W10160407 Whirlpool Refrigerator Compressor is a sealed motor-compressor assembly used in domestic refrigeration systems; it is indeed teh mechanical device that compresses refrigerant vapor and provides the pressure differential required for refrigeration. As a core component of the sealed refrigerant loop,the compressor combines an electric drive motor and compression mechanism inside a hermetic housing designed to contain refrigerant and lubricant while resisting internal pressures and heat.
Inside the appliance, the compressor pressurizes low‑pressure refrigerant from the evaporator and delivers high‑pressure vapor to the condenser, enabling heat rejection and the cyclical phase changes that produce cooling. It interfaces directly with the evaporator, condenser, refrigerant tubing and metering device (capillary tube or expansion valve), and it also interacts electrically with the refrigerator’s power supply, start device (relay or electronic starter), and thermal overload protector. Its mechanical and electrical condition thus affects system pressures, refrigerant flow, electrical current draw, and ultimately temperature control and defrost behavior.
This article will describe the compressor’s function within the refrigeration cycle, clarify compatibility and identification considerations for technicians and owners, list common failure symptoms and diagnostic checks (electrical continuity, current draw, and pressure readings), and outline practical troubleshooting steps and replacement considerations. Topics will include how to determine whether the compressor or associated components (start relay, overload, or refrigerant circuit) are at fault, safe handling and regulatory notes for refrigerant work, and factors to consider when selecting and installing a replacement unit.

Functional Role of the Compressor in Refrigerator Cooling,System Pressure Regulation,and Defrost Control
The W10160407 Whirlpool Refrigerator Compressor is a hermetically sealed,motor-driven compressor that provides the mechanical compression of refrigerant vapor required to transfer heat from the evaporator to the condenser. By raising refrigerant pressure and temperature on the discharge side, the compressor creates the necessary pressure differential between the suction and discharge ports so the metering device can control flow into the evaporator. In normal cooling operation the compressor modulates runtime based on the control board or thermostat; its electrical and mechanical characteristics directly determine expected suction/discharge pressures, refrigerant charge behavior, and the thermal performance of the sealed refrigeration loop.
Beyond moving refrigerant, the compressor indirectly participates in system pressure regulation and defrost behavior: when the compressor stops for a defrost interval the system pressures equalize and refrigerant can migrate to warm sections, and at restart the compressor must overcome that pressure balance without liquid slugging. When replacing or diagnosing a unit, confirm compatibility of voltage, terminal configuration, mounting, and approved refrigerant, and ensure the start device and overload protection match the compressor’s ratings. Practical diagnostic checks include measuring running and off-cycle pressures, listening for start/hum symptoms, and verifying that excessive vibration or elevated head pressures are not caused by restricted airflow or a failing start relay.
- Common checks: verify model and voltage match, measure suction/discharge with gauges, check start relay/overload, and inspect for refrigerant migration after defrost cycles.

How the W10160407 Whirlpool Refrigerator Compressor Operates Within the Appliance Cooling Circuit and Electrical Control Loop
The W10160407 Whirlpool Refrigerator compressor serves as the heart of the sealed refrigeration circuit by compressing low-pressure vapor from the evaporator into high-pressure vapor that rejects heat at the condenser. As part of the cooling loop it raises refrigerant pressure and temperature to enable condensation, after which the liquid refrigerant is metered back to the evaporator where it absorbs heat. This component must match the appliance’s refrigerant type, mounting configuration and electrical ratings so that system charge, oil compatibility and mechanical fit are correct; because the compressor is a sealed component, swapping in a unit with different specifications can cause lubrication issues, incorrect head pressures, or poor cooling performance despite correct electrical hookups.
Electrically the compressor is controlled by a start mechanism (relay or electronic start device), thermal overload protection, and the appliance control board or thermostat that completes the run circuit; proper operation requires correct line voltage, a functioning start relay, and no internal motor faults. Practical diagnostics for technicians include measuring run and start current, listening for characteristic start/stop sounds, and checking system pressures with gauges-the compressor should draw a steady run current when loaded and produce expected high-side and low-side pressures. Common operational indicators and troubleshooting cues include:
- Start behavior: brief higher current draw as start device engages, then stable run current.
