38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined drive motor and drain pump assembly intended for compatible Speed Queen washers. The kit comprises a two-speed electric motor rated for 120 volts and a pump or pump housing that removes water from the tub; together these electromechanical components provide the primary mechanical drive and the fluid removal function required during wash cycles.
Inside the appliance the motor portion supplies rotational torque to the transmission or direct-drive coupling to produce agitation and spin; its two selectable speeds distinguish between low-speed agitation and high-speed spin. The pump portion interfaces with the washer’s plumbing – hoses, trap and drain line – to evacuate wash and rinse water. The assembly is controlled through the washer’s control board or timer and interacts with safety interlocks (such as lid or door switches), water level sensors, and any mechanical clutches or couplers used to change drive modes. electrical characteristics (120 V supply, wiring connectors, grounding) and mechanical factors (shaft orientation, mounting footprint, pump flow capacity) determine compatibility and performance in a given machine.
In this article you will find a technical overview of the kit’s function, key electrical and mechanical specifications to check for compatibility, common failure symptoms (such as no agitation, no spin, failure to drain, humming or intermittent operation), and practical diagnostic checkpoints a technician or informed appliance owner can use. The discussion also covers typical troubleshooting steps to isolate motor versus pump faults and the replacement considerations to observe when installing a like-for-like unit (matching voltage, speed selection, mounting, harness connections and safety precautions) to restore proper washer operation.

Function and Role of the Motor & Pump kit: Drive Mechanics, Drain Operation, and Electrical Interfaces
The 38034P speed Queen 38034P Washer Motor & Pump kit 2-Speed 120V integrates a two-speed single-phase motor with a drain pump to perform both mechanical agitation/spin duties and water evacuation in compatible top-load washers.Mechanically, the motor provides a low-speed, high-torque output for agitation through the transmission or direct-drive coupling and a high-speed output for spin. The pump mounts to the motor or transmission housing and converts motor torque into a fluid flow path that evacuates the tub; depending on the washer design the pump either runs only during the drain interval or is driven continuously while the motor turns during spin.This kit replaces both drive and pump components, so matching the mounting flange, pump orientation, and harness polarity to the appliance model is essential for correct mechanical engagement and drainage performance.
Electrically the assembly accepts standard household line voltage and control signals: it operates from 120V AC single-phase and uses the washer’s timer or control board to select the low- or high-speed winding or to enable a pump-only circuit where applicable. typical interfaces include a multi-pin wiring harness for speed selection and a ground terminal; a thermal overload or internal protection device might potentially be present to prevent overheating. In practical service, technicians verify coil continuity and harness pinouts, confirm correct speed selection under load, and inspect the pump for clogs or impellers seized on the shaft. Common troubleshooting steps and characteristics are listed below to help determine whether the motor, the pump, or the electrical connections are at fault.
- Key features: two discrete speed windings, pump coupling/mount, standard 120V supply, multi-pin connector and ground.
- Symptoms of failure: no spin or no agitation at either speed, failure to drain, abnormal noise from pump or motor, or tripped thermal cutouts.
- practical checks: measure winding resistance, verify voltage at harness during each cycle step, and inspect pump impeller and inlet path for obstructions.

How the 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V Works Inside the Appliance
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V combines a two‑speed, single‑phase 120 V drive motor with a matched drain pump so a single assembly controls agitation, spin and water evacuation. In a typical top‑load Speed Queen washer the timer or control board selects the low‑speed winding for agitation and the high‑speed winding for spin; mechanical coupling or the transmission transfers torque from the motor to the wash basket while the pump is engaged to remove water during drain and spin cycles. The motor assembly usually includes thermal protection and the correct mounting flanges, electrical connectors and pump outlet alignment needed to replace the factory unit without altering the transmission or tub fittings, but installers should verify connector pinout, mounting hole pattern and pump hose orientation for model compatibility before installation.
