240457701 Frigidaire Refrigerator Freezer Door closing Cam Stop is a small mechanical cam-and-stop component used in refrigerator and freezer door hinge assemblies to control door travel and final seating. It is a purpose-designed mating surface that limits rotation, provides a defined cam profile for the door to ride over during closing, and establishes the final position that allows the gasket to seal against the cabinet face.
Installed at or near a hinge pivot, the cam stop interacts directly with the hinge pin, hinge bracket and door structure, and indirectly with the door gasket and magnetic seal. During a close cycle the cam profile converts rotational motion into a controlled translation or dwell so the door contacts the cabinet with predictable force and alignment; this prevents over-rotation, reduces shock to the hinge and gasket, and ensures consistent sealing pressure. Because it is part of the door kinematics, its condition affects door alignment, sealing performance, and consequently internal temperature control and defrost behavior.
In this article readers will find a technical examination of the 240457701 cam stop covering its intended function, compatible Frigidaire models and mounting context, common failure symptoms (for example door not closing fully, noisy closing, visible wear or cracked cam surfaces), diagnostic checks and simple troubleshooting steps, and practical replacement considerations such as correct part orientation, fastening method, torque and lubrication recommendations. the guidance is aimed at helping technicians, engineers and informed appliance owners assess condition, determine compatibility, and perform safe, correct replacement when required.

Function and mechanical Role of the Refrigerator Freezer Door Closing Cam Stop
The 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop is a small but precise mechanical stop that defines the final travel position of the freezer door at the hinge. It engages with the hinge cam or strike at the end of the door’s swing to arrest motion, establish consistent gasket compression, and prevent over-rotation or rebound. Because the cam stop sets the seating angle and contact surface for the door, its profile, thickness, and mounting orientation directly affect seal integrity; a worn or incorrectly sized cam stop will allow the door to close out of alignment, resulting in poor sealing, increased run-time, frost buildup, or condensation inside the cabinet. This OEM part is intended as a direct replacement on compatible Frigidaire assemblies, and replacement units must match the original cam profile and fastener positions to maintain the designed door geometry and clearances.
- Common symptoms of a failing cam stop: door that won’t stay closed, noisy or loose closing action, persistent warm spots or frost in the freezer, and accelerated gasket wear.
Mechanically, the cam stop functions as a hard-stop contact that takes intermittent compressive loads during door closure; typical materials are glass-filled nylon or similar polymers chosen for wear resistance and low friction against metal hinge surfaces. Inspect the component for cracking, flattened contact faces, or dimensional loss and verify that the mounting tab and screw hole align with the hinge bracket. During service, verify replacement compatibility by comparing the cam profile, distance from the hinge pivot to the contact face, and screw location to the removed part; minor differences in profile or thickness can shift the door closing angle and require shimming or a different OEM part. When reinstalling, tighten fasteners to secure the cam without distorting the mounting plate, confirm smooth engagement through several open/close cycles, and check gasket compression along the full door edge to ensure the cam stop restored the intended mechanical behavior.

How the 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop Works Inside the Appliance
The 240457701 Frigidaire Refrigerator Freezer Door Closing cam Stop is a small molded cam element fitted to the hinge assembly that establishes the door’s final travel and seating behavior. As the hinge rotates, the cam surface provides a controlled deceleration and positive stop so the door lands squarely against the cabinet gasket and latch. This mechanical interface protects the hinge from over-travel, preserves gasket compression for a reliable seal, and limits shock loads that can loosen fasteners or deform the door frame. Typical construction is an engineering plastic designed for sliding contact; wear appears as flattened lobes, surface glazing, cracks, or enlarged mounting holes that increase play and change the stop position.
Compatibility is defined by the hinge geometry-mounting hole spacing,hinge pin diameter,and cam profile-so replacements must match those dimensions rather than simply the part number. In service, technicians inspect the cam for wear and verify stop position by observing door drift, listening for abnormal impact, and measuring seal compression; replacing the cam stop restores the designed stop point and reduces hinge stress. Common symptoms and speedy checks include:
- Door drifts open or will not remain closed despite an intact gasket.
