Diagnosing a refrigerator that refuses to cool or repeatedly clicks off within seconds of powering on requires identifying whether the electrical starting components or the motor pump itself has failed. Refrigerators rely on a delicate sequence of electrical signals where the compressor motor draws high amperage at startup, assisted by a run or start capacitor and managed by a start relay. If that relay or its companion thermal overload protector burns out, the compressor will fail to turn over, resulting in warm interior temperatures while the fans and interior lights continue to operate normally. When the motor windings internally seize or the mechanical pump fails, a simple electrical swap will not resolve the issue, demanding a full compressor swap instead.

Because Kenmore contracts multiple manufacturers to build its appliance catalog, the Kenmore refrigerator compressor components on the market are organized by specific production lineages rather than universal fittings. Whirlpool-built Kenmore units commonly rely on TSD2 or push-on modular start relays paired with rectangular run capacitors, whereas LG-built Kenmore units typically utilize specialized three-pin thermal overload protectors and linear compressor assemblies. Third-party replacement components match these distinct engineering lineages through exact cross-reference part numbers and electrical ratings, making model verification the single most critical step before beginning any refrigerator repair.

• Durable copper contact material
• Broad cross-reference part replacement

Cons

• Mounting type not specified in listing

The W10613606 Refrigerator Compressor Start Relay is supplied as a paired combination containing one replacement start relay and one auxiliary CBB61 run-assist start capacitor rated at 15uF plus or minus five percent at 250VAC. Unlike the TSD2 configuration, this electrical interface operates on a normally open contact design with copper contacts, carrying a coil voltage rating of 250 volts alternating current. The components feature screw connector terminals that seat onto the compressor terminal pins, routing current to the motor windings to initiate rotor movement during startup cycles. While smaller cooling setups like a dometic 12v refrigerator rely on dedicated low-voltage solid-state control boards, domestic household appliances rely on this exact style of high-voltage kenmore refrigerator start relay assembly to manage the initial inrush current.

The listing outlines a critical compatibility warning: possessing the same replacement part number does not guarantee universal operation with every compressor or cabinet layout. Refrigerator owners must cross-reference both the cabinet model tag and the compressor manufacture label prior to installing this w10613606 start relay kit. The part replaces numerous established factory numbers, notably W10416065, PS8746522, 67003186, AP5787784, EAP8746522, 67003764, 67005560, and 8208290 across Kenmore, Whirlpool, Amana, and Jenn-Air appliances.

When the original solid-state relay inside the housing fractures from thermal degradation, the refrigerator will experience identical symptoms to motor lockup, including warm food compartments and failure to initiate a cooling pass. Swapping in this durable replacement eliminates the resistance bottlenecks caused by burned original terminals. The package provides two individual items in the box, giving technicians and homeowners both the inductive relay module and the matching 15uF capacitor necessary for restoring balanced phase angles during startup.

Because it replaces the central hermetic pump, installing this assembly requires extensive sealed-system refrigeration work, contrasting sharply with the simple push-on terminal installation used for modular accessories like a frigidaire replacement icemaker.

This replacement compressor directly targets catastrophic refrigeration system failure, where the appliance maintains interior lighting and fan circulation but exhibits zero heat rejection at the condenser coil and zero cooling within the evaporator. Weighing sixteen ounces according to shipping records, the assembly comes out of the box ready for professional braze-in installation, vacuum evacuation, and accurate refrigerant charging. For owners facing a condemned appliance due to an unstartable or mechanically seized LG-line Kenmore compressor, this targeted core component allows the sealed system to be fully rebuilt to original operational capacity.

04 6750CL0001D 3-Pin Refrigerator Compressor Overload Protector Features 3-Pin terminal configuration, consistent with original part

Check price on Amazon 3.8 out of 5 — average from Amazon buyers

Best for: Kenmore LG models needing 3-pin overload protection

Pros

• Precise 3-pin socket configuration
• Direct thermal and current monitoring
• Durable copper internal terminals

Cons

• Includes overload protector only, no relay

The 6750CL0001D 3-Pin Refrigerator Compressor Overload Protector is a dedicated thermal safeguard designed specifically for Kenmore and LG bottom-mount and side-by-side refrigeration platforms. Manufactured with copper contacts and housed in a heat-resistant socket-mount chassis, this kenmore compressor overload protector features a three-pin terminal configuration designed to match factory interface dimensions and terminal spacing on compatible compressor headers. Operating in an automatic, normally closed configuration, the overload sits directly inline with the incoming power path feeding the compressor motor windings.

