The Trane CPT0119 Run Capacitor is a standard single-capacitance component engineered for continuous duty in residential and light commercial HVACR applications. Specifically rated at 5 Microfarads (5 MFD) with a maximum voltage of 440Vac, this oval run capacitor provides the necessary phase shift to optimize motor starting torque and maintain operational efficiency. As a genuine Trane replacement part, it is frequently utilized in blower motors, condenser fan motors, and small compressors where stable power factor correction is critical for preventing winding overheating and premature motor failure. This HVAC capacitor features a non-PCB, oil-filled design housed in a durable aluminum casing. Its compact oval profile allows for installation in tight control cabinets where space is limited. The CPT0119 is rated for 50/60 Hz and can reliably replace units rated at 370Vac, provided the capacitance remains a precise 5 MFD. Utilizing high-grade metalized polypropylene film, this component ensures consistent performance across its service life, maintaining the required rotational electrical field for high-efficiency PSC motor operation. Key Benefits: Precise Motor Support: Delivers a consistent 5 MFD rating to ensure proper amperage across motor windings. Dual Voltage Compatibility: Rated at 440Vac, making it a safe and robust replacement for both 370V and 440V applications. Compact Oval Design: Fits standard mounting brackets and tight enclosures found in Trane and American Standard units. Industrial Build Quality: Features 1/4 inch quick-connect terminals for secure, low-resistance electrical connections. Common Questions: Can I use an oval capacitor to replace a round one? Yes, as long as the 5 MFD and 440Vac (or higher) ratings match and the physical dimensions allow for secure mounting. What are the signs of a failing CPT0119? Common indicators include a humming motor that fails to start, visible swelling of the capacitor casing, or the condenser fan spinning slower than its rated RPM. Is it okay to use a higher voltage capacitor? Absolutely. You can always go up in voltage (e.g., swapping a 370V for a 440V), but you must never install a capacitor with a lower voltage rating than the original. This item is not eligible for free shipping.