- Audible slap or inconsistent contact when the door closes (indicating worn cam face).
- Visible play at the hinge or a cam with hairline cracks or flattened lobes.
- Mismatched mounting pattern when attempting to fit an aftermarket cam.

Common Failure symptoms and Diagnostic Indicators of Cam Stop Wear or Misalignment
The door closing cam stop controls the final travel and seating of the freezer door by providing a repeatable contact surface and defined rotational limit at the hinge. The 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop is a molded cam that engages the hinge striker and absorbs closing forces; when the cam’s contact surface wears or the part becomes misaligned on the hinge pin, the door can sit off-center, fail to latch, or close with inconsistent resistance. Wear typically appears as localized polishing, gouges, or a flattened radius on the cam surface, while misalignment shows as an altered engagement angle or asymmetric contact between cam and striker; both conditions change the door’s kinematics and can produce rubbing against the cabinet or torn door gaskets on adjacent edges.
Diagnosing a worn or misaligned cam stop requires a combination of visual inspection and simple functional tests: observe cam-to-striker contact with the door slowly cycled, feel for axial or rotational play at the cam with the door supported, and check door gap uniformity with a straightedge or feeler gauge. Practical indicators that point specifically to the cam stop (rather than hinge pin, striker, or gasket issues) include concentrated wear marks on the cam surface, measurable rotational play at the cam exceeding approximately 2 mm, and restoration of normal seating after temporary repositioning of the cam on the hinge. Typical field symptoms are listed below for quick reference.
- Uneven door gap or visible tilt when door is closed
- Door fails to hold closed or requires extra force to latch
- Audible scraping, grinding, or repeated clicking during closure
- Excessive rotational play or axial looseness at the hinge cam
- Localized wear or deformation on the cam contact surface
| Item | Description |
|---|---|
| Rotational play | Measured movement at cam >2 mm suggests wear or failed retention |
| visible wear | Flattening, gouging, or polished zones on cam contact surface |
| Gap variance | Nonuniform door-to-cabinet gap indicating misalignment |
| Recommended action | Replace 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop when wear or play exceeds thresholds or when realignment does not restore correct seating |
Compatibility, Replacement Considerations, and Step‑by‑Step Installation Procedure for Technicians
The door closing cam stop is the mechanical interface that controls the last 10-20 degrees of door travel, providing a controlled latch point that prevents slamming and ensures an even seal of the gasket. The replacement part 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop engages the hinge cam profile and transfers the closing loads into the hinge mounting rather than the plastic escutcheon; worn or fractured cams will produce symptoms such as incomplete door closure, audible clunks during closing, lateral play at the door edge, and accelerated gasket wear. Confirm compatibility by matching the hinge style and cam geometry to the appliance model: this cam stop is intended for Frigidaire units that use a cam-style hinge assembly (verify the OEM cross-reference and model number on the service sheet before ordering), and orientation (left/right or top/bottom) must match the original to preserve closing direction and travel limits.
When replacing the cam stop, evaluate adjacent components – hinge pin, bushing, mounting screws, and any plastic shims – because cam stop failure frequently coexists with bushing wear or stripped threads that will degrade the new part if not corrected. OEM parts typically maintain tighter dimensional tolerances on the cam radius and bearing surfaces; if using an aftermarket cam, inspect the mating surfaces for proper engagement and test the door sweep and seal after installation. After fitment, perform functional checks: allow the door to close under its own weight through the final sweep, listen for smooth engagement, measure gasket compression across the vertical seal, and check that the door remains latched when subject to light inward pressure (use a 1-2 lb pull test) to confirm correct installation and alignment.
- Disconnect power or secure the unit as required and empty or support the door contents.
- Support the door and remove hinge cover/trim to expose the cam stop and hinge screws.
- Loosen upper hinge fasteners as required and remove the worn cam stop; inspect hinge pin,bushing,and mounting holes for wear or damage.
- Transfer or install the new cam stop with the same orientation; hand-start mounting screws and progressively tighten in sequence to avoid misalignment.
- Reassemble hinge covers, adjust vertical and lateral door alignment as needed, then verify smooth closing, gasket contact, and retention under light force.

