W10160407 Whirlpool refrigerator Compressor is a sealed refrigeration compressor assembly used in certain Whirlpool refrigerator models too compress and circulate refrigerant thru the appliance’s sealed cooling loop. As a rotating mechanical/electrical device,it contains the motor and compression mechanism (typically housed in a hermetic shell),electrical terminals for start and run circuits,and connections for the suction and discharge refrigerant lines. Technicians will recognize it as the primary pressure-generating component in the refrigeration circuit, mounted at the rear or base of the cabinet and frequently enough accompanied by a start device and overload protector.
Inside the appliance, the compressor’s role is to raise refrigerant pressure and temperature on the discharge side so that heat can be rejected at the condenser, then allow pressure to drop through expansion and evaporation in the evaporator to absorb heat from the cabinet. It interacts directly with the condenser, evaporator, capillary or expansion device, refrigerant lines, and associated controls (thermostat or electronic control board), and indirectly with fans and defrost systems that affect heat exchange. Proper mechanical mounting, vibration isolation, correct electrical supply, and compatibility with the installed refrigerant and oil are all critical to reliable operation and system balance.
In this article readers will find a technical overview of the W10160407 compressor’s function and typical specifications, guidance on verifying compatibility with specific refrigerator models, common failure symptoms and diagnostic checks (electrical, mechanical, and refrigerant-circuit indicators), step-by-step troubleshooting suggestions, and practical considerations for replacement or service-such as refrigerant recovery, oil and refrigerant matching, correct mounting and electrical connections, and the need to inspect related components (start relay, overload, and system seals). The intent is to equip technicians, engineers, and informed appliance owners with the context and procedures necessary to evaluate, diagnose, and plan safe service or replacement of this compressor.

Functional Role of the Compressor in the Refrigerator’s Sealed Refrigeration Cycle
The sealed refrigeration cycle depends on the compressor to convert low-pressure refrigerant vapor from the evaporator into a high-pressure, high-temperature vapor that the condenser can reject to ambient. The W10160407 Whirlpool Refrigerator Compressor functions as a hermetic displacement pump: an electric motor inside the sealed shell drives a piston or scroll element to raise refrigerant pressure and temperature, maintain refrigerant flow against system pressure drops, and circulate oil for lubrication. In operation the compressor must match the system’s refrigerant type, volumetric displacement and electrical requirements; mismatched displacement or incorrect electrical characteristics will alter head and suction pressures, reduce cooling capacity, and can overstress the motor or other sealed-system components.
Technically, the compressor’s steady-state behavior and transient responses determine system performance and diagnostic approach. Measured parameters for technicians include suction and discharge pressure,current draw at start and run,and temperature differences across the evaporator and condenser; abnormal signs-excessive running temperature,high head pressure with little cooling,or a humming motor that will not start-point to mechanical failure,restriction,or electrical faults. Practical service steps include verifying correct line voltages, checking for system restrictions or non-condensables, and ensuring proper evacuation, refrigerant charge and oil type if replacing the compressor; compressor replacement without recovery and evacuation of the refrigerant risks contaminating the system and voiding performance.
- Primary roles: pressurize refrigerant vapor, enable heat rejection, circulate oil, and overcome pressure drops.
- Operational parameters: start current, running current, volumetric displacement, and thermal behavior.
- Service considerations: compatibility with refrigerant/oil, electrical rating, mounting footprint, and required evacuation procedures.

How the W10160407 Whirlpool Refrigerator Compressor Works Within the Appliance’s Refrigerant Circuit and Electrical System
the W10160407 Whirlpool Refrigerator Compressor operates as the sealed mechanical pump in the refrigerator’s refrigerant circuit, taking low‑pressure vapor from the evaporator, compressing it to high pressure and delivering it to the condenser. Internally this type of unit combines the compression mechanism and an electric motor within a hermetic shell and circulates lubricating oil with the refrigerant to protect bearings and valves. In the installed system it mounts directly to the refrigerant tubing between evaporator and condenser and interfaces electrically through a set of run/start terminals and a thermal overload or start device (which might potentially be external). Compatibility with the appliance depends on matching the compressor’s displacement, mounting, and the refrigerant/oil chemistry and pressures specified by the manufacturer rather than on cosmetic similarities alone.
Electrically and behaviorally the compressor cycles on thermostat demand and exhibits a high inrush current at startup followed by a steady running current; proper operation requires correct supply voltage,an appropriate start relay or PTC element,and a functioning overload protector. technicians replacing or diagnosing a failed unit should confirm terminal pinout, mounting orientation and refrigerant charge match the original design-mismatches can cause hard starts, reduced cooling capacity, excessive noise, or repeated tripping of protective devices. Practical field indicators of compressor or compatibility issues include inability to start (clicking relays, no current flow to motor), continuous short cycling, and abnormal discharge temperatures or pressures.
