38034P Speed queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined electric drive motor and drain pump assembly designed for use in compatible Speed Queen washing machines; the designation indicates a two-speed motor intended to operate from a 120-volt supply and an integrated pump to evacuate wash water. The component consolidates the primary mechanical drive function and the hydraulic discharge function into a single serviceable module, supplying rotational torque for agitation and spin cycles while providing the necessary flow to remove water from the tub.
Inside the appliance the motor provides the rotational power that is transferred-either directly or through a transmission/gearcase-to the tub, agitator, or drum, while the pump creates the pressure and flow required to drain water through the machine’s hoses and drain port. The assembly interfaces mechanically with the washer’s mounting points and driveline and interfaces electrically with the control board, cycle timers, lid/latch switches and the house mains. The two-speed capability changes available torque and RPM to suit agitation versus spin phases, and the pump must overcome head height and any inlet or outlet restrictions; thermal protection, electrical connectors and the pump impeller are all part of the module’s functional envelope and can affect system behavior when degraded.
This article will explain the assembly’s functional design and typical installation locations, outline compatibility considerations and OEM identification practices, list common failure symptoms such as lack of spin, failure to drain, excessive noise, overheating or intermittent operation, and provide practical troubleshooting steps including electrical checks, continuity and voltage tests, inspection for mechanical binding or blockages, and bench-testing procedures. it will also cover replacement considerations-matching voltage, speed and mounting interfaces; ensuring correct wiring harness and seals; safety precautions when working with mains voltage; and brief guidance on verifying proper operation after replacement.

Functional role of the Motor and Pump: Torque, Pump Flow, and Electrical Specifications
The motor in the 38034P speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V supplies the mechanical torque required for both agitation and spin phases, while the pump evacuates wash water during drain cycles. This two-speed design delivers a lower-speed, higher-torque mode for agitation and a higher-speed mode optimized for extracting water from the load; selecting the correct speed and ensuring a stable 120V supply are essential for expected performance. Compatibility considerations include matching the motor mounting and shaft orientation, electrical connectors or harness, and any required start/run capacitor or speed-selection linkage – replacing the motor-pump assembly on the same model typically restores original behavior if these mechanical and electrical interfaces are preserved. Such as, a technician replacing a worn unit shoudl confirm the harness pinout and verify the motor’s thermal overload or capacitor requirements before powering the machine to avoid overheating or improper speed selection.
The interaction between motor torque and pump flow determines cycle efficiency: reduced torque under heavy load or low supply voltage increases spin time and can leave more residual moisture, while restricted pump flow (clogged hoses or damaged impeller) increases backpressure and motor current during drain operations.Electric characteristics to monitor include supply voltage, current draw under load, and presence of any run/start capacitors or thermal protectors; a rising current draw under nominal load often indicates mechanical binding, worn bearings, or hydraulic restriction. Practical checks for technicians include measuring voltage at the motor during operation, visually inspecting the pump impeller and discharge path, and listening for abnormal bearings or coupling noise – addressing these points frequently resolves symptoms such as slow agitation, weak spin extraction, or repeated thermal trips.
- Common symptoms to inspect: slow agitation, reduced spin RPM, poor drainage, abnormal noise, and tripping breakers.
- Installation checks: harness pinout match, secure mounting, correct capacitor (if required), and unobstructed pump discharge hose.
- Diagnostic steps: measure line voltage and motor current, inspect pump impeller, and test motor in both speeds with simulated load.

How the 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V Works Inside the Appliance’s Drive and Drain Systems
The 38034P Speed Queen 38034P Washer Motor & Pump kit 2-Speed 120V combines a two-speed drive motor and a matched drain pump into a single replacement unit that mounts to the washer’s drive chassis and plumbing. The motor contains separate speed selections (typically achieved by switching windings or taps) so the drive system can deliver low-speed,higher-torque operation for agitation and a high-speed mode for extraction; the washer’s control circuit or mechanical timer selects the appropriate winding. The pump is mechanically coupled or mounted adjacent to the motor and is energized during drain phases to evacuate the tub through the hose and check valve, which requires correct electrical and mechanical alignment to prevent interference between draining and spinning actions.
Functionally, the assembly must match the appliance’s mounting pattern, shaft orientation, harness connectors, and electrical rating to be an effective replacement; mismatched rotation, connector pinout, or physical mounting will produce poor performance or failure. Common practical checks when servicing include verifying continuity of the motor windings at 120 V, ensuring the pump impeller turns freely and is not clogged, and observing weather the motor changes to high speed only when the machine commands spin. Typical field symptoms that point to this assembly are no drain (pump blockage or failed pump motor), hum without rotation (start circuit or motor winding issue), or failure to reach spin speeds (wiring, control, or incorrect replacement part).

