Function âŁand Roleâ of the âŁAluminum Grease filter â˘in Airflow⤠control âand Fire⣠Safety
The W10113040A â˘Whirlpool Aluminum Grease Filter is a perforated, multi-layer â¤aluminum mesh⢠element that sits âŁdirectly in âthe⤠airflow path ofâ a hood or overâtheârange ventilationâ assembly to intercept oil droplets, condensates⣠and âlarger particulate⤠matter. By capturing liquid âand semi-solid âgreaseâ upstream⤠of âthe fan and ductwork,â the filter reduces deposition on the blower, heat exchangersâ and internal surfaces âŁthat can both impede airflow and create a âcombustible fuel layer. The â˘filter’s aluminum construction â¤provides dimensional stability at elevated temperatures and resists corrosion from âtypical kitchen detergents; the physical âdesign and retention points are matched â˘to â¤specific Whirlpool housings so correct â˘seating âand orientation⣠are essential âŁfor âŁintended airflow control and âŁto maintain manufacturer-rated âclearance to heat-producing elements.
Accumulated grease increases âŁthe filter’s pressure âŁdrop andâ lowers volumetric flow rate, which â¤can lead to higherâ motor load, âincreased noise andâ reduced capture efficiency forâ combustion byproducts and cooking aerosols. âŁRegular inspection and cleaning restore permeability and help maintain the designed ventilation performance: remove the filter, check⢠forâ rips or⢠permanent deformation that woudl necessitate âŁreplacement, degrease withâ hotâ water and a suitable solvent or âuse a âŁdishwasher cycle where permittedand â¤fully dry âbefore reinstalling. In field service or installations, âaâ damaged or â˘illâfitting âfilter â˘should be replaced rather thanâ patched, because â˘gaps or bypass paths compromise both airflow control⤠and theâ filter’s role in minimizing grease accumulation that could contribute to ignition in⢠a⤠fault âor highâheat scenario.
- Maintenance: remove, inspect,⤠degrease, âdry, âandâ reseat; replace if torn, pinholedor warped.
- Behavior: clogging⢠raises static⢠pressure âŁand âŁreduces capture⣠efficiency and motorâ life.
- Compatibility: designed to fit designated Whirlpool ventilation assemblies; verify fit before âreuse.

How the W10113040A Whirlpool Aluminum Grease Filter âOperates âWithin the âAppliance Exhaust assembly
The W10113040A â¤Whirlpool Aluminum Grease Filter is an⤠aluminum mesh capture element installed in the â¤intake side â¤of âthe âapplianceâ exhaustâ assembly to collect oil âand grease aerosols generated âŁduring cooking. As exhaust air passes through the layered mesh, grease droplets are removed by inertial impaction⤠and surface adhesion to the filaments;â this prevents âoil from accumulating on the⤠blower wheel,â motor âŁhousing, âŁand downstream ductworkand reduces âŁlocal combustion risk. The filter is a⢠serviceable, removable insert thatâ seats inâ a dedicated frame or grille so that the air stream is forced throughâ the mesh rather âthan bypassing the element.
performanceâ of the W10113040A Whirlpool Aluminumâ Grease Filter is defined by âŁcapture efficiency versus pressure loss: as grease loads on theâ mesh its pressure drop â¤increases andâ available airflow âŁto the exhaust fan decreases,⤠so âroutine⤠cleaning restores original airflow characteristics.Technicians should verify âmechanical fit (tab locations and âthickness)â whenâ sourcingâ replacements, âand applianceâ owners⣠should âinspectâ visually afterâ frequent high-grease â¤cooking (e.g., â˘pan-fryingâ or wok use). Typical maintenance⤠options⢠include detergent â¤soak and manual scrubbing âorâ useâ of⤠a dishwasher per appliance guidance; after âŁcleaning, âconfirm correct orientation and secure⤠latching to avoid vibration or bypassing the filter during⢠operation.

Common Failure Symptoms⣠and Diagnosticâ Indicators of W10113040A Filter Degradation
W10113040A Whirlpool Aluminum â¤Grease Filter â is an â¤aluminumâ meshâ capture element designed to trap⢠liquid and particulate âgrease âupstream â˘of the blower âand ductwork âinâ Whirlpool⢠range hoods. âItsâ primary âŁfunctionâ is âto coalesce aerosolized oil droplets â˘into larger âŁfilms that run down the mesh into a collectionâ channel, while allowing theâ exhaust airstream to⤠pass; â˘theâ filter’s effective porosity âŁand frame integrity determine pressure dropâ and capture⣠efficiency. Typical â¤failure modes are mesh glazing (oil build-up that closes⤠pore paths), mechanical deformation of the⢠frame or retaining tabs, corrosion/perforation of âthe aluminum âlayersand detached mesh âlayers – any of which increases⣠airflow resistance, permits grease migration âpast the filteror creates bypass âpaths that reduce overall system performance.
