the 38034P â˘Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined âreplacement assembly âconsisting of a twoâspeed alternatingâcurrent drive motor and a âmatched drain pump designed for Speed Queen topâload washers. As a service part, it provides â¤the electrical and mechanical interface that drives tub âagitation and spin at⢠distinct speeds and removes wash water⢠thru the machine’s⤠drain plumbing; â¤the â”2âSpeed 120V” designation identifiesâ the⣠nominal supply⢠voltage and âŁthe motor’s capability to operate at two discreteâ speed/torque settingsâ for wash and spin phases.
In operation âthe motor portion supplies torque and rotational speed toâ the washer transmission or directâdrive â¤coupling⤠to perform agitation âand highâspeed spin,⢠while⤠the pump portion evacuates water from the tub intoâ the drain line. The assembly interfaces with the appliance control system â¤(timing/control board), â¤safety interlocks (lid switch),â the transmission/gearcase â˘or directâdrive couplingand the drain plumbing; electrical âconnections, mounting âgeometry, shaft orientation⣠and rotor â˘inertia are all crucial for correct integration. The twoâspeed function typically provides⢠a lowâspeed,â higherâtorque mode for agitation and a âhighâspeed mode for spin extraction,⢠and the pump must be matched to the washer’s flow â˘and âhead requirements toâ ensure reliable draining.
This article will explain theâ motor and pump functions in more detail, describe electrical and mechanical compatibility considerations (voltage, connector pinout, shaft and mounting dimensions), list⣠common failure symptoms to recognize (no agitation, no spin, humming, failure to drain, overheating), outline diagnostic checkpoints a technician can use (basic â¤electrical and mechanical tests, â¤pump impeller and inlet checks)and discuss practical replacement considerations including matching ratings, mechanical fitand safety precautions. The goal is to provide technicians,⤠engineers, âand appliance owners with the technical data âneeded to assess suitability, diagnose faultsand plan a proper service or⤠replacement without presenting marketing claims.

Function and Role of the 38034P Motor and Pump Assembly in Wash cycle Operation
The 38034P Speed Queen 38034P â¤Washer Motor & Pump Kit 2-Speed 120V is a combined motor and drainâ pump assembly engineered to execute the distinct mechanical duties of agitation, drainingand high-speed spin in compatible washers. The motor is a singleâphase, 120 V twoâspeed unit that achieves different operating RPMs by switching between windings or internal speed-selection circuitry;â lowâspeed is usedâ for agitation and gentle tumbling during wash/rinse⤠cycles, while highâspeed is used for rapid spin to extract water. The â¤pump portionâ couplesâ to â˘the motor or its mountingâ flange and uses âŁan impeller to evacuate water from the tub during drain and spin phases. Control⤠logic from the timer or electronic control board supplies voltage to the appropriate motor winding âŁand to the pump circuitâ soâ that draining coincides with⣠spinand the â˘mechanical interface (shaft, âcouplingand bracket) determines straightforward â¤compatibility with a given Speed Queen chassis and plumbing layout.
Technically, installers and technicians âŁshould verify mechanical fit, shaft orientation, connectorâ pinoutand 120 V supply compatibility before replacement; mismatches in mounting or electrical⣠connectors can produce noise, failure to reach correct speedsor no-drain conditions.Common failure modes observed⤠in this assembly include âa seizedâ pump impeller,⤠worn commutator/brushes or âburned windingsand damaged harness connectors-symptoms includeâ motor humming â˘without shaft rotation, no water extraction despite motor âoperationor intermittent speed changes. Diagnostic steps â¤typically involve checking line voltage to the motor at each commanded state, verifying pump rotation freeâspinand inspecting the coupling for wear.â Theâ following list summarizes core behaviors and checksand the table gives aâ compactâ technical reference for onâsite troubleshooting.
- Two distinct speeds: low for wash/agitation, high for⣠spin/extraction.
- pump âengages during drain⢠and often⣠during spin; impeller blockages are common âservice items.
- Verify 120 V singleâphase supply, correct harness connectorsand proper mounting to ensure compatibility.
- Typical diagnostics: âmeasure voltage⢠at motor terminals, handâspin impeller/shaft, inspect coupling and connectors.

How the 38034P speed â˘Queen â38034P Washer Motor & âPump Kit 2-Speed 120V Works Inside the Appliance
The 38034P Speed Queen⢠38034P Washer Motor & Pump Kit 2-Speed 120V mounts in place of the original drive assembly to supply both â¤the mechanical torque for agitation/spin âand the â˘hydraulic âactionâ for draining. The kit contains⤠a motor âengineered for two discrete âoperating speeds-one low-speed winding for agitation and one high-speed winding for spin-plus a pump⤠assembly that either mounts directly to the motor shaft or couples to it via a short drive⢠coupling dependingâ on the cabinet layout. Electrical control is â˘handled by the washer timer or control board: selecting agitation or spin energizes the appropriate⢠winding â¤or winding tap, while a common⤠neutral and safety ground complete the circuit; thermal âŁoverload protection⢠is typically integrated or provided by an inline fuse/thermostat to protect the motor windings from sustained overcurrent conditions.