- Suction → compression → discharge sequence is continuous while the motor runs.
- Start devices and overloads manage inrush and prevent motor overheating.
- Oil return and refrigerant charge must be correct to maintain lubrication and heat transfer.

Common Failure Symptoms: Electrical, Mechanical and Performance Indicators of Compressor Fault
The W10160407 Whirlpool Refrigerator Compressor is a hermetic, single‑phase motor-compressor that provides the pressure differential necessary for refrigeration; its electrical health is therefore the first place to look when troubleshooting. electrical failure indicators include repeated rapid clicking from the relay, a compressor that fails to start despite line voltage, unusually high current draw on the run winding, or an open/shorted winding found with an ohmmeter. these symptoms point to problems with the start device (relay or PTC), degraded windings, or intermittent connections in the compressor terminals rather than refrigerant charge issues, and they can be confirmed with a clamp ammeter, continuity checks, and inspection of the start relay and capacitor circuits before considering compressor replacement.
Mechanical and performance indicators reveal internal compression or lubrication faults: a compressor that runs continuously but the cabinet temperature rises suggests loss of compression from failed valves or internal leaks, while pronounced knocking, grinding, or excessive vibration suggests internal mechanical wear or broken motor bearings. other practical signs include oil residue at the service port or on the base (possible hermetic seal failure), elevated discharge temperatures, or repeated long run cycles with minimal temperature change. For field diagnosis, compare measured electrical values to service specifications, observe cycling behavior under load, and correlate noise/vibration patterns with mechanical failure modes to determine whether the W10160407 requires component-level service (starter/relay) or full replacement.
- No start / clicking: Faulty start device or open start winding.
- High current draw: Stalled rotor, shorted windings, or excessive mechanical load.
- Continuous run with warm evaporator: Internal loss of compression or refrigerant flow restriction.
- Excessive noise/vibration: Internal mechanical failure or loose mounting.
- Oil leakage or scorch smell: Hermetic breach or thermal damage to windings.
| Item | Description |
|---|---|
| Electrical test | Measure run and start winding resistance, check relay continuity, and record running current against nameplate/service data. |
| Performance sign | Continuous operation with inadequate cooling indicates internal valve or compression failure rather than a simple refrigerant leak. |
| mechanical symptom | Knocking or metallic noise typically correlates with internal component wear or bearing failure; replacement is normally required. |
Replacement Considerations,Model Compatibility and step‑by‑Step Installation Requirements
The W10160407 Whirlpool Refrigerator Compressor is a sealed refrigeration compressor whose primary function is to compress low‑pressure refrigerant vapor into high‑pressure vapor so the system can reject heat at the condenser. For a replacement,technicians must match physical and functional characteristics: the mounting footprint and port orientation must align with the cabinet and tubing,the compressor’s electrical ratings and starting device must be compatible with the existing line voltage and control board,and the compressor oil must be compatible with the system refrigerant. Symptoms that indicate a compressor swap rather than ancillary repair include locked‑rotor current well above rated amperage, continuous tripping of overload devices, or mechanical noise consistent with internal failure rather than refrigerant restriction.
Practical installation requires proper refrigerant recovery and controlled brazing or use of service valves to avoid contamination; the replacement should be brazed using silver‑bearing alloy and a nitrogen purge to prevent oxidation. After replacing the unit, evacuate and hold vacuum to factory‑level deep vacuum, charge with the correct refrigerant and oil quantity, and verify operating parameters: running current, high/low side pressures, and calculated superheat/subcooling to ensure correct charge and heat transfer.Electrical isolation, vibration isolation pads, a new drier/filter and a compatible start relay/overload assembly (if external) are typical procedural requirements to ensure reliable operation and compliance with service standards.
- Pre‑replacement checks: model cross‑reference, refrigerant type, oil compatibility, mounting and port orientation.
- Service steps: recover refrigerant → disconnect electrical → remove old compressor → purge and braze new connections → evacuate → charge → run and verify pressures/amps.
- Post‑install tests: locked‑rotor amp,running amp,suction/discharge temp and pressure,leak test,and vibration/noise inspection.
| Item | Description |
|---|---|
| Electrical | Match line voltage, rated running and locked‑rotor currents, and ensure compatible start device or relay. |
| Refrigerant / Oil | Replace with same refrigerant type and use oil compatible with that refrigerant and the compressor lubricant spec. |
| Mounting & Connections | ensure identical mounting footprint, correct suction/discharge port orientation, and use nitrogen during brazing to prevent oxidation. |
| Service Requirements | Recover refrigerant, deep vacuum to remove moisture, install new drier, charge to manufacturer specifications, and verify system performance. |
Q&A
What exactly is part W10160407 and how do I confirm it’s the correct part for my Whirlpool refrigerator?
