137108000 Frigidaire Water Drain Pump and Motor assembly is an electromechanical subsystem used to evacuate standing water from the wash tub or sump of water-handling appliances. The component combines a small electric motor, impeller and pump housing into a single replaceable unit with an electrical connector and mechanical mounting points; its primary purpose is to move wastewater from the appliance enclosure into the household drain line.
Within the appliance, the drain pump and motor assembly is activated by the appliance control board or timer and interfaces mechanically with the tub or sump, the drain hose and any in-line check valve or trap. It thus operates at the junction of the hydraulic and electrical systems: hydraulically it must overcome backpressure in the drain line and resist foreign debris, and electrically it must accept the control signals and line voltage provided by the machine. Proper function depends on intact impeller geometry and seals, correct wiring and mounting, and unobstructed drain routing.
In this article readers will find a technical overview of how the 137108000 drain pump and motor assembly functions, guidance on model compatibility and part identification, common failure symptoms (for example failure to drain, abnormal noise, humming without rotation, and leaks), diagnostic checks a technician can perform (electrical continuity, voltage verification, impeller and inlet inspection) and practical considerations for replacement such as sealing, orientation, wiring connections and post-installation testing. The data is presented to support accurate troubleshooting and informed replacement decisions without replacing appliance-specific service manuals or safety procedures.

Function and Role of the Drain Pump Motor in Frigidaire Refrigeration Systems
The 137108000 frigidaire Water Drain Pump and motor Assembly is an electromechanical sub-assembly that removes condensate and defrost water from the evaporator area and transfers it to the external drain or evaporation tray. The unit consists of a small electric motor coupled to an impeller and is designed for intermittent, short-duration operation controlled by the refrigerator’s defrost cycle or control board outputs. In operation the motor creates a low-flow, relatively high-head discharge sufficient to overcome the appliance’s internal routing and small-diameter discharge tubing; accomplished replacement requires matching the electrical connector, mounting footprint, and intended duty cycle to the refrigerator model to ensure reliable behavior and sealing in a wet environment.
Functionally the motor behaves as a cyclic load device: it receives a commanded voltage from the control electronics during defrost or sensing intervals, runs for a programmed interval to evacuate water, then stops. Common failure modes include impeller blockage, worn bearings causing noise or reduced flow, and open windings or thermal protector trips that prevent startup. Practical diagnostics include visually checking for debris at the inlet, measuring supply voltage at the connector during the expected run interval, and confirming motor winding continuity with a multimeter. When replacing the pump, match the electrical pinout and mounting tabs and confirm the drain path is clear; these steps reduce return visits and ensure the pump operates with the correct wet-duty thermal protection.
- Symptoms: pooling in the drip pan, audible humming without flow, or no run during defrost intervals.
- Quick diagnostics: check for obstruction, verify control voltage at the pump connector, and measure motor continuity.
- Replacement notes: confirm connector type, mounting orientation, and that the pump’s thermal protector and seal design match the appliance.
- Maintenance tip: clean inlet screens and drain tubing to prevent premature impeller binding.

How the 137108000 Frigidaire Water Drain Pump and Motor Assembly Operates Within the Appliance Drain and Defrost Circuits
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is a compact impeller pump and sealed motor that evacuates defrost meltwater from the evaporator drain channel to the refrigerator’s drain pan or external condensate area. it is normally mounted near the evaporator or at the base of the fresh-food compartment and is activated by the appliance control board or defrost relay only during drain/defrost events. proper function depends on an unobstructed inlet and outlet hose, a secure mounting to prevent air leaks, and a correct electrical connection so the pump runs for the intended timed interval rather than continuously.
- Common symptoms indicating pump or circuit issues: standing water inside the fridge, loud or unusual pump noise, pump hum with no flow, or continuous running.
- Quick field checks: verify voltage at the pump connector during a defrost cycle, inspect and clear the drain hose and trap, and listen for motor engagement when the control board commands a drain.