Common Failure Symptoms: Spin Loss, Drain Failure, Excessive Vibration, and Electrical fault Indicators
The 38034P Speed Queen 38034P Washer Motor & pump Kit 2-Speed 120V supplies the two essential rotating assemblies for agitate and drain functions: a two-speed motor that provides distinct low (agitate) and high (spin) speeds, and a pump that evacuates wash water. Spin loss typically appears when the motor fails to develop sufficient high-speed torque – common causes are worn brushes or contacts, open windings in the high-speed winding, or a failed speed-selection mechanism – while drain failure is most frequently enough a mechanical obstruction in the pump, a seized impeller, or loss of power to the pump circuit. Excessive vibration is frequently due to motor or pump shaft end-play, loose mounting hardware, or a failing bearing that transfers oscillation to the tub; electrical fault indicators (burnt insulation, arcing at connectors, circuit breaker trips, or unusually high running current) point to winding shorts, grounding faults, or connector/wiring deterioration.As this is a matched 2-speed 120V kit, confirm replacement parts match the original motor speed, voltage, and connector scheme to avoid incorrect phasing, improper speed selection, or overload conditions during spin cycles.
Troubleshooting should begin with simple mechanical checks and targeted electrical measurements: visually inspect the pump impeller and hoses for debris, verify motor mounts and coupling integrity, and check for axial and radial shaft play.Use a multimeter to confirm continuity of each motor winding and to check for insulation leakage to chassis; use a clamp meter to measure running amps – a motor drawing above its rated current typically indicates binding bearings or a jammed pump, while zero or very low current at applied voltage suggests an open winding or failed speed selector. For a practical test, momentarily apply 120 V to the pump motor input (with the harness disconnected and safety precautions observed) to confirm it spins freely; similarly, measure line voltage at the motor speed-select terminals during a spin cycle to determine whether the control is delivering the expected high-speed feed. The following list and reference table summarize common symptoms and their most likely technical causes for quick diagnostic routing.
- No or weak spin: high-speed winding open, worn brushes, faulty speed selector, or mechanical coupling failure.
- Failure to drain: clogged impeller/hose,seized pump bearing,or loss of pump power due to wiring/connectors.
- Excessive vibration: worn motor/tub bearings, loose mounts, bent motor shaft, or misaligned pump/mounting bracket.
- Electrical fault indicators: burnt smell, arcing, tripped breakers, or high current draw indicating shorted windings or grounding faults.
| Item | Description |
|---|---|
| continuity check | Measure DC resistance of each winding; open/high values indicate broken winding or connector fault. |
| Running current | Clamp-meter measurement; elevated amps suggest bearing/pump seizure or short,near-zero indicates open circuit. |
| Pump bench test | Apply 120 V to pump input off the machine to verify free rotation and rule out plumbing blockages. |
Compatibility and Replacement Considerations: Model Fitment, Mounting, 120V wiring, and Installation Best Practices
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V replaces both the drive motor and its coupled drain pump, so compatibility checks must cover mechanical fit, electrical connections, and pump orientation. Verify the motor shaft diameter and length, mounting hole pattern, and the pump housing orientation against the original assembly; some Speed Queen variants use a different baseplate or an offset pump that requires an adapter bracket. Electrically, this kit is designed for 120 VAC line service and the two-speed motor uses separate windings or tapped leads for low and high speeds; confirm the timer or selector wiring can switch the correct motor leads rather than relying on a separate capacitor or relay scheme. Match the harness plug, spade terminal arrangement, and confirm the chassis ground location before finishing installation to avoid miswiring the speed-select leads or the pump circuit.
Follow disciplined installation and testing procedures: isolate power, document original wire locations or photograph the control harness, and replace worn sealing gaskets and vibration isolators while the unit is open. Align the pump impeller and motor flange so the pump inlet and discharge ports are not strained, tighten mounting fasteners evenly, and route wiring away from moving components and heat sources. Perform a bench or in-situ functional test by energizing the motor at low speed first, then exercise the high-speed winding while monitoring current draw and listening for bearing noise or unusual vibration; excessive current or noise indicates misalignment, binding, or an incorrect wiring configuration that must be corrected before reassembly.
- Confirm bolt pattern and shaft size match the existing assembly
- Match lead colors or wiring diagram for low/high speed and pump power
- Verify pump outlet orientation and hose fitment
- Ensure a secure chassis ground and proper strain relief on all wiring
- Bench-test windings and measure current before final assembly
| Item | Description |
|---|---|
| Voltage | 120 VAC single phase |
| Speeds | Two discrete speed windings or tapped leads (low/high) |
