Tecumseh K146-55 Start Capacitor
As a veteran technician, you know that a compressor is only as reliable as its starting components. The Tecumseh K146-55 Start Capacitor is the heavy-duty solution for high-torque startups in demanding refrigeration and air conditioning applications. Rated for 324-389 MFD and 165V, this OEM start capacitor is the direct engineering successor to the legacy 85PS165E16 and 85PS165D16 models. When you're dealing with a compressor that's struggling to roll over or tripping the breaker on LRA (Locked Rotor Amps), this component provides the phase shift necessary to overcome head pressure and ensure a clean start every cycle.
Built for the rigors of the field, the K146-55 features a rugged phenolic case and terminal configuration compatible with standard potential relays. Whether you are performing a compressor repair on a commercial reach-in or a residential heat pump, using this HVAC start capacitor ensures the electrical signature remains within manufacturer tolerances. Its 50/60 Hz frequency compatibility and industrial-grade construction prevent premature failure caused by the high temperatures often found in hermetic enclosures.
Key Technical Benefits:
- Direct OEM Replacement: Replaces 85PS165E16 and 85PS165D64 with exact fitment and terminal alignment.
- High Torque Performance: Delivers 324-389 microfarads to assist compressors in starting under heavy load or non-bleed TXV conditions.
- Industrial Durability: Rated for 165 Vac, engineered for continuous duty cycles in professional refrigeration parts applications.
- Enhanced Motor Protection: Reduces the duration of inrush current, minimizing heat buildup in the start windings to prevent motor burnout.
- Broad Compatibility: Standardized dimensions (approx. 2.6" x 5.3") allow for integration into most Tecumseh condensing unit electrical boxes.
Common Contractor Questions:
Can I use the K146-55 if my old capacitor is rated at 125V?
Yes. In HVACR electrical work, you can always move up in voltage rating, but never down. The 165V rating of this capacitor provides a safer overhead for 115V-120V systems, handling back-EMF more effectively than lower-rated alternatives.
Why is my compressor humming instead of starting even with a new capacitor?
If the start capacitor is within specs, the issue may lie with the potential relay or a seized compressor. Always check the bleed resistor and ensure the relay is dropping the capacitor out of the circuit once the motor reaches 75% speed.
Is this capacitor compatible with both 50Hz and 60Hz systems?
This Tecumseh motor start capacitor is dual-rated for 50/60 Hz, making it a versatile stock item for various international and domestic equipment configurations.
