Function and Role of the 38034P Motor andâ Pump Assembly in Speed âQueen Washers
The 38034P Speed Queen 38034P Washer Motor & Pump Kit âŁ2-Speed 120V combines a two-speed drive motor with the⣠drain pump required for normal wash-cycle operation. The motor âhas distinct low and high speed windings and is controlled by the washer’s timer or electronic control to provide agitation âat the lower speed and high-speed spin⢠for⤠extraction.⣠The⢠matched pump assembly evacuates wash and rinse water during drain andâ spin phases; it is indeed either⢠directly coupled or mounted to the âŁsame motor assembly in this kit, so proper alignment of the pump inlet/outlet and shaft coupling is essential forâ reliable operation. Electrical⤠compatibility with âhousehold 120 V supply and correct control wiring are required for the motor to switch cleanly between the two speeds and for the pump to run only during⣠drain intervals.
Technicians should â¤verify mechanical and electrical⣠compatibility before installation: confirm mounting bracket âgeometry, â˘shaft length and direction, wiring harness connectorsand pump port orientation match âthe original unit on the machine. Typical field symptoms â¤that point to motor/pump failure include no agitation or no spin,the motor humming without starting,intermittent drains,or loud grinding/vibration that indicate⤠a seized pump or bearing wear. Simple diagnostic checks include measuring supply voltage âat the motor terminals⣠during the appropriate cycle, inspecting the pump⤠impeller for⢠obstructionsand confirming the control â¤is delivering the correct speed⤠selection. Practical installation tips: ensure the motor is fastened toâ its â˘mounting plate âbefore connecting the pump plumbing, route wiringâ to avoid chafingand test the washer through a full âdrain and⣠spin cycle âafter replacement.
- Common symptoms: no spin, no âŁagitate, pump runs but no water removed, excessive noise during spin.
- Pre-install checks: verify harness pinout, âconfirm 120 V supply,⣠checkâ shaft and pump orientation, inspect pump impeller clearance.
- Installation note: align pump inlet/outlet to existing drain hose routing to prevent stress on fittings.

How the 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V Operates Within the Drive, Agitation and â¤Drain systems
The 38034P Speed âŁQueen 38034P Washer Motor & Pump Kitâ 2-Speed 120V combines a two-speed âAC drive âŁmotor âŁwith a matched drain âpump so the same assembly can handle agitation, highâspeed spinand water evacuation. âIn operation the drive âmotor provides a lowâspeed, highâtorque output for âthe âwash/agitation phase and a highâspeed outputâ for spin extraction; the control timer or electronic board routes 120 V to the appropriate winding âor⣠switch contact to select the required mode.â The pumpâ in the kit is mechanically or portâcoupled to the motor so that when the machine sequences to a drain state⣠the motor âpowers the pump (or a dedicated pump motor within âŁthe assembly) to evacuateâ water before or âduring the spin cycle.
Technically, the assembly interfaces with theâ washer transmission and tub via a âcoupling or shaft that transfers torque to the agitator and⢠basket; during agitation⣠the transmission provides directional reversals or oscillation while the motor runs at the low speed settingand during spin âthe transmission â¤is⢠either locked or allowed to⣠freeâturn so the basket reaches high rpm. Practical implications for technicians: ensure the replacement unit matches connector types, mounting pointsand control wiring for your modeland listen âfor reduced pump flow, loss of⢠torque inâ low⣠speedor inability toâ reach âspin speed as diagnostic⣠cluesâ to motor or pump failure. typical behaviors, compatibility notesand speedy checks are summarized below.
- Low speed: high torque for agitation via transmission coupling.
- High âspeed: spin âextraction of âwater; requires transmission/basket engagement.
- Pump⣠operation: motorâdriven pump evacuatesâ tub during drain cycles; check for clogs or worn impeller.
- Electrical: nominal 120 V AC supply; correct wiring⣠and timer/board control required for speed selection.
- Diagnostics: noise, loss⤠of torque, no drain,⢠or failure to spin âindicate motor, pumpor coupling issues.

