W10160407 Whirlpool Refrigerator Compressor is a sealed refrigeration compressor assembly used in Whirlpool household refrigerators and freezer units. As a primary mechanical component of the sealed refrigeration circuit, the compressor contains the motor and compression mechanism in a hermetically sealed shell and is specified to move refrigerant vapor through the system at the pressures and flow rates required by the appliance design.
Inside the appliance the compressor’s role is to draw low‑pressure refrigerant vapor from the evaporator, compress it to a higher pressure and temperature, and discharge it to the condenser where heat rejection occurs. It therefore directly interacts with the evaporator, condenser, expansion device (capillary tube or thermal expansion valve), refrigerant lines, and any receiver, drier or accumulator present in the system. Electrically it interfaces with the refrigerator’s supply, start/run components such as relays and overload protectors, and the control board or thermostat that manages cycling; mechanically it is indeed mounted with vibration isolation and connected to the sealed refrigerant circuit via service ports or tubing joints.
In this article readers will find technical coverage of the compressor’s function within the refrigeration cycle, guidance on how to confirm compatibility with specific refrigerator models, common failure symptoms (such as loss of cooling, excessive noise, failure to start, or frequent cycling), and diagnostic considerations a technician might use to isolate compressor‑related faults versus ancillary system problems. The article will also outline practical replacement considerations – including matching electrical ratings and displacement, refrigerant and oil compatibility, mounting and service connections, and the need for proper refrigerant recovery and evacuation – so appliance owners and service technicians can plan repairs or commissioning in a safe, standards‑compliant manner.

Function and Role of the Compressor within the Refrigerator’s Refrigeration cycle
The W10160407 Whirlpool Refrigerator compressor serves as the pump that maintains refrigerant circulation and the necessary pressure differential between the evaporator (low side) and condenser (high side). Mechanically it converts electrical energy into mechanical compression-most commonly via a hermetically sealed motor and a piston/rotary/scroll compression element-raising refrigerant vapor pressure and temperature so heat can be rejected at the condenser. The compressor’s displacement, oil charge, electrical ratings, and terminal/mounting configuration determine whether it is compatible with a given refrigerator refrigeration circuit; replacing the unit requires matching those parameters and the system refrigerant to preserve lubrication, valve timing, and volumetric capacity of the original design.
Functionally the compressor governs delivered cooling capacity, cycling behaviour, and the steady-state evaporator superheat and condenser subcooling. Symptoms such as diminished suction pressure, elevated amp draw, inability to reach set temperatures, or abnormal noise often indicate internal leakage, valve failure, or motor stress rather than a refrigerant-onyl issue; conversely, a compressor that runs but cannot build discharge pressure suggests loss of compression or internal valve damage. Technicians confirm compressor condition with targeted checks-line-current measurement, insulation and continuity testing, and suction/discharge pressure readings with a manifold gauge-followed by correct recovery, evacuation, and oil/refrigerant charging procedures if replacement of the W10160407 or another compressor is required.
- Create and maintain the pressure differential required for refrigerant phase change and heat transfer

How the W10160407 Whirlpool Refrigerator Compressor Operates Internally and Interfaces with System Controls
The W10160407 Whirlpool Refrigerator compressor is a hermetically sealed electric motor-compressor assembly that converts low-pressure refrigerant vapor from the evaporator into high-pressure vapor for condensation. Internally it contains a motor (typically single-phase) coupled to a compressing mechanism (reciprocating,rotary,or scroll depending on model),and an oil charge that lubricates bearings and valves. The compressor relies on start and run components-either internal/embedded devices or external relays/overloads-to manage high inrush currents during spin-up and to protect the motor from overheating. In service, the compressor’s mechanical performance (displacement, oil condition, valve integrity) determines refrigeration capacity and is the primary compatibility concern when replacing the unit: mounting footprint, terminal layout, and rated electrical input must match the refrigerator’s control and power systems for proper operation.
System controls interface with the compressor by switching line voltage and by monitoring electrical and thermal behavior: the thermostat or control board closes the circuit to apply mains voltage to the compressor terminals, a start device (relay or PTC) briefly engages to provide additional starting torque, and a thermal overload or current-sensing element disconnects the motor on excessive load or stall.Control logic can also use compressor current and suction/discharge temperature readings to detect refrigerant charge issues, valve failure, or mechanical wear; such as, prolonged high current with low temperature rise suggests a locked rotor or restriction. Common practical diagnostic checks for technicians include verifying voltage at the compressor’s terminals, measuring running current, and listening for characteristic start/stop patterns to determine whether the fault is electrical (control or start device) or mechanical (internal failure or system restriction).

