240338313 Frigidaire Refrigerator Dairy Door is a molded inner-door accessory designed to form a small hinged compartment within the refrigerator door for storing butter, cheese and other small dairy items.It is a non-electrical, replaceable plastic door assembly that typically includes hinge posts, mounting bosses and the interface features required to secure it to the refrigerator door liner or bin structure.
Within the appliance the dairy door serves as a localized enclosure that limits direct exposure of sensitive dairy products to warmer air that enters when the main door is opened, and it contributes to interior association by providing a dedicated, accessible bin. Mechanically it interfaces with the door inner liner or shelf system via snap-fit clips or screws and with adjacent door bins; its condition can affect door closure, create stress points on hinge posts, and influence local airflow patterns caused by the refrigerator’s evaporator fan and door opening dynamics.
In this article you will find a technical overview of the dairy door’s function and construction, guidance on verifying compatibility with specific Frigidaire models, common failure symptoms (cracked or broken hinge posts, loose or missing mounting features, interference with door closure), step‑by‑step troubleshooting checks to isolate mechanical faults, and practical replacement considerations such as required tools, fitment checks, and installation precautions to restore correct operation without affecting adjacent door components.

Function and Role of the Dairy Door in temperature Control, Storage Access, and Door Seal integrity
240338313 Frigidaire Refrigerator Dairy Door functions as a small, enclosed access panel on the inner door that stabilizes a microclimate for butter, cheese, and other dairy items. By isolating a limited volume from the refrigerator’s main cavity it reduces convective air exchange and limits humidity transfer during door openings, wich helps maintain a more consistent surface temperature for stored items and reduces transient load on the refrigeration system. The part is a molded thermoplastic assembly with integrated hinge tabs and snap-fit bosses that must align precisely with the door housing to form the intended mating surface and maintain seal geometry.
- Primary behaviors: isolates volume,minimizes air exchange during door opens,and serves as a precision mounting interface for small food containers.
- Key compatibility/fit criteria: matching tab pattern, boss locations, and lip profile to the specific inner door cavity.
- Common failure modes and symptoms: cracked hinge/tab, warped sealing lip, or loose fit leading to condensation, frost buildup, or warmer-than-expected items in the compartment.
| Item | Description |
|---|---|
| Material / construction | Molded thermoplastic (commonly ABS or polypropylene) with molded hinge tabs and sealing lip. |
| Mount interface | Snap-fit bosses and hinge tabs that rely on correct alignment to maintain seal integrity. |
| Diagnostic sign | Check for visible gaps with a flashlight or a straightedge; condensation or softened butter point to compromised seal or damaged tabs. |
For technicians and owners,practical inspection includes verifying that all hinge tabs are undamaged and that the sealing lip contacts the door housing continuously when closed; a missing or broken tab commonly allows a small gap that accelerates moisture exchange and frost. When replacing the assembly match the mounting geometry and verify the part engages with an audible click on installation; if the sealing lip shows permanent deformation replace the entire dairy door rather than attempting a local repair, because the lip profile controls airflow and humidity behaviour more than surface cleanliness or appearance.
How the 240338313 Frigidaire Refrigerator Dairy Door Operates Within the Door Assembly and Seal interface
The 240338313 frigidaire Refrigerator Dairy Door is a hinged inner-panel designed to sit flush within the main door liner and form a small cold-storage compartment. It mounts on pivot pins or molded bosses and engages a continuous gasket channel on the door liner; when closed, the molded gasket lip compresses into the liner flange to create the seal interface that limits convective air exchange. Proper function depends on correct alignment of the hinge pins and retention clips so the gasket achieves uniform compression across the mating surface rather than rubbing or leaving gaps that promote heat ingress or moisture migration.
In normal operation the dairy door should move smoothly on its hinge and return to a fully seated position without leaning or binding; common wear points are the hinge boss and the gasket bead, which can deform or abrade from repeated operation. Technicians inspecting a unit should look for uneven gasket compression, visible gaps, frost or condensation behind the dairy door, and loose mounting hardware as indicators of a compromised seal. For repair or replacement, ensure the replacement door matches the liner recess geometry and that the hinge pins are installed to allow the door to compress the gasket by the manufacturer-specified amount rather than forcing it, which can accelerate wear.
