239087 Whirlpool Dryer Rear Drum Seal⢠Green Stiches is a rear drum seal assembly⢠used on âselect Whirlpool dryer⢠models; âŁit is a felt-type sealing/bearing âinterface that mounts at the rear bulkhead where the dryer drum meets the⣠cabinet. The component typically â¤consists ofâ a compressed felt or fabric ring withâ a stitched reinforcement (identified here âby the green â˘stitches) designed toâ control drum-to-bulkhead clearance, reduce fabric snags, âadn limit air leakage around the drum shaft.
Inside the appliance the rear⢠drum seal interfaces directly with the rotating drum, the bulkhead â¤or âŁhousingand indirectly with theâ drum support system (rollers or bearings), theâ drive assemblyand âthe dryer’s airflow/heating circuit. Proper function of the seal helps maintain intended airflow paths and pressure differentials,â preserves drum⤠concentricityand reduces⣠metal-to-metal contact and âabrasive wear onâ clothing. When degraded, the seal â˘can⣠contribute to increased air leakage, reduced heating efficiency, abnormal noise, accelerated âwear of âŁadjacent componentsand potential lint intrusion into the ârearâ enclosure.
in⣠this article â˘readers will find a technical overview of the âpart’s âŁfunction, guidance on⣠model compatibility and cross-references, typical⤠failure symptoms to recognize (wear, fraying, increased dryingâ times, noise, visible⤠gaps), step-by-step troubleshooting checks to isolate â¤the seal as theâ root causeandâ practical replacement considerations. Those replacement considerations⤠include⣠inspection and testing of⢠associatedâ supports (rollers, bearings, shaft), correct⣠orientation and seating of theâ felt seal, tools and access required for removal/installationand verification steps to ensure restored drum alignment and airflow⢠performance âafter service.

Function⤠and Role of the Rear Drum Seal in Whirlpool Dryers
The â¤rear â˘drum seal forms the radial and axial interface between the rotating drum and the dryer bulkhead,controlling airflow,keeping lint out of the rear bearing area,and providing âa wear⢠surface that damps vibration.The â 239087â Whirlpool Dryer âRear Drum Seal Green Stiches is a replacement rear seal that uses a colored⢠stitch pattern for identification and⤠edge retention; functionally it acts as a⢠low-friction lip that remains in contact with the drum flange to âpreserve directed airflow⣠throughâ the lint â˘trap and heating assembly while permitting free rotation. In operation the seal compresses into a mounting groove âŁand must retain its profile under repeated âthermal cycling and â˘tumble abrasion to avoid leaks that cause reduced drying efficiency or lint â˘buildup behind theâ drum.
Compatibility depends on mating dimensions âand âmounting method rather than brand alone: the rear âdrum seal must match⢠the drum outer diameter, the bulkhead groove widthand the axial clearance⢠so the lip maintains continuous contact without excessive drag. technicians shoudl â¤inspect for hardening, tears, missing stitches,⤠or a âflattened lip profile; â¤common functional failures present as âincreasedâ noise (squeal or rubbing), â¤visible lint accumulation at the rear outletand measurable heat âŁloss into âŁthe cabinet. When âreplacing the seal, verify inner diameter, groove engagementand stitch orientation â˘so replacement parts âseat correctly and⣠maintain⢠the original shaft-to-seal clearance for reliable operation.
- Primary functions: airflow sealing, lint exclusion, vibration dampingand wear protection.
- Failure symptoms: rubbing/squeal, rear lint accumulation, longer dry timesor observed âlip deformation.
- installation checks: match inner diameter, groove widthand ensure even compression around âdrum⤠circumference.
- Material behavior: designed⣠to flex⣠with thermal cycles âand resist abrasion from tumblingâ load andâ lint particles.

How the 239087 Whirlpool Dryer Rear Drum Seal Green Stiches Works Inside the Appliance
The â¤239087 Whirlpool Dryer rear drum Seal Green stiches is a molded felt⣠seal that⤠establishes a controlled âradial contact between the drum rear⤠flange and the bulkhead. Its primary function âis to maintain the dryer’s designed airflow path by â¤limiting air and lint âŁleakage past⢠the drum,while providing a âlow-friction sliding surface that reduces noise â¤and âwear on the drum edge.The green stitching is a factory-applied identifierâ and reinforcement along the mounting flange; technicians use âthe âstitch line to confirm correct orientation and to spot early thread failure that can lead to âuneven sealing.