Common Failure symptoms and Diagnostic Indicators of Compressor Malfunction
The W10160407 Whirlpool Refrigerator Compressor is a hermetic refrigeration compressor designed to provide the pressure differential required for refrigeration cycles in compatible Whirlpool units. In normal operation the compressor should draw a steady run current close to the nameplate rating, start reliably with a single engagement of the start relay or capacitor, and maintain a cyclical duty that reflects load and thermostat control. Mechanical or electrical faults change that behavior: seized or damaged valving will raise current draw and reduce suction pressure, degraded windings or internal shorts will show as abnormal resistance readings or earth leakage, and a failing start device will produce repeat click-and-stop starts even though the compressor motor itself may be sound. Compatibility with the appliance depends on mounting,electrical specifications,and refrigerant type,so technicians should confirm these before replacing a unit.
- Warm refrigerator/freezer while compressor runs or hums continuously
- Compressor not starting but clicking (repeated relay trips)
- High measured running current compared with nameplate rating
- Short cycling (frequent on/off) of the compressor motor
- Burnt smell, oil leak, or compressor case abnormally hot to the touch
Diagnostic workflow focuses on electrical and mechanical indicators: measure run and start winding continuity with a multimeter, perform a clamp-ammeter measurement of operating current and compare to the nameplate, and verify the start relay/capacitor operation. A typical practical check is to isolate the compressor from the circuit, measure winding resistance (continuity between terminals but no continuity to case), then apply power through a known-good start device to observe whether the compressor transitions to steady run. Also correlate compressor behavior with system pressures and evaporator/fan operation-if pressures suggest low refrigerant or an obstructed capillary, the compressor will run hot and pull higher current even if the windings are electrically sound.use the table below as a swift reference for common electrical and observable indicators that guide replacement versus servicing decisions.
| Item | Description |
|---|---|
| Run current | Measure with clamp-ammeter and compare to compressor nameplate; sustained current above nameplate indicates mechanical loading or electrical fault. |
| Winding continuity | Continuity between terminals expected; open winding indicates failure. No continuity to case (ground) – presence indicates internal short to ground. |
| Start device | Intermittent clicking with no spin often points to a faulty start relay or capacitor rather than the compressor motor itself; substitute known-good start device to isolate. |
| Thermal/visual cues | Overheating, oil stains, or burnt odor indicate internal damage or loss of lubrication and generally warrant replacement. |
Compatibility, Replacement Considerations, Installation Requirements and Troubleshooting Procedures
The W10160407 Whirlpool Refrigerator Compressor is a hermetically sealed compressor designed to compress refrigerant vapor and maintain the pressure differential required for heat exchange in the refrigeration circuit. Compatibility and replacement decisions require matching the compressor’s electrical ratings (voltage and locked-rotor/start current), displacement/capacity, terminal and mounting configuration, and the refrigerant/oil type originally used in the system. Substituting a physically similar unit with different displacement or oil characteristics can change evaporator and condenser pressures,reduce cooling capacity,or cause premature motor overload; likewise,using a compressor intended for a different refrigerant (such as,one designed for R134a versus R600a) requires changes to the sealed system and is not a drop-in swap without appropriate system modifications and safety considerations.
installation requires standard sealed-system service procedures: controlled recovery of existing refrigerant, removal with care to avoid contaminating the oil, replacement of the filter-drier, proper brazing or refrigerant-line connection, deep evacuation to remove moisture and non-condensables, and charging to the manufacturer’s specification. Typical troubleshooting steps include verifying line voltages and amp draw against the compressor nameplate, checking start components (relay/overload or start capacitor) and motor winding continuity, and measuring static and running pressures to distinguish electrical, mechanical, or refrigerant-related faults. Practical technician checks often proceed in this order:
- Symptom: humming but not starting – check start relay/capacitor and supply voltage; measure locked-rotor current.
- Symptom: runs hot or high amp draw – verify airflow across condenser, check evaporator load and refrigerant charge.
- Symptom: rapid cycling or poor cooling – inspect for restricted metering device, low charge, or faulty thermostat/controls.
- Symptom: oil or refrigerant leaks – perform dye or leak-detection testing and replace filter-drier and any compromised tubing before recharging.
| Item | Description |
|---|---|
| Electrical | Match nameplate voltage and rated start/locked-rotor currents; verify branch-circuit protection. |
| Refrigerant/Oil | use the refrigerant specified for the refrigerator model; maintain correct oil type/level when replacing compressor. |
| Mounting & Connections | Ensure the mounting feet, vibration isolators, and terminal orientation match the cabinet and wiring harness. |
| Service Procedures | Recover refrigerant, replace drier, evacuate to manufacturer vacuum spec, charge to specified weight or pressure. |
Q&A
What is the W10160407 compressor and which refrigerators is it compatible with?