- checkpoints: hinge play, gasket seating, uniform contact pressure, absence of rubbing against door bins
- Symptoms of failure: localized frost, audible air leakage when closing, difficulty latching, visible gaps
- Practical action: realign hinge pins, replace torn gasket, verify clearance with internal shelves
| Item | Description |
|---|---|
| Material | Rigid thermoplastic (common ABS or polypropylene) inner panel with molded gasket |
| Mounting | Pivot pins or molded hinge bosses with retention clips inside door liner |
| Seal type | Molded gasket lip compressing into liner flange to form an air barrier |
| Common failure mode | Hinge wear or gasket deformation causing uneven compression and air leakage |
Common Failure Symptoms: Seal Leakage, Hinge/Retention Wear, cracking, and Insulation Loss
The 240338313 Frigidaire Refrigerator dairy Door is a molded interior door that covers the dairy shelf and provides a localized seal and modest thermal barrier inside compatible Frigidaire refrigerator models. As a small assembly it combines a retaining hinge/clip interface, a sealing lip, and hollow or foam-filled sections that contribute to rigidity and insulation; proper fit with the cabinet liner and functioning retention tabs ensures the door closes with the designed compression on the gasket and minimizes air exchange between the compartment and the fresh-food cavity.
- Seal leakage: compressed or torn sealing lip that allows cold air to escape, increasing compressor runtime and causing frost or condensation near the joint.
- Hinge/retention wear: worn pins or cracked tabs that produce play or permit the door to remain ajar under load.
- Cracking: visible fractures in the skirt or mounting ears that lead to loss of alignment and intermittent sealing.
- Insulation loss: collapse or voids in foam cores that reduce thermal resistance and create cold spots or higher compartment temperatures.
Technicians can diagnose failures by inspecting the mating surfaces for continuous gasket contact, checking for lateral play at the hinge points, and looking for hairline cracks at high-stress areas such as clip ears. Practical checks include closing the door with a thin card to test seal compression, comparing compartment temperatures with a probe thermometer before and after replacing the dairy door, and applying light torque to retention tabs to assess fatigue; if the gasket cannot achieve consistent compression or the mounting tabs fracture under modest inspection force, replacement of the 240338313 Frigidaire Refrigerator dairy Door is warranted to restore sealing and thermal performance.

Replacement Considerations and Installation Procedure: Compatibility, Fasteners, Seal Alignment, and Torque Specifications
The 240338313 Frigidaire Refrigerator Dairy Door functions as a sealed, movable compartment door that maintains a micro-environment for dairy items by compressing a gasket against a smooth cabinet flange. Verify part compatibility against the refrigerator model and the inner-door mounting geometry before replacement; match hinge boss spacing, mounting-post diameter, and the gasket groove profile because replacement doors with diffrent boss locations or groove widths will not seat or seal correctly. The dairy door’s performance depends on proper seal compression and hinge geometry: a misaligned door increases air infiltration,causes temperature drift in the compartment,and can produce condensate or frost at the seal interface.
During installation, use correct fastener types, preserve the original cam/stop orientation, and set fastener torque to maintain consistent gasket compression without deforming plastic bosses. Typical procedures include supporting the door to avoid stressing hinge bosses, hand-threading screws to prevent cross-threading, aligning the gasket so its flat sealing face contacts the cabinet flange uniformly, and cycling the door to seat the gasket before final torque. After installation, verify even seal contact around the perimeter and confirm the compartment holds temperature under a normal load; if uneven compression is observed, incremental adjustments to hinge position or shimming the gasket might potentially be required.
- Remove old door and inspect hinge bosses, mounting posts, and gasket groove for damage.
- Hand-fit the 240338313 Frigidaire Refrigerator Dairy Door and check orientation and seal engagement before torquing fasteners.
- Torque fasteners in a cross-sequence to specified values, then cycle door to seat gasket and re-check contact.
- Perform a final visual and tactile check for continuous seal compression; run a temperature verification after 24 hours of normal operation.
| Item | Description |
|---|---|
| Hinge screws (sheet-metal or machine) | Torque to 6-8 in·lb to clamp without crushing plastic hinge bosses; confirm manufacturer fastener type. |
| Retaining/trim screws | Torque to 8-10 in·lb to hold seal trim and cam stops; avoid overtightening which distorts the gasket. |
| Adjustable cam/stop | Set for even gasket compression; final seating verified by continuous contact, no visible gap under normal lighting. |
