W10113040A Whirlpool Aluminum Grease Filter is an OEM-designated aluminum mesh grease â¤filter used in household cooking appliance ventilation systems.â It is a passive filtration âelement âtypically constructed from âfolded âor âlayered aluminum mesh that â¤captures liquid and particulate⢠grease âfrom the exhaust airstream. As⢠a mechanical barrier, it is indeed intended⣠to be serviceable (cleanable) and toâ fit into a dedicated filter frame or slot within the applianceand its form factor and⣠mounting tabs are specific to compatible Whirlpool⤠range hoods and over-the-range microwave/vent â˘assemblies.
Inside the appliance the âfilter is positioned upstream⢠of the â˘blower assembly⣠and, where present, upstream of ductwork or charcoal odor âfilters. It interactsâ directly âŁwith the âŁexhaust â¤fan, intake openings, lamp housings and the appliance’s internal âŁair passages: by⢠intercepting grease it reduces âdepositionâ on the blower⤠motor, fan blades, ducts âand electricalâ components, â˘and âit influences system airflow via added âŁpressure drop âŁas contaminationâ accumulates.â Proper function therefore affects ventilation⤠efficiency, â¤motor loading â˘and⣠long-termâ reliability âof downstream componentsand a compromised or clogged filter can increase fire risk and degrade performance.
This article will describe the filter’s functionâ and⣠construction, list compatibility and dimensional considerations forâ selecting the correct replacementand identifyâ common failure modes and observable symptoms such as reduced airflow, increased odors, smoke⤠during heavy cooking or visible damage to the mesh.⤠It will also cover practical troubleshooting steps andâ decision â¤criteria for cleaning versus replacement, mounting and sealing âconsiderationsand â¤service safety notes so technicians, engineers and owners can assess condition, verify âŁfitment and determine⤠appropriate repair actions without relying on marketing⢠claims.

Function and Role of âthe Grease Filter â˘in Whirlpool Range Ventilation and Safety
The W10113040A Whirlpoolâ Aluminum âGrease Filter â˘isâ a perforated/mesh â¤aluminum element installed in range ventilation assemblies to intercept oil droplets and solid combustionâ byâproducts before they reach the blower, ductwork, â¤or external exhaust. its fine mesh âŁcaptures grease⢠by impaction and coalescence, allowingâ larger âdroplets to drain⤠back into the canopy while permitting the ârequired airflow for the â¤exhaust fan; when clean â˘it introduces âonly a small, predictable pressure drop, but grease loading increases â˘pressure drop⢠and fan work. This component isâ a mechanical âŁgrease âtrap only – it does not remove âŁodors âŁlike activated carbon – and is designed⤠to be compatible with âŁspecificâ Whirlpool range hoods and âreplacement â¤slots that accept an⣠aluminum mesh â¤cartridge of the appropriate dimensions and retaining clips.
- Primary roles: capture grease, protect blower/motor, reduce downstream âduct fouling and ignition risk.
- Behavior:⢠mesh⤠increases pressure drop as it âloads; visible oilâ sheen and decreased⣠airflow are early indicators âof clogging.
- Maintenance cues: inspectâ monthly for heavy cooking, clean or replace if bent, torn, â˘or â˘corroded.
- Compatibility: intended asâ an OEM-style replacement forâ Whirlpool vents that accept â¤an aluminum mesh element; not a universal odor filter.

|---|---|
| Material | Aluminum mesh/perforated cartridge â- lightweight and⤠corrosionâresistant but âcan discolor with ârepeated dishwasher exposure |
| Function | Mechanical grease capture âto protect fan and ducts |
| Maintenance | Clean with hot âdetergent âor degreaser; frequency based on cooking loadâ (typical: monthlyâ to quarterly) |
Forâ practical âservice and troubleshooting, remove the⣠filter and inspect both faces and⢠the mounting flange forâ accumulated film, pinholes,⣠orâ distortion;â persistent high static pressure or â¤elevated âmotor current after cleaning âindicatesâ either incomplete cleaning or mechanical damage that warrants replacement.Cleaning methods âŁthat work in âthe field include degreasing soak âŁandâ hand brushing or runâthrough âŁdishwasher cycles âwhereâ allowed by the appliance manual – verify fit and secure retention⣠after reinstallation to maintain proper airflow â¤paths âand minimize bypass. Replace the âfilter when âŁmesh openings are⢠enlarged, seams are âseparatedor âretention hardware is damaged, as a â¤compromised filter reduces protection â¤for downstream âcomponents âand can âŁaccelerate combustion residue buildup in the ducting.
How the W10113040A Whirlpool âAluminum Grease Filter Works⢠Inside the Appliance
The â W10113040A Whirlpool aluminum Grease⢠Filter is⤠a multi-layer aluminum mesh element installed in range hoods and⣠overâtheârange âmicrowave exhaust systems to âremove airborne oil and particulate from the⢠exhaust stream.Its primary capture mechanisms are inertial impaction and âcoalescence: oil droplets and⣠solid particles follow airflow paths that force them âto strike and adhere âto the meshâ surfaces, where they accumulate into larger droplets that drain back into the âŁgrease collectionâ area. The filter is designed â¤to balance capture efficiency with acceptable pressureâ drop âso the blower canâ maintain rated airflow without âŁexcessive noise or âenergy loss.
- Function: traps grease,â prevents blower and duct⢠fouling
- Behavior: âallows airflow while⢠collecting droplets âthrough multi-layerâ mesh
- Maintenance: washable; frequency depends on cooking load (heavy frying⢠accelerates âbuildup)
- Compatibility: fits select âwhirlpool venting assemblies-verify part number against model âmanual
In service, the filter âshould seat securely in âits âframeâ to avoid bypass paths that⢠reduce capture âŁperformance; a leaking or warped filter will substantially increase duct contamination and maintenance â¤on the blower âmotor. Technicians⤠should inspect for deformation, broken mesh layersand excessive residualâ deposits-filters with severe pitting or seam failureâ should be replaced rather⣠thanâ cleaned. âFor âŁpractical âmaintenance, â˘removeâ and⤠degrease the filter with âwarm detergent or a dishwasher âcycle, âlet it dry fully,â thenâ reinstall⤠with⤠the airflow direction and locking⣠features aligned to the appliance’s retention clips.

