence
- Maintenance effect: increasing grease load âŁraises static pressure and lowers airflow
- Mounting: keyed frame or latchâ – must match hood cavity to prevent â˘bypass
Functionally, âthe filter shapesâ the hood’s effective pressure âdrop and â¤service intervals:⢠a clean⣠6802A presents low resistance and preservesâ designed capture velocity, while a saturated element increases blower load,⢠reduces capture at theâ grease â˘sourceand can accelerate carbon/charcoal replacement in combination systems.For troubleshooting, âŁinspect the filter âfor oil glaze, bent âframesor torn mesh when occupants report reduced capture â˘or louder âŁfan noise; if cleaning with a degreasing solution and drying does ânot âŁrestore permeability, â˘replace with aâ correctlyâ sized unit to avoid altered⢠airflow patterns.Verify compatibility by âŁmatching frame dimensions and latch locations to the hood â¤model before â˘installing a replacement to maintain intended performance.

|---|---|
| Part number | 6802A |
| Material | Multi-layer aluminum⤠mesh, removable andâ washable |

Common âFailure Modes and Diagnostic indicators for Grease Filterâ Degradation
Theâ 6802A Whirlpool Grease Filter is a mechanical filtration element intended to âcapture oil and grease â¤aerosols from range-hood exhaust before⣠they⣠enter the ductwork or⤠blower assembly. âTypical failure modes are media saturation (grease âloading that â˘reducesâ porosity), pleat collapse or frame deformation that⢠creates bypass pathsand media degradation from chemical attack⣠or⢠elevated temperatures. Technically,these failures manifest âasâ a rising pressure drop across the filter,increased downstream âŁfouling,and changes in âfan performance (higher motor current â˘orâ audible strain). compatibility considerations include âmatching⣠the filter’s pleat density, media âtype, frame dimensionsand mounting âarrangementâ to the specific Whirlpoolâ hood model or approved replacement â˘assemblies to âŁmaintain⢠designed capture⢠efficiency⤠and acceptable airflow (CFM)â loss under⤠load;â for example, heavy âfrying operations will shorten service lifeâ and require more⤠frequent replacement â¤compared with light-dutyâ domestic⤠cooking.
- Visibleâ glazed or âdarkenedâ surface with reduced pore openings – indicatesâ grease saturation.
- Oil dripping âor pooling on the downstream side -⣠indicates bypass or media breach.
- Persistentâ cooking odors or downstream duct coating – suggests⢠reduced capture efficiency or leakage.
- Measured increase â¤in static pressure or reduced airflow (CFM) at the hood – indicatesâ clogging or pleat collapse.
- Higher-than-normal fan motor current⤠or unusual vibration/noise -⢠indicates excessive load from a restricted filter.
| Item | Description |
|---|---|
| Pressure drop | A steady rise in measured ÎP across âthe filter correlates with media loading and⤠reduced airflow capacity. |
| Visual âclogging | Surface glazing, visible⤠layers of greaseor light-blocking pleatsâ indicate saturated media and â¤reduced capture efficiency. |
| Structural damage | Torn media, â¤bent frameor missing seals create bypass paths⤠that⤠lead to immediate⢠downstream contamination. |
Diagnostically, combine⣠visual inspection with objectiveâ measurements: perform a surface wipeâ test to confirm⣠oil saturation, use âŁa manometer to compare static pressure âupstreamâ andâ downstream⢠of the filterand record âfan motor currentâ to âdetect increased mechanical load. if static pressureâ climbs over baseline between scheduled maintenance âintervals or downstream grease deposits appear despite an apparently intact element, the filter media is likely saturated or â¤compromised âand should be replaced âwith a compatible 6802A⢠Whirlpool Grease Filter or an⢠equivalent that matches the original â˘specifications.⤠Practical troubleshooting â˘examples includeâ replacing the filter when â˘aâ 10-20% sustained drop in measured airflow⣠is accompanied by an increase⢠in âfan currentor when downstream duct âcleaning â˘reveals â˘greaseâ despite a â¤nominally installed filter, which points to bypassâ or media failure rather than âductwork alone.
Compatibility, âŁReplacement Considerations, Step-by-Step Installationâ and⤠Troubleshooting Protocols
The â6802A Whirlpool Grease Filter is âŁa removable metal mesh cartridge⢠that captures airborne grease aerosols beforeâ they reach the blower and ductwork, reducing buildup âon impellers⣠and âin the vent⢠system.â Its capture mechanism is primarily mechanical⤠interceptionâ and inertialâ impaction; as airflow velocity increases theâ filter â¤loading rate and pressure drop also increase. When selecting a replacement, match the frame footprint, clip/latch style andâ stack-up thicknessâ to the hood âŁmodel asâ small changes⤠in â¤thickness or mesh density can raise âstatic âpressure âŁand increase blower current draw, reducing fan efficiency and service life.
Installation and âtroubleshooting focus⤠on correct seating, integrity of⤠the âŁframeand the filter’s effect âon system airflow. Remove the filter using the hood’s release mechanism, inspect⣠for tears, crushed âedges or clogged pores, then⤠either clean with an alkaline degreaser and â˘high-pressure rinse or replace if âdeformation is⤠present. â˘After â˘reinstallation, verify that the filter seals flush against⢠the frame and â˘that latches engage; confirm proper function by observing restored airflow, absenceâ of grease smelland no increase in â˘motor current. If problems persist,check âfor warped filters,missing gaskets,looseâ fasteners,or unusual vibration âand âmeasure âblower current and static pressure to â˘isolateâ airflow restrictions âŁversus mechanical faults.
- Pre-install checks: dimensions, latch typeand frame thickness
- Common⤠symptoms of failure: reduced airflow, grease âodor, increased motor current, vibration
- Maintenance options: periodic wash â(residential light â˘use) or â˘replacement (heavy commercial use)
- Troubleshooting tools: âclamp ammeter for motor current, manometerâ for static pressure
