W10113040A Whirlpool Aluminum Grease filter is an aluminum âŁmesh grease filter designed for use in cooking applianceâ ventilation assemblies. It is a âremovable filtration element-typically constructed âŁfrom corrugated or pleated aluminum âmesh â¤within a lightweight frame-intended to capture airborne grease particles âand condensates generated duringâ cooking. As a mechanical filter rather than âa âchemical or catalytic device, it is engineered to trap particulates while allowing a high volume ofâ airflow to pass with minimal⤠added â¤resistance.
Inside⤠the appliance, the grease filter sits in the exhaust or recirculation path and directly interfaces with the blower/fan, ductwork or recirculation⢠grilleand any âŁdownstream odor control media. By intercepting grease and â˘larger aerosols, it â¤reduces deposition on the blower motor, internal cabinet â˘surfacesandâ duct â¤interiors, which⤠helps preserve⢠airflow performance, reduce fire â¤risk from accumulated â¤combustible deposits, â¤and minimize odor and contamination transfer â˘to other household systems. â¤Its material and construction determine durability, cleanabilityand the pressure drop â˘introduced into the ventilation system-parameters that affectâ overall thermal and acoustic⤠behavior of the appliance.
In this⣠articleâ you will find a âtechnical overview ofâ the W10113040A filter’s⣠function and common applications (such as⤠range hoods and overâtheârange microwave exhaust systems), aâ summary of compatibility and identification criteria, typical â¤failureâ and performanceâdegradation symptoms to⤠look for,â troubleshooting steps to isolate filterârelated issues, âand practical⤠considerations for cleaning and replacement. The goal is to provide technicians, engineersand appliance owners with the contextual information needed âto assess whether⤠the filter is functioning⤠correctly and to select or service replacements withâ attention to fit, airflow implicationsand safety.

Function and Role of⣠the Grease Filtration Element in Range Hood and Oven Ventilation Systems
The âW10113040A⢠Whirlpool Aluminumâ Greaseâ Filter is a multi-layer aluminum mesh insert⣠engineered to intercept grease-laden aerosols â¤generated during cooking and prevent their âmigration into⤠the blower, ductworkand exhaust stack. Grease capture occursâ by inertial impaction andâ coalescence âŁon theâ crimped aluminum surfaces: large droplets and â¤agglomerated particles are âtrapped on the mesh⣠while âsmaller aerosols are reduced â˘in downstream concentration.In practice this filter âprotects motor bearings and duct interiors from hydrophobic deposits, reduces the buildup thatâ increases â¤fire loadand âmaintains⤠designedâ airflow patterns so that the hood⤠can âŁmeet its rated âcapture performance when the filter is clean â˘and correctly seated inâ the âŁretainer frame.
Routine behavior and compatibility âconsiderations determine field performance: accumulation of liquid greaseâ and âparticulate increases pressure drop and noise while âlowering â¤capture efficiency, so⢠cleaning frequency should match âcooking load (heavy frying or commercial-likeâ usage requires more frequent servicing). Cleaning consists â˘of degreasing with alkaline detergent and high-temperature rinsing âor a commercial dishwasher cycle; replace the element â¤if the mesh is deformed, puncturedor the retaining tabs are damaged. Technicians⣠should verifyâ that theâ W10113040A installs flush with⤠the âhood frame to avoid bypass leakageand appliance⢠owners should expect noticeable performanceâ degradationâ symptoms such as âincreased smoke in the kitchen, louder â¤fan âŁnoise,⢠orâ oily residue downstream when⤠the filter is saturated.