- Pressure response: high-side pressure rises when running; low-side pressure drops near expected evaporator pressure.
- Protection trips: frequent overload or no-start often indicates locked rotor, shorted windings, or repeated control faults.

Common Failure Symptoms and Diagnostic Indicators of a Failing Compressor – noise, no cooling, electrical and thermal faults
The W10160407 Whirlpool Refrigerator Compressor is a sealed motor-compressor assembly whose primary role is to compress refrigerant and maintain the pressure differential required for heat transfer. Failure modes of this compressor typically present as audible mechanical faults (loud knocking, repetitive clicking, or continuous high-frequency vibration), loss of cooling despite apparent motor activity, or electrical/thermal faults where the unit will not start or will run intermittently. In practice, a compressor that hums but will not reach operating speed often points to a failed start device or a seized internal component, whereas a compressor that runs yet the evaporator remains warm suggests refrigerant loss, valve failure, or internal loss of displacement in the compressor itself.
- Abnormal noises: knocking, rattling, or persistent high-pitched whine.
- No cooling: compressor runs or hums but evaporator and cabinet temperatures do not drop.
- Electrical faults: repeated tripping of breakers, high current draw at start, or no continuity through windings.
- Thermal protection activation: compressor cools down, then restarts onyl after a long delay, indicating a thermal cut-out is opening.
Diagnostic indicators technicians rely on include electrical measurements at the compressor terminals (supply voltage, current draw with a clamp meter, and winding continuity or short-to-ground checks), observation of operating temperatures on the compressor shell (warm under load but not excessively hot), and refrigeration-system pressure diagnostics to separate a compressor mechanical fault from a sealed‑system leak or restriction. Check the start relay and any external start/run capacitors for intermittent contact, and verify continuity through the thermal protector-open only when hot and closed when cold-to confirm thermal trips. For example, a compressor that draws significantly higher current then the nameplate rating and produces little pressure differential on the service ports indicates internal mechanical failure or a locked rotor condition, while low/no current with no start and open continuity in the start winding points to electrical winding or start device failure.
| Item | Description |
|---|---|
| Humming without start | Often a failed start relay/capacitor or internal mechanical seizure; verify voltage at terminals and relay operation. |
| No cooling with running motor | May indicate refrigerant loss, valve failure, or reduced compressor displacement; check system pressures and evaporator frost pattern. |
| High current draw | Sign of mechanical binding or degraded windings; compare measured amperage to nameplate and inspect for overheating. |
| Thermal protector trips | Repeated opens suggest overheating from overcurrent or internal friction; test for continuity when cold and absence when hot. |
Compatibility, Replacement Requirements, and Installation Procedures for W10160407 in Supported Whirlpool Refrigerator Models
The W10160407 whirlpool Refrigerator Compressor is a sealed refrigeration pump that converts electrical energy into pressure and flow for the refrigerant circuit; compatibility depends on mechanical mounting, electrical ratings, terminal arrangement, and sealed‑system refrigerant/oil chemistry rather than the nominal part number alone. Technicians should verify that the replacement compressor matches the original’s supply voltage, locked‑rotor amps and terminal configuration, and that its mounting bracket and rubber grommets align with the evaporator and condenser piping layout. The starting device and overload protector must be compatible with the compressor’s start/ run characteristics to avoid nuisance failures or excessive current draw during normal operation.
Replacement requires full refrigerant recovery and sealed‑system service methods: remove the old compressor, replace the filter/drier, perform brazing or fittings replacement with appropriate flux‑free procedures, evacuate to deep vacuum and backfill with the specified refrigerant mass and oil charge. Practical installation checks include confirming vacuum level with a micron gauge (<500 microns target for clean brazed joints), leak testing the joints with dry nitrogen and electronic leak detector, verifying running current with a clamp meter against the compressor nameplate rating, and confirming proper compressor mounting to minimize vibration transfer.