The core operating principle outlined by the manufacturer involves continuous current and temperature sensing. The 6750cl0001d overload protector mounts directly against the exterior casing of the refrigerator compressor, monitoring the motor electrical current draw. If internal resistance surges or the compressor struggles against high head pressure, the internal bimetallic strip heats rapidly, automatically cutting off the electrical supply before the motor windings experience catastrophic thermal breakdown. Once normal operating temperatures return, the automatic switch re-establishes contact.

This protective component substitutes directly for part numbers AP5331981, 2651363, AH3603394, EA3603394, and PS3603394. If your Kenmore refrigerator repeatedly starts for three to five seconds, produces a pronounced metallic click, and immediately drops offline, the existing three-pin protector has likely degraded from repeated thermal cycling. Installing this single-count replacement component restores the critical current protection boundary, ensuring reliable automated safety without requiring the replacement of an undamaged compressor motor.

Before You Buy

The replacement components in this guide do not include universal installation hardware, auxiliary wire harnesses, or replacement copper tubing. When purchasing modular relays and overloads, the listings supply only the specific electrical switch or capacitor described, requiring you to reuse your existing compressor terminal bail wire, protective plastic cover, and mounting bracket. Furthermore, the product data does not specify individual wire color codes or supply custom wiring diagrams for every cabinet permutation, meaning you must carefully document the exact terminal connections on your original parts prior to removal.

For the complete compressor assembly, the listing does not include the essential supplies demanded for hermetic refrigeration work, such as replacement filter driers, process access valves, recovery equipment, vacuum pumps, or the specific refrigerant charge required by your cabinet rating plate. Rebuilding a sealed system demands specialized HVAC/R recovery certifications and brazing tools that fall far beyond standard electrical relay replacements. Always confirm your Kenmore cabinet’s complete model and serial tag—paying special attention to whether the prefix denotes Whirlpool (such as 106) or LG (such as 795) manufacturing—before ordering any replacement hardware.

FAQ

How do I know if I need a start relay or a complete Kenmore refrigerator compressor?

When a refrigerator clicks every few minutes without the compressor ever running, the issue is almost always a burned start relay or overload protector. The relay can be removed and gently shaken; a distinct rattling sound indicates that the internal solid-state wafer has shattered. If the start relay tests fine for continuity and supplies voltage, but the compressor draws excessive locked-rotor amperage or hums without pumping, the compressor motor has suffered mechanical failure and requires full replacement.

Can I use the 2319792 overload and relay on any Kenmore refrigerator compressor?

No, the product specification sheet explicitly notes that if your compressor rating exceeds 1/4 horsepower, this assembly will not work. Additionally, this TSD2-style relay is designed specifically for compatible Whirlpool-built electrical architectures and cannot mount to the three-pin configurations found on LG-built compressor bodies.

What does the 6750CL0001D overload protector do on a refrigerator?

The 6750CL0001D mounts directly against the compressor housing to monitor current draw and case temperature. If the motor encounters elevated resistance or voltage spikes, the normally closed internal contact snaps open to cut power, preventing permanent destruction of the motor windings. Once the component cools down, it resets automatically.

Why does the W10613606 listing warn that same part numbers do not guarantee compatibility?

Appliance manufacturers frequently switch production suppliers across model years while utilizing similar electrical schematics. A compressor might require specific terminal spacing, different pin positions, or alternative run capacitor capacitance. Checking both your cabinet model number and the manufacturer plate directly on the compressor body ensures that the physical terminal block and electrical load match the replacement assembly.

Which Kenmore compressor part to buy for LG-manufactured Kenmore models?

Kenmore refrigerators with model numbers beginning with the 795 prefix originate from LG production. For these cabinets, electrical thermal failures are resolved using the 6750CL0001D 3-pin overload protector, whereas total internal mechanical breakdowns require the TCA38091801 / CKD091801X compressor assembly. Whirlpool-style relays like the TSD2 or 61005518 will not match the terminal pin layout or mounting interface on these units.