- Material: anodized/aluminum mesh, washable
- Function: inertial capture and coalescence of grease aerosols
- Maintenance:â periodic degreasing; replace⢠if distorted or corroded
- Compatibility:â designed to fit specific Whirlpool hood/oven retention systems
- Performance impact: clean filter preserves airflow â¤and reduces â¤motor/duct contamination

How⤠the W10113040A Whirlpool Aluminum Grease Filter Works Inside the Appliance: Airflow âŁPath, Oil Capture Mechanism and â˘Mountingâ Interface
The W10113040A Whirlpool âAluminum⤠Greaseâ Filter sits directly in âthe exhaust streamâ of âan overâtheârange hood or recirculating range cabinet where cooking effluent is drawn out of the cook âŁzone. Greaseâladenâ air is accelerated through the⤠hood inlet and âredirected across the filter surface;⢠the âfilter’s corrugated â¤aluminum mesh âand multilayer weaveâ use inertial impactionâ and surface coalescence âto remove oil droplets and aerosolsâ from the flow. âLarger droplets strike the filter foils andâ drain into theâ unit’sâ grease trough,â while smaller particles are captured by successive mesh layers; this âstaged capture preserves the fan’sâ free⣠area longer than âŁa single dense screen and explains why a partially⣠loaded aluminum â˘filter still⣠permits usable airflowâ compared with a clogged disposableâ pad.
The mechanical⤠mounting âŁinterfaceâ forâ this âfilter type is typically a slideâin frame or clip â¤retention system withâ locating â˘tabs that ensureâ correct orientation and a continuous seal against bypass; âŁinstallers shouldâ verify pin spacing and âframe thickness â¤to⣠confirm⤠compatibility before replacement.Routine maintenance affects behavior: accumulatedâ grease reduces effective open area and raises static pressure âseen by the blower, âwhich lowers exhaust flow and can increase noise and motor current.Practical⢠examples: a household that⣠frequently panâfries will need âŁto inspect⣠and clean the âfilter every 4-8 weeks, whereas occasional stovetop use may allow 2-3 months between cleanings. Maintenance ⣠is generally simple-removeâ the filter,â soak in warm detergent, brush â¤and rinse or run through a dishwasher cycle-then reinstall into the original locating slots âso the clip âŁtabs engageâ and the seal is restored.

Commonâ Failure Symptoms and⤠Diagnostic Indicators:â Clogging, Corrosion,â Odor and Reduced Ventilation⤠Performance
The W10113040A Whirlpool âAluminum grease⣠Filter is a removable, â¤aluminum mesh filter designed to⤠capture airborne grease and âŁparticulates upstream of the blower and ductwork in residential range-hood and overâtheârangeâ microwave ventilation assemblies. Its primaryâ function is to provide a coarse trapping medium that â˘prevents grease accumulation on the fan, motorand duct interiors; â˘aluminum offers thermal â¤stabilityâ and corrosionâ resistance in â¤normal kitchen exhaust environments but will still accumulate organic âand particulate âdeposits over⣠time.â Compatibility âis mechanical and performanceâbased: the filterâ must seat correctly âin the housing âto â¤maintain designed airflowâ paths and â¤sealing; an incorrectly⣠sizedâ or deformed mesh will increase leakage and pressure drop even if the media itself is clean.
Common failure modes manifest as clogging, corrosion, âodor generationand measurable â˘drops in ventilation â¤performance. Clogging by⣠condensed grease â˘and carbonized residues â¤increases faceâvelocity pressure drop, which technicians can detect asâ a sustained airflow reduction (such as,â a relative airflow loss⣠of 15-20% or âgreater â compared â˘to aâ cleanâ reference) or as increased motor current and noise under load. Corrosion appears as surface pitting, blackened oxidized areasor eventual perforation of the mesh; perforation both degrades filtration efficiency and âcan permit larger âparticles to reach the blower. Persistent rancid âor burnt odors typically indicateâ trapped organic films that require thorough cleaning or replacement if the â¤meshâ cannot â¤be restored.⤠Simple diagnostics include a⤠visual inspection for âgrease layers and pitting, a before/after anemometer⣠or vaneâmeter airflow check â¤with the filter installed versus removed, â˘and a motor current measurement toâ detect increased load; if cleaning does ânot restoreâ geometry and airflow, replace the filter.
