240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop is a small mechanical component used in the door hinge and closure assembly of Frigidaire refrigerators. It is typically a molded cam/stop element (often made from engineering plastics such as nylon or acetal, sometimes combined with metal inserts) that interfaces with the hinge or striker to control door rotation and final seating position rather than an electrical or electronic part.
Within the appliance, the cam stop limits door travel, provides a defined stop or detent for the closing motion, and helps align the door gasket to produce a reliable seal. It directly interacts with the hinge pin, striker plate, door frame and gasket seating surface; indirectly, proper operation affects evaporator load and compressor run time as a poorly closing door permits cold-air loss and frost accumulation. Mechanically, the cam profile converts rotational movement of the hinge into a controlled stopping action and, depending on design, can provide partial damping or a holding position to prevent bounce or over-travel.
In this article readers will find a technical description of the 240457701 cam stop’s function and how it integrates with the hinge and sealing system, guidance on model compatibility and how to verify that the part number matches a given appliance, common failure symptoms (for example misalignment, excessive play, door not closing or slamming, icing or elevated compressor duty), troubleshooting steps to isolate the cam stop from other hinge or gasket issues, and practical replacement considerations such as required disassembly, door support, inspection of mating components, and criteria for replacing the cam stop versus the entire hinge assembly.

Function and Role of the Door-Closing Cam Stop in Refrigerator Door Alignment and Seal Integrity
The 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop is a small cam-shaped component installed on the door hinge assembly that controls the final travel and seating of the door. Mechanically, the cam stop converts hinge rotation into a controlled lateral motion that pulls the door into the strike and sets the gasket compression. Properly sized and located cam stops maintain repeatable door alignment and even gasket contact pressure across the sealing surface; worn, cracked, or incorrectly matched cam stops allow over-travel or under-seating of the door, producing gaps, uneven wear on the gasket, and measurable cold-air leakage. This part is designed for specific Frigidaire hinge geometries and should be matched to the refrigerator’s hinge style and side (left/right) rather than assumed to be global.
Technically, the component rides on a hinge pin and typically is molded from wear-resistant plastic or composite; its performance depends on tolerances at the pin bore and the cam profile. Replacement procedures require removing the hinge fasteners, verifying orientation and engagement with the mating strike, and re-torquing hinge hardware to specified values to avoid introducing new alignment errors. In practical service, technicians often restore seal integrity by replacing the cam stop and then making small hinge or shim adjustments to equalize gasket compression; if the gasket remains uneven after correct cam stop replacement, further hinge or cabinet adjustments are indicated rather than repeated cam changes.
- Common symptoms of a failing cam stop: door sag, visible gap at one edge, uneven gasket compression, increased run time or frost buildup in the compartment.
- Basic checks: inspect cam for cracking or wear, confirm correct part orientation, measure door vertical alignment before and after replacement.
- Installation notes: verify model compatibility and left/right designation, lubricate hinge pin lightly if specified, and follow torque specifications when reassembling.

How the 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop Integrates with Hinges, Latching Assemblies, and Door Movement Mechanics
The 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop is the small but critical contact element that controls the final rotation and indexing of the freezer door relative to the hinge and latch assemblies. Positioned at the hinge cup or lower hinge, the cam stop’s ramp and face geometry arrests the door at a repeatable angle, transfers closing loads into the hinge bracket, and establishes the engagement point for the latch striker so the gasket achieves the designed compression. When the cam profile wears or the part is installed incorrectly, the door can over-rotate or under-engage the latch, producing door sag, incomplete sealing, or excessive stress on hinge pins and the latching assembly.
Integration with the hinge and latching systems requires attention to mating surfaces, alignment, and lubrication.The cam stop works in concert with hinge bushings and the latch striker: correct vertical and rotational alignment of the cam relative to the hinge axis ensures consistent sealing forces and prevents lateral play that would overload the latch. During service,technicians should inspect the cam stop face for flattening,check hinge pin runout,and verify that the striker contacts the cam at the intended point of the ramp; a thin,non-petroleum lubricant on the pivot and cam-contact area can reduce wear without attracting debris. Practical troubleshooting examples include replacing the cam stop when repeated hinge pin replacements fail to eliminate a leaking seal, and re-indexing the cam by shimming or rotating the hinge assembly to restore proper latch engagement.

Diagnostic Indicators and Common Failure Symptoms of a Worn or Damaged Door Closing Cam Stop
The 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop is a small but critical hinge cam that defines the final closed position of the freezer door and provides a repeatable engagement surface for the cabinet strike. It functions as a mechanical stop that limits door rotation, aligns the gasket contact area, and absorbs closure forces to prevent rebound. In service the cam is commonly molded from an engineering plastic pressed onto a pivot pin; failure modes include abrasion of the cam nose, cracking or chipping of the material, and enlargement of the mounting hole or pivot bore, any of which allow excess play and inconsistent sealing.
Diagnosis combines visual inspection with simple functional checks: observe the cam and strike for visible wear, operate the door slowly to feel for rough engagement or backlash, and note refrigeration symptoms like persistent warm spots, frost buildup, or faster-than-normal compressor cycles that indicate an intermittent seal. Common observable symptoms include:
- Incomplete seal / gap at top or bottom: door stops short of the gasket contact surface and requires lifting or additional force to close, often due to a worn cam face.
- Bounce or rebound on closing: worn cam geometry lets the door overtravel and then spring back off the strike,causing noisy operation and air exchange.
- Intermittent door latch engagement: loosened pivot or elongated hole permits the cam to shift out of position under load,producing inconsistent behavior between cycles.
- Visible damage or material loss: chips, flattened profile, or cracking at the cam nose that directly compromise stopping action.