Within the drain and defrost circuits the pump is wired as a switched load: the control board supplies power for a brief, timed cycle after the defrost heater melts frost, or when a water-detection input requests drainage. Compatibility considerations for replacement include matching the electrical connector, mounting footprint, and hose diameter so the original control timing and plumbing are preserved.Typical failure modes are mechanical blockage of the impeller, motor winding failure, or connector/wiring faults; diagnosing these involves both electrical measurement at the harness and a physical inspection of the fluid path before ordering or installing a replacement part.
| Item | Description |
|---|---|
| Function | Removes defrost meltwater from evaporator drain to condenser/drip pan when commanded by the control board |
| Control input | Switched by main control board or defrost relay during drain/defrost cycles |
| Common faults | Clogged hoses/impeller, motor electrical failure, connector/wiring issues |
Common Failure Symptoms and Diagnostic Indicators for Drain Pump and Motor issues
The 137108000 Frigidaire Water Drain Pump and Motor Assembly removes residual water by driving an impeller through a small electric motor; failures therefore manifest as either electrical faults in the motor circuit or mechanical obstruction of the hydrodynamic path. Typical behavior under fault conditions includes no-pump operation with audible humming, intermittent runs, or continuous operation with little or no flow. Compatibility considerations affect diagnostics: replacement assemblies can differ in connector pinout, mounting orientation, and integrated features such as check valves or screens, so visual confirmation of the part number and connector is a necessary first step before electrical testing or mechanical disassembly.
Diagnosing pump and motor issues combines visual inspection, manual mechanical checks, and focused electrical measurements. Start by isolating power and verifying that the impeller can rotate freely by hand and that the pump housing and hoses are clear of debris; if the motor hums but the impeller does not turn, suspect a seized bearing, broken rotor coupling, or internal obstruction. For electrical faults, measure presence of supply voltage at the pump connector, then check motor winding continuity and insulation to ground; intermittent voltage or a control-board pulse without corresponding motor action narrows the fault to the motor/impeller sub-assembly or its connections rather than the main control. Practical examples: a unit that trips a GFCI or breaker suggests short/ground fault or stalled rotor, while persistent wetware after a completed cycle with the motor running indicates blocked discharge or a worn impeller that cannot generate head.
- Humming/no spin: motor energized but impeller immobilized (mechanical seizure or internal debris).
- Intermittent operation: loose connector, broken wire, or intermittent control signal.
- No power at connector: blown fuse, open thermal protector, or failed control board output.
- Noise/vibration during run: damaged bearings or imbalanced impeller.
- Leakage or reduced flow: seal failure, worn impeller, or clogged outlet.
| Item | Description |
|---|---|
| Electrical test | Measure supply voltage at the pump connector, verify motor winding continuity and check for shorts to chassis ground. |
| Mechanical test | Confirm free rotation of the impeller, inspect inlet/outlet hoses and screens for clogging, and listen for bearing noise under hand spin. |
| Control verification | Observe control-board output during a drain cycle (voltage or switched hot); absence of command indicates upstream control fault. |
| Compatibility check | Match mounting, connector pinout, and rotation direction before replacement; some assemblies include integrated check valves or filters that affect installation. |
Compatibility Matrix, Replacement Considerations, and Installation Best Practices
The 137108000 Frigidaire Water Drain Pump and Motor Assembly serves as the electromechanical device that evacuates wash and rinse water from the washer tub. When evaluating compatibility, match the pump’s mechanical footprint, outlet orientation, and harness connector to the appliance chassis; differences in housing shape or outlet position can prevent proper hose routing even if the motor and impeller appear similar. Confirm the part number stamped on the pump and compare control-wire assignments on the appliance wiring diagram: the motor is driven by the washer control board, so identical electrical interfaces (connector type and signal wiring) are required to avoid rewiring. Inspect the pump body and impeller for wear or deformation before installation and consider replacing old hose clamps and gaskets to ensure a leak-free seal during service replacement.
- Verify model number and match mounting tabs and outlet orientation before ordering.
- Check connector pinout against the washer wiring diagram; adapt only with proper insulated splices or approved harness adapters.
- Replace hose clamps and gaskets during pump replacement to prevent leaks.
