TECUMSEH KA55HXKGE-8331 – Condenser Fan Motor | Tecumseh Compressor Platform
Engineering Background
Tecumseh Products Company is a globally recognized manufacturer of hermetic compressors and associated HVAC/R drive components. The KA55HXKGE-8331 is a purpose-engineered condenser fan motor designed to operate in tandem with Tecumseh compressor assemblies across light commercial and residential refrigeration systems. Its design prioritizes thermal resilience, low-vibration airflow delivery, and long-cycle reliability under continuous-duty condensing conditions.
Product Positioning
The KA55HXKGE-8331 is specified by HVAC/R system integrators and OEM equipment builders who require a drop-in fan motor solution with verified dimensional and electrical compatibility with Tecumseh condensing unit platforms. It is the preferred choice where motor replacement must maintain original airflow performance without re-engineering the fan deck or blade assembly.

Proven Application Environments
- Light Commercial Refrigeration — Reach-in coolers, display cases, and walk-in condenser units using Tecumseh compressor assemblies
- Residential Split-System Air Conditioning — Outdoor condensing unit fan deck replacement on Tecumseh-driven systems
- Cold Chain & Food Service Equipment — Blast chillers, prep-table condensers, and undercounter refrigeration
- Industrial Process Cooling — Fluid coolers and process chillers with Tecumseh compressor cores
- OEM Equipment Manufacturing — Factory-line integration into new condensing unit assemblies requiring OEM-matched fan motors
- Field Service & MRO Replacement — Direct swap for failed or degraded condenser fan motors without fan blade or shroud modification
Engineering Advantages
- OEM Platform Match — Engineered to Tecumseh’s dimensional and electrical envelope; eliminates adaptation hardware and re-commissioning risk
- TEAO Enclosure — Totally Enclosed Air Over design resists moisture ingress, dust, and refrigerant vapor contamination in outdoor and semi-outdoor installations
- Automatic Thermal Reset — Built-in protector prevents winding burnout during locked-rotor or high-ambient events; self-resets on cool-down without manual intervention
- Low Vibration Profile — Precision-balanced rotor reduces bearing fatigue and fan blade stress, extending system MTBF
- Field-Reversible Rotation — Lead-swap reversibility allows a single SKU to serve both CW and CCW fan deck configurations, reducing spare-parts inventory
- Continuous-Duty Rating — Designed for 24/7 condensing duty cycles typical of commercial refrigeration and process cooling
System Architecture & Signal Flow
In a standard Tecumseh condensing unit, the KA55HXKGE-8331 fan motor is wired in parallel with the compressor contactor output. On thermostat call for cooling, the contactor energizes both the compressor and the condenser fan simultaneously. The PSC motor draws run current through its main winding while the run capacitor maintains phase shift across the auxiliary winding, producing continuous torque at rated RPM. The fan blade mounted on the motor shaft draws ambient air across the condenser coil, rejecting heat absorbed by the refrigerant. The built-in thermal protector monitors winding temperature and opens the circuit if the motor exceeds its thermal limit, protecting both the motor and the compressor from high-head-pressure events caused by loss of condenser airflow.

Technical FAQ
Q: Is the KA55HXKGE-8331 a direct OEM replacement or an aftermarket equivalent?
A: It is sourced as an OEM-specification part from Tecumseh-authorized supply channels. Konmask does not supply aftermarket substitutes for this SKU.
Q: What run capacitor value is required for this motor?
A: Capacitor µF rating is confirmed from the motor nameplate at order stage. Contact Konmask for the datasheet before ordering a replacement capacitor separately.
Q: Can this motor be used with a variable-frequency drive (VFD)?
A: PSC motors are not designed for VFD operation. This motor is intended for across-the-line single-phase supply. Consult Konmask if variable-speed condenser fan control is required.
Q: What is the lead time for this part?
A: Standard lead time is 3–7 business days for in-stock units. Express options are available. Contact Konmask for real-time stock status.
Q: Does Konmask provide a warranty on this motor?
A: Yes. Konmask provides a 12-month warranty against manufacturing defects under normal operating conditions. Warranty claims are processed via [email protected].
Q: Can I return the motor if it is not compatible with my unit?
A: Konmask recommends confirming compatibility before purchase. Returns are accepted within 30 days for uninstalled units in original packaging. Contact support for RMA authorization.
