The Trane CPT0076 Run Capacitor is a high-performance OEM component engineered for single-phase motor applications in HVACR equipment. Featuring a capacitance of 4 Microfarad (MFD) and a voltage rating of 370Vac, this oval run capacitor is designed to provide the necessary phase shift for motor starting and continuous operation. Constructed with high-grade metallized polypropylene film and housed in a rugged aluminum casing, the Trane 4 MFD 370V capacitor ensures stable electrical properties even under high-duty cycles. As a specialized HVAC motor run capacitor, it is compliant with EIA-456 standards, offering a high reliability rating for residential and light commercial condenser fan motors and small blowers. The Trane CPT0076 features standard 1/4 inch quick-connect terminals for rapid field replacement and is a direct substitute for legacy Genteq and GE industrial models. For technicians servicing Trane or American Standard units, using this OEM replacement capacitor ensures the motor stays within its specified torque range and prevents premature winding failure due to capacitance drift. Key Benefits for Technicians: OEM Precision: Genuine Trane replacement ensures exact fit and electrical matching for compatible air handlers and condensers. Stable Capacitance: Low-loss metallized polypropylene film maintains a ±10% tolerance across a wide operating temperature range. Compact Oval Geometry: The oval footprint allows for easy mounting in tight electrical control boxes where space is limited. Standardized Terminals: Equipped with quad-spade quick-connect terminals to accommodate various wiring configurations. Common Questions: Can I use a 440V capacitor instead of this 370V model? Yes, you can safely use a 440V rated capacitor as long as the 4 MFD capacitance remains identical. However, you should never go lower than the original 370V rating. What are the signs of a failing CPT0076? Look for physical indicators like a bulging top (pressure relief activation), oil leakage, or electrical symptoms such as a humming motor that fails to start. Is this compatible with non-Trane systems? While designed for Trane, it is compatible with any HVAC motor requiring a 4 MFD 370V/440V oval run capacitor, provided physical dimensions align.