- Test for motor continuity and free-turning impeller prior to installation.
| Item | Description |
|---|---|
| Electrical interface | Match connector style and control-wire assignments on the appliance wiring schematic. |
| Mechanical mount | Mounting tab locations and outlet orientation determine fit and hose routing. |
| Connector | Commonly a multi-pin plastic plug; use OEM harness or equivalent crimp/heat-shrink repairs. |
| Common failure modes | Impeller blockage, worn seals, motor bearing failure, and connector corrosion. |
During installation, position the pump to avoid kinks and maintain a downward slope in the drain hose where possible to reduce siphoning and residual water pockets. Secure the pump to the frame with the original fasteners to control vibration; excessive torque on the plastic housing can crack mounting bosses, while too-loose mounting allows movement that shortens service life. Electrically, isolate power before connecting, verify proper grounding, and perform a short run-cycle after installation to confirm flow and listen for abnormal noise that indicates impeller rubbing or an obstructed inlet. If the pump hums without moving water, check for debris at the inlet, verify impeller freedom, and confirm that the control board is supplying the expected drive signal rather than assuming a pump failure without diagnostic checks.
Q&A
What appliances use the 137108000 Frigidaire Water Drain Pump and Motor Assembly?
The 137108000 drain pump and motor assembly is an OEM replacement part used on a range of Frigidaire washing machines (and some Electrolux/White-Westinghouse models that share Frigidaire components). Because exact fit varies by model, always confirm compatibility by matching the part number to your washer’s model number or checking the manufacturer’s parts list before purchasing.
What are common signs the 137108000 drain pump is failing?
Typical symptoms include the washer not draining, water remaining in the tub after a cycle, unusually loud grinding or humming noises during drain, leaks under the machine, and error codes related to drainage. A humming noise with no water movement frequently enough indicates the motor is trying to run but the impeller is jammed or the bearings/motor have failed.
How can I test the pump to confirm it needs replacement?
First disconnect power. Visually inspect for debris or clogs in the pump housing and hoses. Use a multimeter to check continuity across the pump motor terminals (you shoudl read a low resistance; an open circuit indicates a bad motor). Also try spinning the impeller by hand-if it’s seized or has excessive play, replacement is needed. If the motor hums but won’t spin, the pump is typically faulty.
What tools and safety precautions are needed to replace this pump?
Basic tools: Phillips and flathead screwdrivers, needle-nose pliers, a 1/4″ nut driver or socket set for panel screws, towels and a shallow pan for water, and a multimeter for verification. Safety: unplug the appliance (or turn off power at the breaker) before starting,shut off the water supply if applicable,and wear gloves to protect from sharp sheet metal. Work on a dry surface and keep small parts organized.
What are the high-level steps to replace the 137108000 drain pump?
Steps (general): 1) Unplug the washer and move it to access the back or front service panel. 2) Drain residual water into a pan by opening the drain hose or filter. 3) Remove the service panel to access the pump. 4) Disconnect electrical connectors and hose clamps, note hose routing. 5) Remove mounting screws/clips and take out the old pump. 6) Install the new pump, reattach hoses and connectors, secure the pump and replace the panel. 7) Reconnect power, run a drain/spin cycle and check for leaks. Always follow the appliance’s service manual for model-specific instructions.
What electrical characteristics should I expect from this pump?
On North American models the pump motor is typically designed for standard household mains voltage (about 120 VAC) and draws moderate current during operation. Exact voltage, current, and wiring details are printed on the pump label-verify those values on the part you have and always disconnect power before testing or replacing the pump.
Can I repair the 137108000 pump instead of replacing it?
Minor issues such as debris removal, unclogging the impeller chamber, or replacing a hose clamp can sometimes restore function. Though, motor failures, worn bearings, or damaged impellers generally require full pump assembly replacement. As the pump assembly is sold as a sealed unit and replacement parts for the internal motor are rarely available, replacement is usually the recommended and most reliable fix.
How can I extend the life of the drain pump and avoid future problems?
Preventive measures: regularly clean the washer’s lint trap/filter and drain hoses, avoid overloading the machine, remove coins, pins and other foreign objects from pockets before washing, and periodically inspect hoses and clamps for wear. Promptly address unusual noises or slow draining to prevent secondary damage to the pump motor.