- Visible heavy grease loading orâ carbonized residue on mesh
- Persistent cooking odors â¤after cleaning âcycle
- Increased fan noise or â˘higher motor current⣠under normal settings
- Surface â¤pitting, dark oxidation spotsor mesh perforation
- Measured airflowâ reduction >15-20% relative to a clean baseline
| Item | Description |
|---|---|
| Clogging | Grease and particulates form layers âthat â¤increase âpressure dropâ and reduce CFM. |
| Corrosion | oxidation/pitting of aluminumâ that may lead to perforation and loss of structural integrity. |
| Odor | Trapped organic â¤residues produce persistent âsmells even after superficial⣠cleaning. |
| Reduced ventilation⢠performance | Lower airflow, higher⢠motor current,â and increased â˘noiseâ indicate degraded filter function. |
compatibility, Replacement Considerations and Installationâ Procedures for the W10113040A Whirlpool Aluminum Grease Filter
the W10113040A Whirlpool Aluminum Greaseâ Filter is a stamped, reusable âaluminum âcaptureâ element used in many Whirlpool range hoods and over-the-rangeâ microwaveâ exhaust assemblies. Its folded-baffle geometry forces airflow to âchange âŁdirection, causing oil⢠droplets and large particulate to coalesce⤠on the aluminum surfaces andâ drain into a collection âtrough; this design provides high particulate capture with relatively low pressure drop âcompared with fine mesh filters. As it is indeed a âmechanical capture device rather than an adsorbent, âit does not remove⣠odors; odor âcontrol requires a separate charcoal or catalytic â˘cartridge.Confirm compatibility by matching the appliance⤠model number, âfilter footprintand the clip/tab orientation – many filters âare physicallyâ interchangeable only when the mounting bracket and access panel align âwith the part’s edges and retention âfeatures.
Replacement and installation should focus on fit, integrity of the frameand â¤restoring unobstructed airflow.Inspectâ the filterâ for corrosion, crushed or loose â˘edgesand permanently adhered oil; âcleanable â¤aluminum filters should beâ removed, degreased, rinsedand dried before reuse,⢠but replace the unit if the drain channels areâ blocked or the frame no longer seats squarely. Typical â˘installationâ steps⤠used by â¤service âtechnicians are:
- Disconnect power to⣠the range hood or microwave assembly.
- Release the retention âclips or⤠slide the access⣠panel to free the âoldâ filter â¤and remove it âfrom the housing.
- Verify the new filter’s orientation and⢠seating surfaces, âthen â˘insert it untilâ it⤠engages the retaining slots âor clips.
- Secure the retention hardware,restore the access panel,and reapply power; run the fan to check for rattles and normal âairflow.

Q&A
What is the W10113040A aluminum âgrease filter used for?
The W10113040A is an OEM aluminum mesh grease filter designed to capture cooking grease and large particles in the exhaust⤠system of compatible Whirlpool â(andâ some Kenmore/Maytag) â˘overâtheârange microwaves and range â˘hoods. It is indeed a washable, reusable filter that protects the blower and ductwork from grease buildup.
How do I know if⢠W10113040A⤠is compatibleâ with my appliance?
Check yourâ appliance model number âagainst Whirlpoolâ parts lookup (manufacturer website or authorized parts dealers).â You can â˘also look for the⢠part numberâ on⢠the existing filter or in your owner’s⣠manual.⣠If the part number isn’t listed, âsupply your appliance model number â¤to â˘a âŁparts supplier to â˘confirm compatibility.
how do â¤I â˘removeâ and install the W10113040A âfilter?
Turn â˘off âŁthe appliance and make sure it is indeed cool. âMost â¤filters â˘are held by a latch or spring clips-release the clip, slide or tilt⢠the â˘filter out of its frameand remove. â˘To install, position the filter âinto the frame âand engage the âŁclip or latch until it is âsecure and sits flush. Do not force the filter; it should seat smoothly if aligned correctly.
Canâ I clean theâ W10113040A filter in the dishwasher?
Yes, the⢠aluminum meshâ filter is dishwasherâsafe. Use a normal wash cycle (top rack) and avoid highâheat drying cycles that can warp clips. Repeated dishwasher use can dull the finish; hand washing with warm water and a degreasing detergent or a soak â˘in a solution âof warm water and vinegar/baking âŁsoda plus a âsoft brush will âŁbe âgentler and extendâ filterâ life. Always dry the filter â˘entirely before reinstalling.
How often should I clean or replace the W10113040A filter?