- Essential service steps: refrigerant recovery → replace filter/drier → install compressor → evacuate to deep vacuum → charge with correct refrigerant and oil → run and verify pressures and currents.
| Item | Description |
|---|---|
| Electrical Rating | Match supply voltage and running/locked‑rotor amperage to original specification. |
| Sealed‑System matches | Same refrigerant type and lubricant compatibility; replace filter/drier during service. |
| Installation Checks | Vacuum to ~500 microns, leak test, correct refrigerant charge, and measured operating current. |
Q&A
What is the W10160407 compressor and which Whirlpool refrigerators use it?
W10160407 is a Whirlpool replacement compressor part number used in a range of Whirlpool/Maytag/Roper refrigerators. It is the sealed refrigeration compressor (the motor/pump that circulates refrigerant) sold as an OEM replacement. to confirm compatibility, check the model number sticker on your refrigerator and compare part numbers in the Whirlpool parts database or with an authorized parts supplier – compressors are not universally interchangeable even within the same brand.
What are the common symptoms of a failing W10160407 compressor?
Common signs include: refrigerator not cooling or cooling poorly, compressor not running (no vibration or humming), compressor making unusual loud noises (grinding, clattering), frequent short cycling, or tripping the breaker. Note that similar symptoms can be caused by othre issues (bad start relay, clogged condenser, evaporator fan failure, or refrigerant leak), so a careful diagnosis is needed before replacing the compressor.
Can I test the W10160407 compressor myself with a multimeter?
Yes, basic electrical checks are possible and useful. First, disconnect power. Remove the start relay/overload and measure resistance between the compressor terminals – you should see low resistance (typically single to tens of ohms) between the terminals (indicating continuity of windings) and no continuity (very high/infinite resistance) between any terminal and the metal case (no short to ground).Also check the start device and wiring. These tests identify open windings or shorts but cannot detect internal mechanical problems or loss of refrigerant.
My compressor hums but the fridge doesn’t cool. Is that the W10160407 compressor or something else?
Humming with no cooling can be caused by several things: a failed start device (relay/overload), a mechanically locked or damaged compressor, or an empty/severely undercharged refrigerant circuit. Start by checking the start relay/overload and the evaporator/condenser fans and coils. If the relay is good and the compressor still won’t start (or draws excessive current), the compressor may be mechanically failing. A certified technician should confirm sealed-system refrigerant charge and perform further electrical/mechanical tests.
Is it safe/legal to replace the W10160407 compressor myself?
Replacing a sealed-system compressor involves refrigerant recovery, brazing/soldering sealed refrigerant lines, evacuation, and accurate recharging.In many countries, handling refrigerant and system service must be done by a certified HVAC/R technician and is regulated. For safety (flammable refrigerants in some newer models) and to avoid damaging the system, it’s strongly recommended to hire an authorized service technician to replace the compressor.
What tools and procedures does a technician use to replace the W10160407 compressor?
A qualified technician will recover the refrigerant,remove the old compressor,cut and braze in the replacement,replace the filter-drier,evacuate the system to proper vacuum,leak-test,and recharge to the correct refrigerant type and factory charge.They’ll also check compressor electrical connections, test start components, and measure running current. Proper vacuum, correct refrigerant type/amount, and leak-free brazing are essential for reliable operation.
How much does replacing the W10160407 compressor usually cost and does it make sense vs. replacing the refrigerator?
Costs vary by region but replacement includes parts (compressor, filter-drier, start relay if needed), labor, and refrigerant – the total can be several hundred to over a thousand dollars. For older refrigerators, high repair cost relative to the appliance value may make full replacement more economical. Consider refrigerator age, additional expected failures (other components near end-of-life), and warranty status when deciding.
Can I use a hard-start kit or replace the start relay instead of replacing the W10160407 compressor?
Sometimes a failed start relay or weak starting circuit is the cause of a non-starting compressor. Replacing the start relay or installing a hard-start kit can successfully get a marginal compressor running. However, if the compressor is mechanically damaged or has internal shorted windings, a start device will not fix it. Have a technician measure start/locked-rotor and running current and inspect the compressor before relying on a start kit as a long-term fix.
