137108000 Frigidaire Water Drain Pump and Motor Assembly is an electromechanical drain pump unit designed to remove wastewater from laundry and similar household appliances. The assembly typically combines a small AC or DC electric motor with an impeller housing, mounting flange and electrical connector to provide a compact, serviceable pump that can be attached to the appliance chassis and coupled to the drain hose.
Inside the appliance the drain pump evacuates water from the tub or sump during drain and spin cycles and works against the head pressure of the drain plumbing. It is a point of interaction between the hydraulic path (tub, sump, filter, drain hose) and the appliance control system: the pump receives a drive signal from the control board, may be monitored indirectly by water-level sensors or pressure switches, and must be mechanically sealed and mounted to prevent leaks and vibration. Proper electrical supply, sealing, correct hose routing and backflow prevention are all meaningful factors in its reliable operation.
In this article you will learn how the 137108000 frigidaire Water Drain pump and Motor Assembly functions, how to verify compatibility with appliance models and electrical specifications, common failure symptoms to watch for (for example no-drain, continuous hum, leaks or overheating), systematic troubleshooting steps to isolate electrical, mechanical or plumbing causes, and practical considerations when replacing the unit such as verifying mounting orientation, connector type, sealing/gasket condition and OEM part-number matching. The goal is to give technicians, engineers and appliance owners clear technical context for diagnosing and servicing this component safely and effectively.

Function and Role of the Drain Pump and Motor: Hydraulic Flow, Debris Management, and Electrical Interface
The 137108000 Frigidaire Water Drain Pump and Motor Assembly pairs a small electric motor with a molded pump housing and impeller to evacuate condensate and defrost water from the refrigerator’s drip tray to the external drain or evaporator pan.Fluid enters the housing through a screened inlet, is accelerated by the impeller, and is discharged through a short outlet hose; this hydraulic path is intentionally compact to fit under the evaporator compartment while maintaining sufficient head to lift water past plumbing turns. In service this assembly is energized by the appliance control during defrost and heavy-cycling conditions, and it must be matched to the refrigerator model for proper mounting, connector pinout, and flow orientation-verify appliance model numbers and harness compatibility before replacement.
Debris management is achieved with an inlet screen and limited impeller clearance; lint,scale,or broken glass can increase hydraulic drag and motor current,producing audible strain or thermal cutouts. The electrical interface is typically a small multi-pin plug that provides switched supply from the control board and may include a common return or ground; diagnosing failures involves checking for presence of voltage at the connector during the drain event, measuring motor current for abnormal draw, and inspecting the impeller and inlet for obstructions. Common field observations,maintenance actions,and inspection points are summarized below.
- Symptoms of hydraulic or motor issues: slow/no drain, continuous run, noisy bearings, tripped thermal protection.
- Maintenance steps: clear inlet screen, remove visible debris from impeller, confirm proper hose routing and absence of kinks.
- diagnostic checks: voltage at plug during pump operation, motor resistance/continuity, and impeller free-spin test.

How the 137108000 Frigidaire Water Drain Pump and Motor Assembly Works Inside the Appliance: Mechanical Operation and Control Integration
The 137108000 Frigidaire Water Drain Pump and Motor assembly is a compact centrifugal pump and motor module mounted at the base of the appliance that evacuates wash water through the drain hose during drain cycles. Mechanically, the assembly couples a small sealed motor to an axial/centrifugal impeller that pulls water through the tub strainer and pushes it out of the housing; the motor casing and seals protect the windings from splash and detergent exposure, while a molded mounting flange and electrical connector provide repeatable placement and serviceability. The pump typically includes an integrated impeller chamber and outlet port designed to mate with the OEM drain hose and may incorporate a simple check feature or molded path to reduce backflow; when replacing or troubleshooting, match the assembly part number and connector/mount orientation to ensure proper fit and hydraulic alignment with the appliance plumbing.
From a control viewpoint, the motor is switched by the appliance control board (usually via a relay or power switching device) and runs only during designated drain steps or when a diagnostic routine commands it; the board sequences the pump with inlet valves, heaters, and sensors to maintain correct water levels and timing. Common operational behaviors and diagnostic clues include: a humming motor with no flow (blocked impeller or debris in the strainer), continuous running (stuck control output or a failed level/float sensor), or intermittent operation (loose connector or thermal protection cycling). Practical troubleshooting steps for technicians often begin with verifying the control signal and line voltage at the pump connector, inspecting the rotor and strainer for obstructions, and confirming that the drain path and hose are free of kinks or restrictions before replacing the assembly.
- symptoms: no drain, humming, intermittent flow – map to likely causes such as electrical, mechanical blockage, or control logic faults.