Common Electricalâ and Mechanical Failure Symptoms and âDiagnostic Tests
The ⢠38034P Speed⢠Queen 38034P Washer Motor â& Pump Kit 2-Speed 120V combines a twoâspeed⣠drive motor and a matched drain pump into a single replacement assembly used on compatible Speed Queen topâload washers.⢠The motorâ is a singleâphase⢠120 V alternatingâcurrent unit with distinct lowâspeedâ (agitate) and highâspeed (spin) windings or switching paths controlledâ by the washer’s control system; the pump â¤is mechanically coupled and sized âto the⣠washer’s drain plumbing. Technicians should understand that electrical compatibility (correct harness,⢠terminal⣠layoutand control outputs) and mechanical alignment (mounting points, shaft couplingand impeller clearance) are both ârequired âfor proper functionand that visible wear on⢠bearings, sealsor the⣠impeller will change load and current characteristics even if the windings âtest OK electrically.
- Motor does not start or only hums – check incoming 120 VAC âat the âŁmotor connector, verify control board âŁor timer is energizing the appropriate windingand test winding continuity; a humming motor with correct supply frequently enough âŁindicates a failed start/run switching path or mechanical â˘seizure.
- No drain or⤠weak drain – inspect the⣠pump impeller for debris, confirm the pump shaft turns freelyand⢠measure voltage âŁatâ the pump motor while the drain cycle isâ commanded; â˘lack of âvoltage points to control or wiring âfaults,â free shaft but no â¤fluid movement suggests impeller damage.
- Excessive vibration or poor â˘spin speed – compare running current with expected values â˘using â˘a clamp meter while testingâ with a reduced mechanicalâ load; high current with low speed typically indicates bearing failure,obstructions,or aâ slipping/worn coupling.
- Overheating or burning smell – isolate the motor, allow coolâdown, then measure winding resistance for open or shortedâ coils and inspect insulation/commutators; intermittent thermal cutouts or tripped breakers during normal loads indicate internal motor faultsâ or external mechanical âbinding.
Safety first: always disconnect power before performing â˘continuity âŁor resistance checks and⤠use an AC voltmeter and clamp meter for live diagnostics. Practical âŁtroubleshooting sequence: verify correct supply voltage, confirm control outputs duringâ the commanded cycle, perform static⣠windingâ andâ continuity checks,â then⢠run âdynamic tests (voltage under â˘load,⣠current drawand mechanical freeâspin) to separate electrical faults from mechanical failures. For example, a pump thatâ receives 120 â˘VAC during drain but fails to move âwater usually needs mechanical service or replacement, while a motor that receives no voltageâ requires tracing backâ through the control board, interlocksand safety switches.
Compatibility,⤠Replacement Considerations and Installation Best Practices
The 38034P Speed Queen 38034P Washer Motor & Pump âKit 2-Speed 120V combines a two-speed single-phase motor and matched drain pump to provide the agitation and spin/drain functions âfor compatible top-load Speed Queen washers. The motor achieves two distinct mechanical speeds through separate winding tapsâ or an internal âŁspeed-selection mechanism controlled by the washer’s timer or electronic control; the pump is â¤coupled â˘to the motor or motor shaft via a specific âŁmounting and coupling geometry. When assessing compatibility, verify âŁthat the replacement unit matches the original mounting bolt pattern, shaft diameter and length, connector⤠pinoutand⣠nominal supply of 120V, becauseâ mismatches in⤠shaft spec or harness orientation can prevent proper clutch engagement,⤠lead to seal misalignment,â or leave the pump âunpowered even if the motor runs âŁnormally.
Replacement and installation require both âŁelectrical and mechanical checks: confirm continuity⢠and expected resistance of windings, ensure the pump impeller rotates freely and seals are intactand inspect the wiring harness for the correct âsignal/line connections so the washer’s⢠control board will select theâ intended speed and⣠activate the pump. During⢠reassembly, torque âthe mounting fasteners to the original specification to avoid⢠frame distortion, route wiring away from moving parts and heat sourcesand perform a controlled test run to observe current draw,â vibrationand proper drain operation; abnormal current or binding during spin indicates âŁmechanical misalignment âor â˘an internal fault that should be corrected before returning the machine to service.