Replacement Considerations, Model Compatibility, and Step-by-Step Installation Guidance for Frigidaire Cam Stop Assemblies
The 240457701 Frigidaire Refrigerator Freezer Door Closing Cam Stop functions as the mechanical limit and indexing element on the hinge assembly that controls how the freezer door stops and settles against the cabinet. it converts the rotational motion of the hinge into a defined stop position so the door gasket compresses uniformly; wear, cracking, or deformation of the cam profile or mounting boss will change closing geometry and can produce air leaks, uneven gasket compression, or a door that either latches too early or slams past the intended stop. Compatibility is resolute by hinge geometry, boss diameter, mounting hole spacing, and cam profile; technicians should compare the replacement cam stop to the removed part and consult the appliance parts list or service manual to confirm fit before installation.Such as, a cam stop that matches the mounting hole pattern but has a different cam radius can still produce a misaligned seal and require hinge shimming or a different OEM part rather than a direct swap.
- Disconnect power and remove any door panels or trim needed to access the upper hinge and cam stop; support the door so it cannot shift when fasteners are removed.
- Remove the retaining screw(s) while noting the cam orientation and any locating pins; retain hardware and inspect the hinge boss for wear or cracks.
- Compare new cam stop to the old one – verify mounting hole spacing, cam profile, and boss diameter – then position the replacement and hand-thread the fastener(s) before final tightening.
- Secure fasteners to a firm snugness without over-torquing plastic bosses; if manufacturer torque is unavailable, avoid excessive force and check that the cam engages smoothly through the full door travel.
- Reinstall trim and test by closing the door slowly; check gasket seal, alignment, and repeatability over several cycles. If the door still binds or gaps persist, inspect hinge bearings and consider replacing the hinge assembly rather than only the cam stop.

Q&A
What is the 240457701 Frigidaire Refrigerator Freezer Door Closing cam Stop and what does it do?
The 240457701 is a refrigerator/freezer door cam stop (also called a door stop or cam) used on certain Frigidaire/Frigidaire Gallery/Kenmore refrigerators. It sits at the hinge area of the freezer or refrigerator door and controls the final travel of the door, helping it engage the hinge correctly and preventing the door from over-rotating or hanging. It helps the door close smoothly and maintain proper alignment and seal.
How can I tell if the cam stop is bad or needs replacing?
Common symptoms of a failing cam stop include a door that won’t close fully, a door that catches or has uneven travel, visible cracks or wear on the cam, or the door sagging on one side.You can visually inspect the cam stop for damage and check for excessive play at the hinge while the door is open and closed. If the cam is worn,broken,or missing pieces,replacement is recommended.
Which Frigidaire models use part number 240457701 and how do I confirm compatibility?

Do not rely solely on appearance-use the model number cross-reference.
Can I replace the cam stop myself? What tools and steps are required?
Yes, many owners can replace this cam stop with basic tools. Typical tools: Phillips screwdriver,socket or nut driver set (frequently enough 1/4″ or 5/16″),and a putty knife or trim tool to remove hinge covers.Basic steps: unplug the appliance or disconnect power; support the door so it won’t fall (use a helper or a block); remove hinge cover(s); unfasten hinge or retaining screws to access the cam stop; remove the old cam and install the new one in the same orientation; reassemble and tighten hinges, then check door alignment and seal. Do not overtighten hinge fasteners; adjust as needed so the door closes and seals properly.
Are there any safety precautions I should follow when replacing the cam stop?
Yes. Always disconnect power to avoid electrical hazards if working near lights or wiring. Support the door to prevent it from falling-hinge bolts can release the door suddenly. Wear gloves and eye protection for hand and eye safety. Keep track of screws and small parts so the hinge can be reassembled correctly. If you are unsure about supporting or reinstalling the door,get a second person or a technician to help.
How long does replacement take and what is the typical cost for the part?
Replacement usually takes 20-60 minutes for a competent DIYer, depending on access and whether the door must be removed. The OEM cam stop part typically costs in the range of about $10-$35 (prices vary by retailer and region). If you hire a technician, add labor costs, which can vary widely.
Should I buy an OEM part or is an aftermarket cam stop acceptable?
OEM (Frigidaire-branded) parts are recommended for exact fit and material quality, which helps ensure proper alignment and longevity. Quality aftermarket parts can work and are often less expensive, but check reviews and confirm fitment for your model. Avoid low-quality imitations that use brittle plastic or incorrect dimensions-those can fail quickly and cause door alignment issues.
After installing a new cam stop, how do I check and adjust the door alignment and seal?
After reassembly, open and close the door several times to confirm smooth operation and that the door stops at the correct point. Check the gasket seal by placing a piece of paper between the gasket and cabinet at multiple points and closing the door-there should be slight resistance when you pull the paper out. If the door is misaligned, slightly loosen the hinge screws, reposition the door, and retighten. Make small adjustments and recheck the seal until satisfactory. If problems persist, inspect hinges and other mounting hardware for wear or damage.