In operation the seal is subject to mechanical abrasion,⣠heat cycling and compression set; typical â¤failure⤠modes are fraying at the stitch line, loss of compliance where the felt no longer conforms to the drumand hardening of theâ contact âlip âŁthat increases friction andâ noise. Replacement is advised when visual inspection shows tornâ orâ separated stitching,â when lint accumulates behind⣠the â¤drumor when drying âperformance declines due to air leakage. Verify compatibility by matching the appliance âmodel and part ânumber⤠to â˘239087 and inspect adjacent components (drum rollers,rear bulkhead) âduring service âto ensure the new seal seats evenly and isâ not âŁexposed to scuffing or misalignment after installation.
- Common âŁsymptoms: squeal or rubbing noise during⤠rotation, increased cycle⣠times, visible lint behind the drumand frayed green âstitching.
- Service tip: orient the stitch-mark toward â¤the access side⣠per factory marks and â¤confirm even compression around the circumference âŁbefore reassembly.

Common failure Symptoms and Diagnostic Indicators âof Rear Drum Seal Wear
The 239087 Whirlpool Dryer Rear Drum âSeal Green stiches is a fabric lip seal⢠mounted at theâ rear drum âflange that prevents lint, moisture and air from âinfiltrating the bearing/motor cavity while maintaining drum concentricity. Its construction-fabric or â¤felt body âŁwith a⣠stitched reinforced⤠edge-provides a low-friction contact surface against the drum rear face; the green stitching is a manufacturing identifier but fit and function are determined⣠by the mounting âdiameter, lipâ thicknessand âstitch âorientation. proper compatibility requires⢠matching the part number or confirming that the seal’s outer diameter and mounting tab spacing align with the dryer⣠bulkhead; an otherwise similar-looking⣠seal can allow misalignment or excessive drag if dimensionsâ differ.
Wear of âthe rear drum sealâ produces characteristic mechanical âŁand airflow â¤symptoms that help distinguish it from bearing or belt issues. Technicians shouldâ inspect the⤠seal lipâ for compression, tearsor stitched-edge failure and verify airflow âŁand drum runout⤠by⣠rotating the drum by hand; â˘carcass friction and⣠lint migration toward the rear are primary diagnostic indicators. A â˘visual comparison to a âknown-good 239087 part, checking âfor grease or metal debris (which would point to bearing failure rather)andâ noting whether noise tracks circumferentially âŁwith drum rotation âŁare practical steps âto confirm seal wear and determine replacement necessity.
- Visible lint accumulation⣠at the rear bulkhead – indicates compromised⤠sealing and bypass airflow.
- Rubbing or fabric-on-metal noise that follows drum rotation – suggests worn or displaced âŁlip⣠contact.
- Increased vibration or⢠drum wobble without metallic⢠grinding – consistent with lost concentricity from seal collapse.
- Flattened, tornor missing stitching on â˘the seal edge – direct evidence the seal has reached end-of-life.
- Elevated exhaust temperature localized to rear cavity – sign of restricted or redirected airflowâ due to â¤seal failure.
Replacement Considerations and Step-by-Step Installation for Part 239087
The 239087 Whirlpool Dryer Rear âDrum Seal green Stiches is a stitched felt seal that mountsâ to the dryer rear bulkhead â¤and bears against â˘the drumâ rear lip to control axial clearance and limit air bypass into the motorâ and blower cavity. Its stitched (green) reinforcement maintains⢠edge integrity againstâ centrifugal forces and repeated thermal cycles; the felt âcompresses to form a low-friction contact surface while the stitching prevents delamination. Functionally the part reduces lint migration, stabilizes⣠drum end playand protects bearings and electrical components from âlint and moisture;⤠verify âfit by matching the rear bulkhead mounting pattern, drum flange diameterand shaft clearanceâ on the specific âWhirlpool model before â¤ordering a replacement.
Replacementâ choices should be driven by observable wear-flattened or torn felt, frayed stitching,⢠increased⤠lint accumulationâ inside the cabinetor new rubbing noises-ratherâ than arbitrary time âintervals. âTypical installation sequence for technicians: disconnect âŁpower,â remove access panels, release belt tension and support the⢠drum, remove the â˘old⣠seal and thoroughly clean the seating âŁsurface, press the new seal evenlyâ into the bulkhead âensuring correct orientationâ ofâ the stitched edge, reassemble in reverse order and run⣠a short test cycle to⢠confirm âŁeven drum rotation and the absence ofâ rubbingâ or excessive air leakage. âFor tight fits or deformed bulkhead bores, lightly cleaning and deburring the seating area improves contact; do not use adhesives that âŁcan outgas under heat or alter the intended compression of the felt. â
- Symptoms prompting âreplacement: visible felt⣠damage, persistentâ lint downstream, unusual end-play or rubbing ânoises.
