Description
Trane CPT2523 Run Capacitor — 15 MFD / 450V
The Trane CPT2523 is a genuine OEM run capacitor engineered to deliver consistent, dependable performance in Trane HVAC systems. Rated at 15 microfarads (MFD) and 450 volts, this capacitor provides the electrical energy storage needed to start and sustain efficient motor operation in air conditioning and heat pump equipment.
Why Capacitors Matter
Capacitors are critical components in HVAC systems, supplying the phase-shifted current that motors require to start and run at peak efficiency. A failing or failed capacitor is one of the most common causes of compressor and fan motor failure. Replacing a worn capacitor with a genuine Trane part helps protect your investment and restore system performance quickly.