Understanding how the kit behaves inside the appliance helps isolate failures: the motor provides rotational power and speed selection, and the pump provides the hydraulic flow path to evacuate wash water. Common fault patterns provide diagnostic clues – such as, a humming motor with no rotation suggests seized bearings or internal winding issues, loss of agitation but retained spin points to a failed low‑speed circuit or timer contact, and drain failures often trace to a blocked impeller, a seized pump, or an electrical fault to the pump circuit. Practical checks include verifying supply voltage at the motor terminals, checking continuity of low and high windings, confirming pump impeller free rotation, and inspecting the wiring harness for corrosion or loose connectors before replacing the assembly.
- Low speed: agitation; high speed: spin (selected by timer/control)
- 120 V single‑phase supply with separate speed circuits/windings
- Integrated pump aligned to chassis/hose for drain operations
- Common symptoms: no agitation, no spin, motor hum, or no drain

Common Failure Symptoms and Recommended Diagnostic Tests for Motor and Pump Malfunctions
The 38034P Speed Queen 38034P Washer motor & Pump Kit 2-Speed 120V combines a two‑speed motor and a matched drain pump; the low speed (agitate) and high speed (spin) windings are selected by the machine’s control circuit while the pump evacuates water through a separate drive. Typical failure modes for this assembly include a motor that hums but does not turn, loss of one speed (agitate or spin), pump runs but no drainage, elevated operating temperature, unusual noise from bearings or the impeller, and intermittent operation caused by poor connectors or a failed speed switching device. In practice,a humming motor with no rotation can indicate a seized rotor,failed start circuit,or hydraulic lock in the pump; a pump that turns but does not move water usually points to an obstructed or sheared impeller or a damaged volute.
Diagnosing faults requires a mix of mechanical inspection and electrical testing focused on the two‑speed nature of the unit and the pump coupling. Begin with a visual inspection for debris, damaged connectors, and physical binding; confirm correct supply voltage at the motor harness and then perform winding continuity and insulation checks with a meter. Use a clamp‑on amp meter to compare running current to the nameplate under load,and bench‑apply 120 V to individual speed terminals (with proper safety precautions) to verify both windings independently. Verify the pump by rotating the impeller by hand to confirm free movement and by isolating the pump motor to see if it will pump when powered; if the motor draws high current without turning,bearings or rotor seizure is highly likely,whereas open windings indicate a replaceable motor assembly. The list below summarizes key diagnostic actions and the table provides a quick reference to expected test outcomes.
- Visual check: connectors, harness continuity, debris in pump housing.
- Supply voltage check: verify 120 V at motor supply under load.
- Winding continuity/insulation: ohmmeter for continuity, megohmmeter for leakage to ground.
- Amp draw test: compare running current to nameplate with a clamp meter.
- Mechanical check: rotate shaft/impeller by hand to detect seizure or obstruction.
- Bench test speeds: apply voltage to each speed terminal to confirm independent windings.
| Item | Description |
|---|---|
| Continuity test | Low resistance on each winding indicates intact coils; open circuit indicates winding failure. |
| Insulation test | High resistance to ground (>MΩ) expected; low insulation indicates moisture/shorts and requires replacement. |
| Amp draw | Running current should approximate nameplate under load; significantly higher points to mechanical drag or electrical fault. |
Compatibility, Replacement considerations, and Installation Best Practices for Supported Speed Queen Models
The 38034P Speed Queen 38034P washer Motor & Pump Kit 2-Speed 120V replaces the drive motor and integrated pump assembly on Speed Queen laundry machines that use a two-speed, 120‑volt AC drive. when evaluating compatibility, match the electrical rating, mounting footprint, shaft profile, and harness connector type of the existing assembly to the kit; mismatches in shaft diameter or pump orientation will prevent proper coupling to the transmission or hose routing. Functionally, the two speeds provide an agitate (low) and spin (high) range that are selected by the machine’s control system or mechanical switching; confirm the control board or switch wiring corresponds to the motor’s speed tap identification and that any thermal overload or protector type on the kit matches the original service characteristics.