Q&A
What is the 240457701 Frigidaire refrigerator freezer door closing cam stop and what does it do?
The 240457701 cam stop is a small hinge-mounted component (often plastic) that controls the final travel and resting position of the freezer door. It acts as a stop and cam surface so the door closes smoothly and stays in the fully closed position rather of swinging back open or overtraveling the hinge.
What are the common symptoms that the cam stop is bad or worn out?
Symptoms include the freezer door not staying fully closed or popping open slightly, a door that over-rotates or hangs, unusual scraping or grinding noises at the hinge, visible cracking or missing pieces on the cam, or uneven door alignment even after adjustment.
How do I confirm that part 240457701 is the correct replacement for my Frigidaire model?
Confirm by checking your refrigerator model number (usually on a sticker inside the fridge or on the cabinet). Then use Frigidaire’s parts lookup, the appliance’s parts diagram in the user manual, or a reputable parts dealer to verify that 240457701 is listed for your exact model. Do not rely on visual similarity alone-cross-reference the model number for a guaranteed fit.
Can I replace the cam stop myself and what safety precautions and tools are needed?
Yes, a competent DIYer or technician can replace it.Required tools are typically a Phillips screwdriver and/or socket set,possibly a flat screwdriver or trim tool to remove hinge covers.Safety: unplug the refrigerator or disconnect power, support the door (have a helper or use a support block) to prevent it from falling when hinge screws are removed, and keep track of screws and washers. Do not overtighten hinge fasteners when reassembling.
What are the basic steps to replace and align the cam stop?
High-level steps: 1) unplug the appliance and support the door. 2) Remove any hinge cover(s) or trim. 3) Loosen or remove the hinge screws to access the worn cam stop. 4) Remove the old cam stop and install the new one in the same orientation. 5) Reinstall the hinge and tighten screws incrementally while checking door alignment and closing action. 6) Test the door through several close/open cycles and make minor hinge/leveling adjustments as needed. Follow your specific model’s service manual for exact instructions.
Should I lubricate the cam stop and what lubricant is safe to use?
If lubrication is recommended (or the cam is dry and making noise), use a food-safe silicone or PTFE-based lubricant sparingly on the cam surface-these are safe around food compartments. Avoid petroleum-based greases (like WD-40 or motor oil) that can degrade plastics and contaminate seals.
What if replacing the cam stop doesn’t fix the door closing problem?
If the door still fails to close properly after replacing the cam stop,check the door gasket for damage or dirt,ensure the refrigerator is level and not overfilled (items blocking door),inspect hinge bearings/shafts for wear,and verify the door liners and shelves aren’t warped or mismounted.If problems persist, the hinge assembly or door might potentially be bent/worn and require further repair or professional service.
Is it better to buy the OEM 240457701 or an aftermarket replacement, and where can I buy it?
OEM (Frigidaire) parts are recommended for fit and longevity because they match factory specifications. Aftermarket parts can be acceptable if they explicitly list compatibility and are of good quality. Purchase from Frigidaire’s official parts store, authorized dealers, or reputable appliance parts retailers online; verify returns and warranty policies before buying.
Insights and Conclusions
The 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop is a small but essential component that helps control the closing motion and alignment of refrigerator and freezer doors. By guiding the door through its final travel and absorbing the mechanical stresses of repeated opening and closing, the cam stop contributes to consistent door seating, helps maintain an effective door seal, and supports overall appliance performance and energy efficiency.
Because wear, deformation, or failure of the cam stop can led to misaligned doors, poor seals, increased cooling load, and accelerated wear on adjacent components, proper diagnosis is vital when symptoms such as uneven closing, unusual noises, or temperature instability are observed.Identifying whether the cam stop-or another element of the door assembly-is the cause ensures that interventions address the root problem rather than masking symptoms or creating further issues.
When replacement is necessary, using the correct OEM part and following manufacturer guidance or engaging a qualified service technician helps ensure reliable restoration of door function and long-term performance. Routine inspection during normal maintenance can detect early signs of wear and help avoid more extensive repairs, preserving appliance efficiency and food safety over the life of the unit.