Inside the cabinet the motor converts the supplied 120 V AC into rotational motion that is translated to the tub and the pump impeller. The⢠pumpâ evacuates⤠water during drainâ cycles and runs â¤only when the controller supplies âpower â˘to the pump lead or when the motor is in a drain modeâ whereâ a pump coupling is âengaged. Practical âtroubleshooting examples include: â¤a hummingâ motor with no shaft ârotation often indicates a seized pump impeller⢠or worn bearings, whereas motor rotation with no âwater⤠removal indicates âan impeller blockage or âincorrect pump installation.â Verifyâ part⣠compatibility byâ matching shaft orientation,mounting hole pattern,electrical connector pinout,and part number⤠before replacement to ensure correct mechanical⢠fit and correct wiring behaviour.
- Two-speed⣠operation: low for agitation, high⢠for spin.
- Rated for 120 V AC supply with⤠dedicated pump lead.
- Common failure symptoms: humming, â¤no rotationor failure to pump outâ water.
- Compatibility checks: shaft rotation,⣠mounting⢠pattern, connector pinout.

Common Failure Symptoms and Diagnostic Indicators âŁfor the 38034P Motor â˘& Pump Kit
The 38034P Speed⢠Queen 38034P Washer Motor & Pump Kit 2-Speed 120V combines the â¤two components responsible for rotational drive and water removal in many Speed Queen top-load machines:â a two-speed â120 V drive motor (agitate and âspin) and its matched âdrain pump. Inâ normal operation the motor provides a low-speed torque profile for agitation and a high-speed profile for⤠extraction, while the pump runs during theâ drain portion of the âŁcycle to clear tub water. Compatibility with specific models is resolute by the⤠motor mounting, connector harnessand pump âŁinlet/outlet orientation; mismatched kits can fit physically but exhibit harness pin differences⤠or incorrect pulley/coupling arrangements that alter behavior under load. Forâ example, a motor⢠that energizes âand hums but does not⢠achieve spin speed often points to a mechanical â˘coupling or brake/clutch issue â¤rather than the pump, whereas a motor that â¤runs yet â˘the washer⢠does not drain commonly implicates pump blockage or impeller failure within this kit.
technically useful diagnostic indicators include both electrical and mechanical checks: verify presence of control signals and supply, inspect windings and connectors for opens or shortsand assess mechanicalâ resistance on the⣠shaft and pump impeller. A practical troubleshooting sequence is to measure 120 VAC at âŁthe motor connector during â¤the relevantâ cycle, confirm winding continuity⣠and â˘absence of ground faults âwith a multimeterand manually spin theâ pump âimpeller âŁto check for obstruction or seized âŁbearings. Visual â¤evidence such as burned â¤insulation, melted connector housingsor elevated â˘bearing noise helps âŁdistinguish electrical failure from mechanicalâ seizure. The following list summarizes common field symptoms that â˘point toward motor or pump faults, followed by a â¤short reference table âfor⢠quick checks.
- Humming⣠without⣠rotationâ (motor energized but rotor stalled or coupling failed)
- No drain while motor runs (pump impeller clogged,⤠broken,⤠or pump bearings⤠seized)
- Intermittent speeds or failure to shift⤠between agitate/spin (control wiring, speed selectoror winding faults)
- excessive vibration âŁor noise during spin (imbalances, worn bearingsor misaligned coupling)
- Tripped breaker or blown fuses whenâ motor starts (shorted â˘winding or locked rotor increasing current)
| Item | Description |
|---|---|
| Supply | Confirm 120 VAC at motor connector during drive and drain cycles; absence⤠or low voltage indicates control or harness fault. |
| Winding continuity | Continuity⣠across speed â˘windings indicates intact coils; âan open windingâ indicates motor⢠replacement is required. |
| Mechanical load | Manual rotation of âŁthe motor shaft and⣠pump impeller should be smooth; â˘grinding or seizure indicates⤠bearing/pump failure. |
| Visual/thermal signs | Discolored windings, â¤burnt â¤smellsor melted connectors point to overheating or insulation breakdown and warrant replacement. |
Replacement Considerations, Compatibility and Installation Procedure for the 38034P Motor & Pump Kit
Theâ 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined drive motor and drain pump assembly â¤used on specificâ Speed âQueen top-load wash tubs. The âtwo-speed motor provides âŁdistinct low (agitate) and high (spin)â outputs,â while the⤠attached pump⤠evacuates water; speed selection is achieved through the motor’sâ separate windings and the washer’s âŁcontrol wiring rather â˘thanâ an⤠external gearbox.Compatibility depends on matching electrical and mechanical interfaces: âensure the replacement sharesâ the same 120V rating,⤠terminal/harness style, âshaft diameter andâ lengthand bolt pattern so that the drive coupling, âpulley⣠or agitator coupling aligns and the pumpâ inlet/outlet and mounting ears match the washer cabinet geometry. In practice, this means verifying the appliance âmodel number and⣠comparing âphysical dimensions and connector types⤠before ordering or installing the kit.

