Tecumseh K146-13 Start Capacitor Kit

For service technicians addressing high head pressures or hard-starting hermetic compressors, the Tecumseh K146-13 Start Capacitor Kit provides the necessary reactive power to overcome initial inertia. This HVAC start capacitor replacement is engineered for a capacitance range of 88-108 MFD and is rated for 330 VAC, making it a standard fit for many high-torque Tecumseh refrigeration compressors such as the AJA series. By optimizing the phase shift in the motor windings, this kit effectively boosts starting torque, ensuring the compressor reaches operational speed rapidly to prevent potential thermal overload trips. A critical component in professional compressor troubleshooting, the K146-13 is designed to withstand the cyclic stress of commercial refrigeration applications, significantly reducing inrush current levels to preserve the integrity of the motor’s internal windings and start relay contacts during the startup phase.

• Enhanced Starting Torque: Provides the significant electrical boost required to start compressors against high differential pressures.
• Inrush Current Mitigation: Protects system electronics and internal motor components by minimizing peak current draw during startup.
• Broad Compatibility: Engineered specifically for Tecumseh refrigeration systems and compatible with several AJA4512YXD and AJA5517EXD compressor models.
• Rugged Construction: Built to industrial standards with a round 88-108 MFD capacitor and 330 VAC rating for reliable duty cycles.

• When should I replace a start capacitor kit instead of just the capacitor? If you observe pitted relay contacts or scorched wiring alongside a failed capacitor, a full kit ensures the entire starting circuit is restored to factory specifications.
• Is the K146-13 compatible with 115V systems? No, this kit is specifically rated for 330 VAC applications, typically found in 208-230V single-phase refrigeration equipment.
• What symptoms indicate a failing capacitor in a Tecumseh compressor? Common field indicators include the compressor "humming" but failing to start, tripped breakers on startup, or the compressor cycling on the thermal overload protector.