Follow controlled installation and verification steps to avoid mechanical binding or electrical overloads. Before installation, document and photograph all wiring and harness locations, then secure the cabinet and disconnect power; during mounting, ensure the motor is flat against the frame to prevent misalignment and check that the pump discharge aligns with existing hoses. After mechanical assembly, perform a no-load functional check of both speeds, verify rotation direction and measure line current with a clamp meter-if current exceeds nameplate values or bearings run hot, stop and troubleshoot. Practical checklist for a safe replacement:
- Power off and photograph original wiring; label harnesses before removal.
- Confirm voltage rating and shaft profile against the old motor; ensure pump inlet/outlet orientation allows hose connection without strain.
- Torque mounting fasteners to chassis specifications and secure the motor ground.
- Perform a low-voltage continuity check of windings and a live no-load run test while monitoring current and rotation.
- recheck for leaks, unusual vibration, or noise under a short cycle before returning the machine to full service.

Q&A
What exactly is the 38034P Speed Queen Washer Motor & Pump Kit?
The 38034P is a replacement kit that supplies a two‑speed (agitate and spin) 120V AC drive motor and the associated pump assembly designed for compatible Speed Queen top‑load washers. Kits frequently include the motor, pump, and basic mounting hardware, but contents can vary by supplier – always check the seller’s parts list before purchase.
How do I know if this kit is compatible with my washer model?
Compare the part number on your old motor/pump or the parts diagram in your washer’s service manual to the 38034P listing. Also verify compatibility by entering your washer’s model and serial number on the parts supplier or Speed Queen website. If you’re unsure, take a photo of the original motor/pump and wiring and confirm with the parts dealer or manufacturer.
What are the electrical characteristics and how is the motor wired?
The motor is a two‑speed, single‑phase 120V AC unit. Two speeds are used for agitation and spin. Wiring configurations vary by model: typically you’ll see separate leads for low (agitate), high (spin) and a common, plus a ground. Color codes are not global,so always follow the wiring diagram supplied with the kit or your washer’s schematic and make connections only with the power disconnected.
What symptoms indicate the motor or pump needs replacing?
common signs include: washer won’t spin or agitate but powers on; motor hums or trips a breaker; loud grinding or screeching noises from the motor or pump; washer won’t drain (clog or pump failure); visible leaks from the pump; burning smell or smoke. Confirm diagnosis by checking for voltage at the motor during the cycle and inspecting the pump for blockages before replacing parts.
Can I install the 38034P myself and what tools/steps are involved?
Technically you can install it yourself if you are pleasant with appliance repair.Basic steps: unplug the washer, shut off water, remove access panels or cabinet, document and disconnect wiring and hoses, remove the old motor/pump assembly, mount and secure the new unit, reconnect hoses and wiring exactly as before, reassemble and test.Common tools: screwdriver set, nut drivers, pliers, socket set, multimeter (for checks). If you aren’t comfortable or if the wiring/controls are complex, hire a qualified technician.
Do I need to replace any other parts simultaneously occurring?
It’s an excellent idea to inspect and,if needed,replace related parts while you have access: mounts and gaskets,hose clamps and drain hoses,motor couplers or belts (if applicable),and any worn electrical connectors. Replacing worn ancillary parts reduces the chance of needing another repair soon after the motor/pump replacement.
After installation the washer still won’t run – what should I check?
First confirm the washer has power (breaker/fuse, outlet). Verify wiring connections to the new motor/pump are correct and secure and that any safety switches (lid switch, door interlock) are functioning.Use a multimeter to check that the control is sending voltage to the motor during the appropriate cycle. Check the pump for obstructions and ensure hoses are properly connected. If the motor hums but doesn’t turn, check for seized transmission or mechanical obstruction. if in doubt, consult a service manual or professional technician.
What kind of lifespan and warranty can I expect from this kit?
Lifespan depends on usage, water conditions, and maintenance, but a properly installed OEM replacement motor and pump commonly last several years (often 5-10+ years). Warranty terms vary by manufacturer and retailer – check the product listing and paperwork for the warranty period and any installation requirements (some warranties require professional installation). Keep your receipt and part documentation in case you need a warranty claim.