The W10160407 is a sealed refrigeration compressor assembly used on a range of Whirlpool-family refrigerators (Whirlpool, KitchenAid, Maytag, Amana and some Kenmore models). It is indeed an OEM-style replacement part but compatibility depends on the refrigerator model number and the compressor mounting/line set and refrigerant used.Always verify fit by checking the refrigerator’s model number and the part cross‑reference on the manufacturer or authorized parts supplier site before buying.
What are the common signs the W10160407 compressor is failing?
Common symptoms include: the refrigerator stops cooling or has reduced cooling, compressor hums or clicks but will not start, compressor runs briefly then trips off, unusually high current draw on the compressor circuit, freezing in the evaporator or warm condenser, and visible oil or refrigerant leaks. Noise (loud rattling or knocking) can also indicate internal mechanical failure. These symptoms can also be caused by start devices, capacitors, or control and thermostat failures, so proper diagnosis is required.
How can I test the W10160407 compressor to confirm it’s bad?
Perform these checks (power removed and panels safely opened unless specified otherwise): 1) Visually inspect for oil/refrigerant leak and burn marks. 2) Use a multimeter to measure resistance between the three compressor terminals (S, C, R) – you should see finite low ohms between combinations and the values should form a logical ratio (no open circuits). 3) Check for continuity between compressor shell and terminals – there should be no continuity (no short to ground). 4) With the refrigerator running, measure running current with a clamp ammeter and compare to the nameplate rated running/current specs. 5) Test or temporarily swap the start relay/capacitor or use a known good hard‑start kit; many “won’t start” compressors are actually start-device failures. If windings are open or grounded, or the compressor draws locked-rotor current and won’t start after verifying start device, the compressor is likely bad. For refrigerant pressure and leak diagnostics, use proper gauges - those steps require certified handling.
Can I replace the W10160407 compressor myself?
Replacing a sealed refrigerator compressor is advanced work. It requires refrigerant recovery (legal requirement in many jurisdictions and requires EPA certification in the U.S.),cutting and brazing copper tubing,installing a new filter/drier,evacuating the system with a vacuum pump,and recharging with the correct refrigerant charge. if you are not certified and experienced with refrigeration service, you should hire a qualified appliance/refrigeration technician. Attempting to do it without proper tools and certification can be illegal, unsafe, and can damage the appliance.
What other parts or services should be done when replacing the compressor?
Best practice is to replace the filter/drier (or suction accumulator), replace the start relay/overload or install a hard‑start kit if recommended, and use new gaskets/fasteners as needed. The system must be brazed correctly (often with nitrogen purge to prevent oxidation), evacuated to a deep vacuum, leak‑tested, and recharged with the exact refrigerant type and charge specified on the nameplate.Some technicians also replace suction/discharge service valves if corroded. Failure to replace the filter/drier or properly evacuate the system can damage the new compressor quickly.
How much does a W10160407 compressor replacement typically cost and is it worth repairing?
Part cost for the compressor alone is variable (commonly a few hundred dollars for OEM units),while full service replacement (compressor + parts + labor + refrigerant recovery/recharge) often ranges from several hundred to over a thousand dollars depending on region and refrigerant type. Whether it’s worth repairing depends on the fridge age, cost of parts/labor, and whether other major components (evaporator, sealed system, control boards) are likely to fail soon. For older units near end of life, replacement of the refrigerator is sometimes more economical.
How do I safely isolate and access the W10160407 compressor for diagnosis?
Safety steps: unplug the refrigerator and shut off power first. Locate the compressor (usually at the rear, bottom). Remove the rear access panel to expose the compressor and start device. Avoid touching live terminals unless power is intentionally applied for testing. When performing electrical tests, use insulated tools and follow lockout/tagout procedures. Do not attempt to open the sealed refrigeration circuit or puncture lines; refrigerant handling must be performed by a certified technician. If you need to measure running current or use a snubber/test setup, restore power only after panels are repositioned to avoid accidental contact.
Are there aftermarket alternatives or cross‑reference numbers for W10160407 and what about warranty?
Aftermarket compressors and remanufactured units exist, and some suppliers provide cross‑reference numbers; though, compatibility, mounting, and refrigerant type must match exactly. OEM compressors and parts often come with limited warranties through authorized parts dealers; remanufactured compressors may have different warranty terms. Always buy from reputable suppliers and confirm warranty coverage and return policies. Keep the refrigerator model number and compressor nameplate facts when ordering to ensure correct match.
