134728400 Frigidaire Bellows Kit is a replacement bellows assembly designed for use in Frigidaire appliance mechanisms. The bellows itself is a flexible, accordion-like elastomeric component supplied as a kit (typically including the molded bellows and any necessary clamps or mounting hardware) that provides a sealed, movable interface between two assemblies. In service it functions as a mechanical seal and motion-transmission element rather than an electric or electronic part, and its construction and dimensions determine its fit and sealing performance within the appliance.
Inside an appliance the bellows acts to isolate fluids and contaminants while allowing controlled axial or radial movement of a linkage, plunger, or valve stem. Technically, it preserves a pressure or moisture barrier while transferring mechanical travel from a user input or actuator to an internal mechanism; common interactions include water or ice dispensing systems, dispenser actuator linkages, and valve or sensor interfaces where a sealed moving joint is required.For a technician or engineer, relevant parameters include material compatibility with water and cleaning agents, allowable travel and spring-back characteristics, mounting geometry, and the sealing interface against housing and mating components.
In the following article readers will find a focused technical overview covering the bellows’ intended function, how to verify compatibility with specific frigidaire models and cross-reference part numbers, common failure symptoms (cracks, deformation, leaks, loss of actuator return), and practical troubleshooting steps such as visual inspection, leak checks, and cycle testing.The guide will also address replacement considerations: verifying OEM part numbers and orientation, removing and installing the bellows without damaging adjacent components, appropriate fasteners or clamps, and post‑service functional checks; basic safety steps such as disconnecting power and shutting off the water supply before service are also emphasized.

Function and Role of the Bellows in the Door Seal Assembly
The 134728400 Frigidaire Bellows kit is a molded elastomer boot designed to create a flexible, watertight interface between a front-door assembly and the appliance tub on models that use a bellows-style door seal. The bellows absorbs the mechanical movement of the door, maintains continuous contact under clamp tension, and isolates the wash chamber from the cabinet to prevent leaks and vapour escape. compatibility is determined by flange geometry, clamp type, and overall bellows depth; technicians shoudl confirm appliance model numbers and reuse or replace the retaining spring, inner retainers, and any locating tabs to ensure a proper fit and sealing orientation during replacement.
The bellows functions by flexing under repeated door cycles while resisting chemical exposure from detergents and varying temperature cycles; loss of elasticity,punctures,or flange warping are common failure modes that produce observable symptoms such as water tracking,pooling on the floor,persistent odors,and mold accumulation at the seal. Practical inspection points and functional features include:
- Material resilience: corrugated elastomer must remain pliable to seal under compression.
- Sealing interface: continuous flange contact with the door and tub surfaces without gaps or folds.
- Mechanical attachment: intact clamp/spring and undamaged retainer lips for consistent clamp pressure.
- Failure indicators: visible tears, hardening, or dimensional distortion preventing proper seating.

How the 134728400 Frigidaire Bellows Kit Works Inside the appliance
The 134728400 Frigidaire Bellows Kit serves as the flexible, watertight interface between the appliance door and the inner tub, forming an accordion-style boot that accommodates door movement and pressure changes during cycles. Installed in the door opening, the bellows mates to a groove on the outer tub and to the door flange, and is held in place by a retention band or spring; its profile channels splashed or recirculated water back into the wash path rather than allowing it to pool at the door. Functionally, the kitS geometry and material stiffness determine how the seal responds to drum rotation and spray patterns, so correct orientation and full seating of the lip are necessary to maintain a reliable seal under varying temperatures and detergent chemistries.
- Flexible accordion design allows axial movement and compresses/expands with pressure changes.
- Sealing lip engages a tub flange and door flange; retention is typically by a clamp or spring band.