W10160407 is an OEM Whirlpool part number associated with the refrigerator compressor assembly used on specific Whirlpool/Maytag/KitchenAid models. To confirm it’s the correct part for your appliance, first record your refrigerator’s model and serial number (usually on a sticker inside the cabinet or on the rear panel), then cross‑reference that model with Whirlpool’s parts diagram or a trusted parts retailer. Also check the compressor label in the back of the fridge for the same part/manufacturer information. Don’t rely on appliance appearance alone-use the model cross‑reference to ensure compatibility.
What are common symptoms that indicate the compressor (or W10160407) is failing?
Typical signs of compressor problems include: the compressor not starting (fridge gets warm), continuous humming or clicking without cooling, fridge cycles rapidly, unusual loud noises from the compressor (clanking or grinding), and tripped breakers. Bear in mind other failures (start relay, overload, sealed system leak, thermostat, or control board) can produce similar symptoms, so verify compressor failure with tests before replacing it.
How can I test the compressor to determine if W10160407 is bad?
First disconnect power. Remove the start relay/overload and inspect for burn marks or a burnt smell. Use a multimeter to check continuity between the compressor terminals: for a three‑terminal compressor the resistance between Common‑Start,Common‑Run and Start‑Run should show finite resistances and the Start‑Run should equal the difference between the other two (the exact ohm values vary by model). Also check for a short to ground (low/no resistance between any terminal and the compressor case) which indicates failure. If the compressor hums but won’t start,test or swap the start relay/capacitor where applicable-often the problem is the start device,not the compressor. If still unsure, a technician can perform a locked‑rotor amp test and other diagnostics.
Can I replace the compressor myself and what tools/skills are required?
Compressor replacement involves refrigerant recovery, brazing copper lines, vacuuming the sealed system, charging with the correct refrigerant and oil, and electrical reconnections. Because refrigerant handling and pressure testing require EPA (or local) certification and specialized equipment (recovery machine, vacuum pump, manifold gauges, brazing torch, nitrogen, scale), this is not a simple DIY job unless you are a trained HVAC/R technician. Attempting replacement without proper tools and certification can be unsafe, illegal in some regions, and can damage the system. For safety and regulatory reasons, hire a licensed service technician for compressor replacement.
What should I check before deciding to replace the compressor with W10160407?
Before replacing the compressor, confirm: the start relay/overload and run capacitor are functioning; the evaporator and condenser coils and fan motors are clean and working; ther is no sealed‑system restriction or refrigerant leak (low charge); and the control board/thermostat is not at fault. A proper diagnosis should include electrical tests and a pressure/gas check of the sealed system.If the compressor is electrically shorted, locked, or mechanically failed after these checks, then replacement is justified.
How much does a replacement compressor (part W10160407) typically cost including labor?
Parts and labor costs vary widely by region and model.The OEM compressor part alone can range from a few hundred dollars to more depending on the exact assembly and supplier. With refrigerant recovery, replacement, brazing, evacuation and recharge, and labor, total replacement often ranges from about $400 to $1,200 or more. In many cases,if the refrigerator is older,replacing the entire unit may be more economical. Get multiple quotes and confirm that the quoted price includes recovery, evacuation, correct refrigerant type and amount, and warranty.
Where can I buy a genuine W10160407 compressor and what warranty should I expect?
Buy from authorized whirlpool parts dealers, whirlpool’s official parts website, or reputable appliance parts suppliers to ensure you get a genuine OEM component. Avoid unknown sellers offering parts at drastically reduced prices unless they guarantee OEM authenticity. Warranty terms vary-OEM compressors often carry a limited parts warranty (commonly 1-5 years depending on Whirlpool policy and model). Confirm the exact warranty period and whether labor is covered before purchasing or scheduling the repair.
In Conclusion
The W10160407 Whirlpool refrigerator compressor serves as the central component of the cooling system, converting electrical energy into the mechanical work needed to circulate refrigerant and maintain consistent temperatures. Its reliable operation is critical for food preservation, energy efficiency, and the overall lifespan of the appliance; a malfunctioning compressor can manifest as warm compartments, excessive cycling, or increased energy use, all of which directly affect performance and operating costs.
Given the compressor’s importance and the complexity of refrigeration systems, accurate diagnosis and timely replacement when faults are confirmed are essential. Careful testing helps avoid unnecessary parts changes, while professional replacement using appropriate components and refrigerant-handling procedures ensures safety, restores efficiency, and helps protect warranty coverage and long-term appliance reliability.