Q&A
Which Speed Queen washer models âis the 38034P â˘motor⢠& pump kit compatibleâ with?
The 38034P isâ intended for Speed Queen topâload washers⤠that use a 2âspeed,120 V motor and âŁmatching drainâ pump. Compatibility depends âon the washer model and production year, so always âcompare the washer’s model/serial number and the part number on the washer’s⤠parts listâ with the replacement part listing. If in doubt, consult Speed Queen’s parts lookup or the washer’s service manualâ before ordering.
Whatâ symptoms indicate the motor or pump in this kit is badâ and needs âŁreplacement?
Common signs the âŁmotor or pump has failed include: washer won’t⢠agitate or spin (motor fault),washer doesn’t drain (pump⤠fault),loud⣠grinding or whining noises during spin/drain,motor hums but âŁwon’t start,excessive vibration,burning smell or visible smoke,or motor/pump not getting power. Inspect for seizedâ pump impeller, âŁdamaged â¤wiringor⢠burned motor windings to confirm diagnosis.
Can I replace only the motor or âonly theâ pumpor do â¤I have to use the full â38034Pâ kit?
That âdepends on â˘parts availability and what âis actually damaged. Theâ 38034P is offered as aâ combined motor and pump kit for convenience, âbut many suppliers also sell the motor and pump separately. If only⢠the pump is bad, âyou canâ replace just âŁthe pump (and vice versa),â provided you get the correct part numbers and match shaft, â˘mount and electrical⣠connections.
How should âI test theâ motor and pump safely before⢠replacing⤠them?
always â¤disconnect power and water before testing.For theâ motor: visually inspect for⢠burnt windings and loose wires,check motor winding continuity with a multimeter (compare to âvalues in the service manual),and âtest for shorts to chassis (infinite or â˘very âhigh resistance expected).⤠If â˘equipped, test the start capacitor per its rating. For the pump: remove hoses and check for debris or a jammed impeller; with power disconnectedâ you can try to rotate the impeller by hand for⢠free movement. Only qualified technicians should perform live 120 V tests; if you must energize, follow strict⣠safety practices and wiring diagrams.
How do I wire a 2âspeed 120 V motor correctly âwhen installing this kit?
Twoâspeed motors have separate windingâ leads for low andâ high speed plus a common and a ground. âThe âwasher’s controlâ (timer/switch) selects the appropriate âŁspeed lead. Wiring color codes vary,â so follow the wiring diagram on âŁthe washer â¤cabinetâ or motor label:â connect⤠the common to the hot/neutral â¤per⢠diagram, connectâ the appropriate speed lead âto the controland attach the ground. Never â˘guess connections – incorrect âwiring can damage the â˘motor âor control board.
What tools and extra parts should Iâ have on hand âŁbefore replacing the⤠motor and pump?
Typical tools: nut drivers/screwdrivers,pliers,socket set,multimeter,and possiblyâ a belt tension tool ifâ the âdrive uses a belt. Have new hose clamps and replacement hoses/gaskets if they’re worn. â¤If the washer uses a drive couplingâ or belt, inspect and replace â˘the coupling/belt if worn. Keep the â˘service manual or wiring diagram handyâ for reference.â Wear appropriate âPPE and isolate power and water.
After installing the kit the washer hums âbut won’t âspin â- what should I check?
Humming with no spin usually means the motor is âreceivingâ power but not developing torque. Check belt/coupling installation and tension, ensure the motor is mounted⣠securely and the pulley aligns, verify the lid â¤switch and âsafety â¤interlocks, confirm the speed selection and start windings⤠are being energized (wiring),⤠and inspect the transmission/clutch for mechanical failure. A seized⢠pump or obstructed drives can âŁalso cause overload and humming.
Is it safe âor advisable to replace a singleâspeed motor with this 2âspeed 38034P motor?
Not generally recommended. A 2âspeed motor may have â˘different electrical and mechanical â˘characteristics (winding configuration, mounting, shaft size,â control requirements) and may not be â˘compatible âŁwith the washer’sâ timer/control or mechanical âdrive.Only perform an upgrade if the part is explicitly⢠listed as a compatible substitute in the manufacturer’s parts list or service documentation.