- Common failure modes: tears at the fold, compressed or flattened pleats, and degradation from heat or chemical attack.
| Item | Description |
|---|---|
| Primary function | Maintain a watertight path between door and tub while allowing motion |
| Mounting | Groove-to-flange fit with clamp/spring retention |
| Typical symptom of failure | visible drip or pooled water at the door edge during or after a cycle |
In practical service, technicians verify compatibility by matching the kit to the appliance model and assessing the mating surfaces for corrosion or distortion before installing a replacement; mismatched diameter or worn tub flanges will produce leaks even with a new bellows. During diagnostics, running a short rinse or spin while observing the door perimeter often reveals leaks caused by misalignment, degraded material, or loose clamps; resolving the issue typically requires cleaning mating surfaces, confirming the bellows lip is fully seated around the entire circumference, and applying the correct clamp tension rather than relying on adhesive or temporary fixes.
common Failure Symptoms and Diagnostic Indicators of a Faulty Bellows Kit
The bellows in a laundry or dishwasher assembly is a molded flexible boot that forms the watertight, pressure-stable junction between the tub and the appliance access opening; a worn bellows will compromise that seal and produce the symptoms described below. The 134728400 Frigidaire Bellows Kit replaces the flexible seal and associated clamps, and must match the flange geometry, rib pattern, and clamp size of the original to restore proper sealing and mechanical alignment. Compatibility questions are not only about part number matching: differences in flange diameter, flange thickness or rib spacing can allow leaks or permit the bellows to rub against moving parts, accelerating failure in service.
- Visible tears, punctures, or delamination along folds or flange edges
- Persistent water leakage during fill, wash, or drain cycles
- Unusual rubbing noises or abrasion marks indicating misalignment
- loss of elasticity - bellows stays deformed after compression
- Clamps missing, loose, or corroded at the mounting flanges
Diagnostic checks begin with a hands-on inspection: remove the access panel, visually examine the bellows around the entire circumference for hairline cracks, soft spots, or separations, and manually flex the folds to confirm springback. Perform a dynamic test by running a short wash or rinse cycle while watching for leaks at the flange joints and along the folds; a colored dye added to the wash water can help localize a slow leak.If there is water ingress into adjacent housings or insulation, inspect electrical components and motors for contamination. Restoring function reliably typically requires replacing the bellows and all mounting clamps with parts that match the original geometry, then verifying the repair by repeating the pressurized cycle test and confirming absence of rubbing or load changes on the drive system.
| Item | Description |
|---|---|
| Visible tear | Crack, hole, or delamination in the bellows material causing direct leakage. |
| loose/clipped clamp | Missing or corroded clamp allows flange slip and loss of seal under pressure. |
| Loss of elasticity | Brittle or deformed bellows that does not recover, creating gaps during cycles. |
Compatibility and Supported Frigidaire Appliance Models for the 134728400 Bellows Kit
The 134728400 Frigidaire Bellows Kit is a molded flexible boot that provides a sealed, articulating interface between a refrigerator’s fixed cabinet and a moving component (door, drawer, or hinge bonnet). Its primary function is to maintain the intended air barrier while permitting repeated opening and closing; if the bellows tears, hardens, or detaches the seal path, conditioned air will migrate, resulting in frost accumulation, increased compressor run time, and localized condensation. The kit normally includes the bellows body and any small mounting tabs or retainers needed to secure it to the cabinet and hinge, and it is specified to resist flex fatigue, moderate refrigerant-side temperatures, and the chemical exposure typical inside appliance enclosures.
Compatibility depends on the mechanical interface rather than the refrigerator’s marketing name: the same 134728400 bellows will fit multiple Frigidaire models that share the same hinge geometry, flange spacing, and attachment method. To verify support for a specific appliance, compare the OEM part number on the service sheet, inspect the existing bellows for matching mounting tab locations, and measure the distance between mounting flanges and the bellows free length. Practical checks and common indicators that the bellows is the correct replacement include torn or compressed material at hinge pivot points, visible air leakage or frost at the interface, and a match between the replacement’s flange profile and the cabinet cutout; technicians often confirm compatibility by matching the part diagram in the model’s service manual before installation.