- behavior: pump runs only when commanded by the control board and may include thermal overload protection that opens during stall/overcurrent.
- Compatibility: confirm part number,connector type,and mounting orientation to ensure correct replacement and hydraulic alignment.
| Item | Description |
|---|---|
| Mounting interface | Molded flange and screw/tab locations that align with the appliance base and tub outlet. |
| Electrical connection | Two or three-pin plug to the main wiring harness; switched by control board relay/triac. |

Common Failure Symptoms and Visual/Electrical Indicators of Pump or Motor Malfunction
The 137108000 Frigidaire Water Drain Pump and Motor Assembly provides the mechanical and electrical interface that evacuates water from the appliance sump; it is an integrated pump-and-motor unit intended as a direct-fit OEM replacement on compatible Frigidaire machines. In normal operation the motor drives an impeller to generate flow through the discharge port, so failures manifest as hydraulic symptoms (reduced flow, partial drainage, or complete blockage) or electrical symptoms (no run, intermittent run, or abnormal noise). Becuase the pump and motor share the same housing and mounting, a mechanical fault such as a clogged or broken impeller can produce the same customer-visible behavior as an electrical fault, which makes combined visual inspection and electrical testing necessary to determine weather the assembly or an external control/component must be replaced.
- No rotation – motor receives supply but shaft does not turn; check for impeller obstruction, debris in the housing, or a seized bearing.
- Humming or clicking - audible motor noise without full spin can indicate a locked rotor, failed start device, or intermittent supply from a relay or control board.
- Intermittent operation – pump runs sporadically due to wiring harness issues, corroded connectors, or thermal cycling inside the motor windings.
- Reduced flow/slow drainage – partially blocked discharge, worn impeller, or degraded motor torque from winding damage.
- Visible damage or contamination – cracked housing, oil/grease contamination, or water ingress that corrodes electrical connections or bearings.
When diagnosing, perform a visual inspection for physical damage and debris, then verify electrical conditions: confirm correct supply voltage at the pump connector, measure motor winding continuity and insulation to ground, and monitor running current with a clamp meter to detect excessive draw from bearing drag or a shorted winding. practical examples: a motor that hums but draws low current and shows open winding resistance points to an electrical failure; a motor that hums with high current and elevated temperature indicates mechanical seizure or bearing failure. If mechanical clearance cannot be restored or if windings are open or shorted to ground, replacement of the 137108000 assembly is the practical solution as the unit is supplied as an integrated pump-and-motor component.
| Item | Description |
|---|---|
| No rotation | Power present at connector but shaft stationary – inspect impeller, shaft play, and motor winding continuity. |
| Humming / high current | Audible motor noise with elevated current – suggests locked rotor, bearing failure, or shorted winding. |
| Intermittent run | Variable operation often caused by corroded connectors, wiring harness faults, or failing control relays. |
Compatibility and Approved Appliance Models for the 137108000 Frigidaire Water Drain Pump and Motor Assembly
The 137108000 Frigidaire Water Drain pump and Motor Assembly is a combined impeller pump and compact motor designed to evacuate water from the appliance’s sump or wash tub. Its mechanical and electrical interfaces determine whether it will operate correctly in a given appliance: the mounting flange, screw pattern, sump seal diameter, impeller orientation, and the electrical connector pinout must match the original unit.Performance behavior to check includes torque under load (ability to clear obstructions), direction of rotation, and whether the motor’s capacitance/drive characteristics match the washer’s control board; differences in those parameters can cause reduced flow, overheating, or intermittent operation even when the unit physically fits.
- Mounting compatibility: matching bolt pattern and shaft alignment.
- Electrical compatibility: identical connector type and voltage rating or confirmed equivalence.
- Hydraulic compatibility: impeller size, inlet/outlet diameter, and discharge orientation.
- Service compatibility: available cross-reference or OEM approval in parts lists.
Approved appliance models are persistent by manufacturer cross-reference charts and service manuals rather than by visual similarity alone; technicians should confirm the part number against the appliance model/serial number or Frigidaire parts lookup before installation.In practice, replacement is typically accomplished when the physical dimensions and electrical connections match exactly – such as, swapping a failed drain pump that shares the same mounting flange and 3-pin connector without modifying the sump. When in doubt, inspect the original pump label and consult the appliance’s replacement parts list to avoid installing a unit with incompatible motor characteristics or an incorrect seal that could cause leaks or premature failure.