- Reduced exhaust flow or lower measured âairflow at âthe hood outlet – indicates increased pressure drop⢠across the filter⣠(use an anemometer⢠or compare⣠with baseline values).
- Persistent cooking âodors or visible smoke in the kitchen while fan is âoperating – suggests bypass orâ loss âof capture efficiency from⣠glazing or tears.
- Visible oil film, dark glazing, âŁor clogged mesh whenâ removed for inspection â-⤠cleaning restores function if mesh andâ frame are undamaged.
- Grease deposits inside blower housingâ or ductwork – a sign that the filter hasâ failed to âcapture particulates and requiresâ replacement.
- Rattling, âvibration,â or unusual â˘motor heatâ – can result from a distorted filter causing impingement⣠or âincreased motor load from⣠restricted flow.
| Item | Description |
|---|---|
| Visual inspection | look for oil glazing,â tears, perforationsand bent retaining tabs; cleanable grime âvs irreversible damage differentiatesâ service vs⤠replacement. |
| Airflow/pressure check | Measure flow at the hood â˘or static pressure acrossâ theâ filter; âsignificant deviation from âexpected values indicatesâ excessive resistance. |
| Post-clean performance | If a⢠thorough cleaning (degreaser and hot water) does not restore airflow⢠and capture, the⣠filter’s mesh âor frame has likely degraded and should beâ replaced. |
For practicalâ diagnostics, remove â¤the filter and perform a staged assessment: visual and tactile examination for âstructural damage,⤠a light âtest to â¤locate opaque/glazed⤠regions, then a controlled cleaning and re-measurement of airflow and noise. In installations â¤with heavy âŁfrying or commercial-style⣠use, âschedule⢠more frequent inspections⤠andâ document baseline airflow so deviations are quantifiable.â when replacement is required, match â¤theâ filter by physical âŁdimensions andâ retention method to avoid âbypass;â an â˘improperly sized element will not â˘restore designed capture performance and can âaccelerate contamination⣠of the âblower and ductwork.
Compatibility, Replacement Considerations, Installation Procedureand Troubleshooting â¤for Affected Whirlpool⤠Models
The W10113040A Whirlpool Aluminumâ Grease Filter⤠is an aluminum meshâ capture âŁelement used in Whirlpool overârange and underâcabinet ventilation assemblies to intercept airborne greaseâ before it reachesâ the âblower and âŁductwork. â¤The filter reduces grease deposition on the motor and baffle âsurfaces âbut introduces measurable⤠airflowâ resistance; compatibility depends on theâ filter’s face âŁdimensions, thicknessandâ retention geometry rather than âbrand name alone.⢠Technicians should⢠confirm the â˘part numberâ andâ verify mounting tab spacing⣠and filter orientationâ against the â¤appliance’s model plate or existing filter prior to purchase to⣠ensure a direct fit and⤠correct⤠airflow clearance âin the housing.
Replacement is recommendedâ when the â˘mesh⢠hasâ tears, permanent deformationor cannot be restored by⢠cleaning; repeated compression âor damaged âretention âŁclips â˘will cause â¤vibration and sealingâ failures. Basic installation procedure: de-energizeâ the unit,release the retaining âŁclips or latches,remove the old filter,inspect surrounding seals and mounting hardware,and seat âthe newâ orâ cleanedâ filter so its âretention âfeatures engage evenly. Common troubleshooting indicators include reduced exhaust flow,increased cooktop⣠smoke or odors,audible ârattlingâ fromâ the filter area,and visible grease bypass; if these persist afterâ installing a properly seated W10113040A filter,inspect the âblower âŁwheelâ and âŁduct âfor⢠buildup or obstruction and âverify that mounting clips are secure.
- Pre-replacement checks: confirm part number, measure filter âopening, inspect retention clips.
- Removal/installation steps: power off â ârelease clips â remove filter â cleanâ orâ replace â reseat filter⣠â restore power⣠and⢠testâ fan at all⢠speeds.