- Compatibility checks: OEM part number, flange spacing, mounting tab pattern, and service diagram match
- Failure symptoms that indicate replacement: tears at flex points, persistent frost/ice, and water pooling under cabinets
- Installation note: ensure retainers or clips are correctly seated to prevent premature detachment
| Item | Description |
|---|---|
| Typical application | Sealing moving door/drawer interfaces on Frigidaire upright refrigerators and freezers with compatible hinge geometry |
| material | Flexible EPDM or thermoplastic elastomer selected for flex-life and temperature resistance |
| Key dimension | Mounting flange spacing and free length determine fit; measure existing part for confirmation |
Q&A
What is the 134728400 Frigidaire Bellows Kit?
The 134728400 frigidaire Bellows Kit is an OEM replacement bellows (also called a door boot or gaiter) – a flexible rubber seal that attaches between the appliance door and the tub/drum on certain Frigidaire front‑load washers (and some other models).Its purpose is to keep water inside the wash tub and to provide a flexible, sealed connection while the door is opened and closed.
How can I tell if the bellows needs to be replaced?
Common signs are visible tears,cracks,or holes in the rubber; persistent leaks from the front of the machine during fill or drain cycles; heavy mold or mildew that won’t clean out; or deterioration where the bellows no longer seats tightly against the door or tub flange. If you find a split or the bellows is pulling away from its clamps, it should be replaced.
Wich Frigidaire models is part number 134728400 compatible with?
Compatibility varies by model and production date. Always check your appliance model number (usually on a tag behind the door or on the cabinet) and compare it to Frigidaire’s parts list or an authorized parts supplier. Don’t rely on visual similarity alone – verify fitment using the model number or Frigidaire parts lookup to ensure the correct kit for your unit.
Can I install the bellows kit myself, or should I call a technician?
Many mechanically pleasant homeowners can replace the bellows themselves; the job is medium difficulty. You must be comfortable moving the front panel/door, loosening and tightening clamps, and re-seating the gasket. If you’re unsure, not experienced with appliance repair, or if the washer has other issues (bearing or tub damage), calling a qualified technician is recommended.
What tools and supplies do I need to replace the bellows?
typical tools: screwdriver set (Phillips and flat), pliers, socket set, putty knife or trim tool to pry retaining rings, and a towel or small bucket to catch water. Supplies: the replacement bellows kit (134728400), new clamp rings if not included, mild dish soap or a rubber‑safe silicone lubricant to help seat the new bellows, and gloves. Always unplug the machine and turn off the water supply before starting.
What are the basic steps to replace the bellows?
High‑level steps: 1) Unplug the washer and turn off the water. 2) Open the door and remove any screws or the front trim required to access the bellows clamp. 3) Loosen and remove the outer clamp and peel the old bellows away from the door. 4) Detach the inner clamp from the tub and remove the bellows. 5) Clean the sealing surfaces on the door and tub thoroughly. 6) Fit the new bellows onto the tub lip and secure the inner clamp, then stretch it over the door flange and secure the outer clamp. 7) Reassemble any trim, restore power and water, and run a short test cycle to check for leaks. Follow manufacturer or kit instructions for any model‑specific steps.
How do I ensure a watertight seal after installing the new bellows?
Make sure both mating surfaces (tub lip and door flange) are clean and free of soap residue, debris, and old gasket fragments before installing. Use the correct type and size of clamp and tighten it evenly but not over‑torqued (over‑tightening can deform the rubber). Seat the bellows fully into the grooves at both ends so there are no folds or pinched areas. Run a short rinse cycle and carefully inspect for leaks, and retighten clamps if needed. If the bellows keeps leaking, check for damaged tub flanges, warped door parts, or installation errors.
Where can I buy the 134728400 bellows kit and is there a warranty?
