When you are out in the field and a compressor is struggling to kick over, the Trane CPT2328 is the specific HVAC start capacitor designed to provide that high-torque boost. This OEM replacement part is a 196 MFD 330V round capacitor that comes factory-integrated with a bleeder resistor. This resistor is a critical safety and performance feature, ensuring a controlled discharge of stored energy to prevent arcing and protect the internal contacts of your start relay. If you are servicing older American Standard or Trane units and see an existing Trane CPT1808, this is the direct manufacturer-specified upgrade. With a 330V rating, it provides substantial overhead for high-demand motor start applications in residential and light commercial condensers. The unit features standard 1/4-inch quick-connect terminals for a fast swap, getting your customer's system back online without fussing with wiring. This is an essential stock item for any tech handling Trane-specific service calls. Key Benefits Specifically engineered to replace discontinued Trane CPT1808 models with 100% mechanical and electrical compatibility. Features an integrated 2-watt bleeder resistor to safely discharge high-voltage energy between cycles. Robust 196 microfarad rating provides the necessary starting torque for aging compressors and high-head pressure starts. Heavy-duty 330 VAC rating ensures reliable performance under fluctuating line voltages. Compact round start capacitor design fits standard mounting straps in most Trane and American Standard control boxes. Common Questions Is the bleeder resistor required for this model? Yes, the Trane CPT2328 includes a pre-installed resistor. This prevents the start relay contacts from pitting or welding by dissipating the charge once the motor is up to speed. Can I use this to replace a capacitor with a lower voltage rating? As a veteran tech, you know you can always go up in voltage, but never down. This 330V capacitor is a safer, more durable replacement for older 320V or 250V start caps. Will this fit in the original CPT1808 bracket? This capacitor maintains the standard HVAC motor capacitor dimensions for its class, though always check the diameter in tight control cabinets to ensure the mounting strap provides a secure seat.