- Quickâ checks: disconnect power first; match part numbers and âharness; measure â¤shaft and bolt pattern; spin the impeller by âhand; verify winding continuity.

Q&A
Which Speed Queen models is the âŁ38034Pâ Washer Motor & Pump Kit compatibleâ with?
The 38034P is designed forâ many Speed Queen topâload washers thatâ use a 2âspeed 120V motor and a separate drain pump. âCompatibility varies by model⢠and production date, so âŁalways check the washer’s model and serial number against the part listing or the âSpeed Queen partsâ manual. If you can’t find âthe list, open the washer cabinet or check the control panel area toâ locate the machine model tag and compare it with the vendor or⢠manufacturer fitment information.
What does “2âspeed 120V” mean â¤and âŁwhat areâ the two âspeeds used for?
â2âspeed 120Vâ meansâ the motor runs on standard household singleâphaseâ 120 volts and has two distinct operating speeds. The â˘low speed is âused for agitation (washing) and provides the torqueâ and gentle motion⢠required âto clean clothes. The high speed is â¤used âfor spinning to extract water. The washer’s control and clutch/drive system select the appropriate winding/speed⢠during âŁthe cycle.
What symptoms indicate the motor or â˘pump in this kit needs replacement?
Common signs include: the washer won’t agitate or spin (but may hum), the washer won’t drain or drainsâ slowly, loud grinding or rumbling noises from the motor/pump area, burning smell or visible smoke, motor⢠does not start at allor frequent tripping of breakers or thermal overload. If the motor shows burned windings, seized shaftor the pump impeller âis âdamaged âŁor jammed, replacement is usually required.
Can â˘I install the 38034P kit myselfand what basic âŁsteps are involved?
If you have moderate appliance repair⣠experience you can install it yourself.Basic steps: disconnect power and water, drain remaining water from the tub, access and removeâ the cabinet or control (per your model), disconnect â¤wiring and drain hoses, remove the old motor and⣠pump assembly, mount the newâ motor and pump, reconnect hoses and wiring exactly as original (take photos or label wires before removal), reassemble the cabinet, restore power and run a test cycle.If⣠you’re uncomfortable with electrical âwork orâ heavy lifting, hire a qualified appliance technician.
How should I test the âmotor and pump before replacing them?
use a multimeter⤠to check winding continuity and â¤insulation resistance (with power removed). Compare â˘resistance readings â˘to the service manual for your model if available. Inspect the motor shaft for free rotation and the pump impeller for obstructions or damage. With appropriate safety âŁprecautions â¤andâ only if you are qualified,you can verify that the control âsends 120V to the motor terminals during the appropriate cycle step. If windings are open, shortedor the motor is mechanically seized, replacement is indicated.
Does the 38034P kit include â¤all mounting âhardware and seals needed for installation?
Most motor â˘& pump kits include the motor, the drain pumpâ assemblyand common mountingâ hardware (brackets, gasketsand fasteners), but⣠exact contents can vary by supplier. Always check the product âdescription or⤠parts list from the seller to confirm included items.If seals, hosesor additional brackets are not included you may needâ to reuse serviceable â¤originals orâ purchase those parts separately.
After⤠installing the kit, the washer still won’t drain. What should I check?
First verify â˘the pump is receivingâ power when a drain cycleâ is commanded.Check for blockages in the pump inlet, impellerand drain âhose (remove and inspect hoses and âŁthe pump inlet). â˘Ensure the pump impeller is intact and freely rotating. Check⣠the drain line for clogs,air gaps,and⢠correct routing/height. Also confirm the lid switch and control are operating correctly-if the control never signals the pump there will be no drain âeven if âthe⢠pump is good.
what kind âŁof warranty orâ replacement support should I expect for the 38034P kit?
Warranty⢠terms vary by manufacturer and the seller. OEM Speed Queen parts sometimes carry a âŁlimited warrantyâ through Speed Queen, while⢠thirdâparty⤠sellers may offer their own warranty period (commonly 90 days to one âyear). âAlways review⣠the seller’s warranty, return policyand any installation guarantees before purchasing. For best longâterm reliability, use genuine OEM parts when possible and have a qualified technician install â¤the kit if you need warranty coverage for professional âŁinstallation.