Replacement Considerations and Installation Procedures: Mounting, Seals, Wiring, and Torque Specifications
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is a compact centrifugal pump and plated motor intended to remove process and condensate water from laundry and refrigeration appliances. When replacing this unit, check mechanical compatibility: the pump housing flange, mounting hole pattern, and gasket face must match the appliance sump or drain channel to maintain a reliable seal. Inspect the pump’s elastomer seal and the mating surface for flatness and debris; a distorted mounting surface or torn gasket will allow air ingestion or leaks that change pump behavior (noise, reduced flow, or intermittent operation).Use the OEM part number to confirm fitment and note that small differences in inlet/outlet orientation or mounting boss elevation can require minor repositioning of hoses or brackets during installation.
Electrical and torque details directly affect long-term reliability. Disconnect mains power before accessing wiring and confirm the pump’s rated voltage on the nameplate; many assemblies use a keyed 2- or 3‑pin connector that should be checked for corrosion and correct pinout with a multimeter before re-energizing. Tighten mounting hardware to avoid over‑compressing plastic housings while achieving a secure interface; typical small pump mounting screws are tightened to a low torque to prevent stripping-verify the appliance service manual for the exact value and record it for future service. After installation, secure wiring away from the impeller and moving components, run a short powered test per the service procedure to confirm rotation and noise-free operation, and perform a water leak check under normal drain conditions.
- Verify OEM part number and physical fit before installation.
- inspect and replace gasket/seal if damaged; clean mating surfaces.
- Confirm connector pinout and rated voltage; test continuity and insulation.
- Tighten mounting hardware to specified torque and avoid housing distortion.
- Perform operational and leak tests after installation.
| Item | Description |
|---|---|
| Mounting interface | Match flange and hole pattern; replace gasket if compressed or torn. |
| Torque guidance | Small sheet‑metal or machine screws into plastic housings-use low torque and consult service manual (common range for similar assemblies: 8-12 in‑lb / 0.9-1.4 N·m). |
| Wiring | Keyed 2-3 pin connector; confirm voltage and perform continuity/isolation checks before power-up. |
Troubleshooting and Diagnostics: Multimeter Tests,Bench Testing the Pump/Motor,and Interpreting Fault Codes
The 137108000 Frigidaire Water Drain Pump and Motor Assembly can be diagnosed with basic multimeter checks and a short bench test to distinguish electrical faults from mechanical failures. With the pump disconnected from the appliance, use a multimeter to measure DC or AC continuity and the DC resistance across the motor terminals; a healthy stator will show a stable low-ohm reading rather than an open circuit, and there should be no low-resistance path from any terminal to chassis (indicating a short to ground). Inspect the molded connector and wiring for corrosion or broken pins that can cause intermittent operation. For a bench functional test,securely mount the assembly,apply the rated supply voltage shown on the appliance wiring diagram (often 120 VAC in North American models) using a GFCI-protected source,and verify the impeller turns freely and pumps water; a humming motor with no rotation typically indicates mechanical seizure,blocked discharge,or internal rotor/stator damage rather than a control issue. Confirm physical compatibility (mounting flange, connector pinout, and impeller orientation) before substituting replacement units to ensure the assembly integrates with the control and plumbing of the appliance.
Electronic control fault codes normally map to a small set of conditions-no drain detected, excessive motor current, or motor circuit open/short-and should be interpreted with the appliance service sheet. A persistent drain error while the control supplies correct voltage to the pump suggests a hydraulic blockage,collapsed drain hose,or a mechanically jammed impeller; a code indicating motor fault with out-of-range resistance or leakage points to windings that must be replaced. Use the following checklist to proceed methodically: check wiring and connectors, measure terminal voltage during a drain cycle, verify motor winding resistance and insulation, bench-run the pump under the rated supply while measuring current, and consult the control’s fault-code table to correlate measurements to failure modes. Replace the 137108000 assembly when windings are open/shorted, insulation resistance is low, current draw significantly exceeds the reference range, or the impeller cannot be freed during safe bench testing.
- Check connector continuity and pin condition before electrical testing.
- Measure resistance across motor terminals and to chassis (expect no continuity to ground).
- Measure applied voltage at the connector during a drain command before bench powering.
- Bench test with the correct rated supply and a GFCI; measure current draw and observe impeller behavior.
- Compare findings to the appliance service manual fault-code table and replace if windings are defective or the pump is mechanically seized.
| Item | Description |
|---|---|
| Typical coil resistance | Manufacturer-specific; commonly in the low-ohm range (consult service sheet).Verify for open/short conditions. |
| Expected supply voltage at command | Appliance wiring diagram specifies rated value (frequently enough 120 VAC on North American models); verify before applying bench power. |
| Insulation to chassis | High/OL on multimeter; any measurable low resistance indicates leakage and requires replacement. |
| Current draw while running | Compare to service spec; a substantially higher current indicates mechanical binding or internal motor fault. |