- Compatibility checks: match â˘part number, bulkhead bolt pattern,â drum flange diameterand shaft clearance before purchase.
- Readiness: cut power, document belt routingand have⣠basic tools (socket set, screwdrivers,â work light) and cleaning supplies ready.
- Key installation steps: remove âpanels ââ support drum â remove old seal â clean seat â installâ new seal⢠evenly â reassemble â test run.
- post-install verification: confirm even âdrum rotation, no scraping sounds,⢠and reduced lint âŁin the blower/motor area after⢠several cycles.

Q&A
What is the 239087 Whirlpool Dryer Rearâ Drum Seal with green⤠stitches and what does it do?
The 239087⣠rear drum seal⣠is an OEM replacement felt/rubber seal that sits between⢠the⢠dryer cabinet and the back of the rotating drum. Its job⤠is to keepâ hot air inside the drum, reduce noise and friction between drum and â˘cabinet,â and help prevent clothing or lint from â¤getting trapped between the drum and housing. âŁThe green⤠stitches are a manufacturing/identification detail of the felt assembly and do not change the seal’s function.
how can I tell âif the rear drum seal needs replacing?
Common⣠signs include a rubbing or squealing noise as the⢠drum turns, visible wear or fraying of the felt,⤠hot air leaking into the cabinet,⢠increased lint buildup behindâ the drum, â˘and â˘clothes showing signs of abrasion where they contact the drum edge. Excessive drum play or a worn rear⣠bearing can produce similar symptoms, so inspect â¤the seal and surrounding parts before replacing.
Which dryer models does part⣠239087 fit?
239087 is an OEM âWhirlpool-style rear drum seal used on a⤠range of Whirlpool, Kenmore and related-brand dryers. Fitâ varies by model and year, so alwaysâ confirm compatibility âby checking your dryer model number against the partâ listing on the manufacturer’s partsâ site or your service manual before ordering.
How difficult is it to install the 239087 rear drum seal and what tools are âneeded?
Installation difficulty is moderate. You âwill normally â¤need⤠basic â˘hand tools (screwdrivers, nut drivers or â¤socket set, pliers)⣠and possibly a putty knife or trim tool to pry panels. Typical steps include â¤unplugging the dryer (and shutting off gas for gas dryers), removing the dryer cabinet or⣠rear panel, dropping or removing the âdrum, removing⣠the old seal, â¤cleaning the mounting surface,â and fitting⢠the new seal. Allow 30-90 minutes depending on experience. If you’re not comfortable disassembling the âŁdryer, consider â˘a qualified technician.
Do I need adhesive orâ special â˘fasteners to install this âŁseal?
That depends⣠on your dryer’sâ design. Some seals slip âinto a channel or are held byâ the drum flange and ârequire no adhesive; âothers use a âretaining âclip or a few stitch points. If adhesive is required, use⣠a high-temperature, appliance-grade adhesive specifiedâ for dryer seals. Follow the OEM service instructionsâ for your model to avoid improper installationâ that could cause premature wear or â¤airflow leakage.
Can I replace only⢠the rear sealor should I replace other parts too?
You can⢠replace just the rear seal if it’s the only worn component. However, it’s a goodâ idea to inspectâ the front seal/felt, â˘drum rollers, idler, glides,⤠and rear bearing â¤while the dryer is âdisassembled.If those parts show wear, replacing them at the same time can âsave labor and prevent future problems.
Are the green stitches important for performance or are there color/brand variations I⤠should be awareâ of?
The greenâ stitches are mainlyâ a manufacturing/identification feature for that part. â¤Functionally, theâ color does not affect performance. When buying âa replacement, prioritize correct part number and fit rather thanâ stitch color. OEM or high-quality aftermarket seals⢠that match the original dimensions and attachment âstyle are recommended.
Any safety or maintenance tips after âŁinstalling the â˘new rear âdrum seal?
After â¤installation, reassemble the âdryer⤠correctly and test for smooth, quiet drum rotation before running âa full load. Keep lint traps and vents clean â˘to reduce heat and wear on seals, avoid overloading the dryerand periodically inspect seals and drum support components for wear. Always disconnect power (and gas) before servicing the dryer âŁto avoid shock, burns,⤠or injury.