Common Failure â¤Symptoms andâ Diagnostic Indicators⣠of Grease Filter âDegradation
The W10113040A Whirlpool â¤Aluminum Grease Filter is a reusable baffle-style element designed to capture airborne grease and largeâ particulates before they âreach the blowerâ and ductwork. In service it relies on⣠abrupt changes in airflow and impingement⣠on âcorrugated aluminum surfaces to âseparate oil droplets; as the filter saturates or sustains physical damage (bends, perforationsor corrosion) its capture efficiency falls and pressure drop across the element increases, âwhich directly reduces exhaust CFM⣠and can accelerate blower wear. Verify part compatibility and correct orientation in the range hood assembly, since an improperly seated W10113040A will create bypass paths â˘andâ mimic the symptomsâ ofâ degradation evenâ if â˘the â¤media is clean.
Technicians canâ diagnose⢠degradation⢠through a combination of visualâ inspection âŁand quantitative checks: look for hardened or pooled oil on the filter surfaces, â¤visibleâ perforations or warpingand grease âthat âtransfers to⣠ductwork or applianceâ surfaces. âMeasure system performance against a known clean baseline-an airflow lossâ of roughly 15-20% âor a sustained rise in static pressure or blower current beyond normal operating variation indicates cleaning orâ replacement âis required. Practical troubleshooting steps â˘include a manual clean cycle⤠to confirm recoverable⢠performance, measuring blower â˘current and inlet static pressure beforeâ andâ after⤠filter servicingand replacing the â¤aluminum element if cleaning does not restore baseline âmetrics.
- Reduced âairflow/CFM (â15-20%⣠drop relative to⣠baseline)
- Persistent smoke, cooking odor, âor greaseâ residues downstream
- Visible corrosion, holes,â deformationor oil pooling on the filter
- Increasedâ blower noise⤠or higher motorâ currentâ under the â¤same operating conditions
| Item | Description |
|---|---|
| Airflow reduction | Loss âĽ15% vs. clean baseline suggests âblockage or saturation-clean and retest; replace if no improvement. |
| Physical damage | Perforations, bent framesor meaningful â¤corrosion require replacementâ to prevent grease bypass and fireâ risk. |
Compatibility, Replacement Considerationsand Installation⤠Procedures for Range Grease âŁFilters
The W10113040A Whirlpool Aluminum Grease Filter is a⤠passive, non-electrical component⣠composed of folded âaluminum mesh designedâ to intercept grease-laden âaerosols⣠in range hoods and âoverâtheârange microwave exhaust systems. Functionally it reduces grease â˘deposition in ducts and on blower â˘wheels âby coalescing droplets and trapping⤠particulate;â this alters pressure drop across⤠the inlet, so verify that replacement filters⤠match the original filter’s thickness, âmesh density,⣠and mounting footprint to maintain designed airflow âŁand backâpressure. Compatibility is⤠persistent by three measurable attributes: â¤part number,cutâout/overall dimensions,and latch âor clipâ orientation – matching âthes âŁprevents â¤fit,sealing,and airflow issues that can degrade performance or increase â¤noise.
replacement andâ installation â˘are straightforward but â˘require attention to interface details and serviceability. Inspect âthe âŁfilter frame for warping or broken tabsâ and the hood sealing surface for damage before reinstalling; if the â¤aluminum mesh is torn, âheavily âfouled beyond cleaningor the frame â˘is deformed, replace rather than attempt repair. Typical installation steps include cleaning or replacing the filter, confirming correct orientation of the greaseâdrip side and retention clipsand running the appliance briefly to validate airflow âand check for vibration or rattle. Below are practical checks and actions technicians âuse during â˘service.
- remove retention clips or âdisengage⢠the frontâ latch and slide theâ filter out; if tight,⤠support the filter while releasingâ fasteners to â¤avoidâ dropping it into the blower âcavity.
- Clean reusable⢠aluminum filters with degreasing solution andâ hot water, dry whollyand inspect mesh seams; replace if holes, â¤separation,â or⤠severe corrosion⣠are present.
- On replacement, confirm part number, overall length/width/thicknessandâ mounting tab spacing beforeâ installation; secure clips and verify the filterâ seats flat⢠against âthe⣠hood frame to âavoid bypass leakage.
- After installation, runâ the fan at each⢠speed toâ checkâ for abnormal sound or reduced airflow; excessive restriction may âindicate incorrect mesh density âor a misfit filter.
