Application
This capacitor is a direct OEM replacement designed for Trane air conditioning and heat pump systems. Run capacitors are critical to keeping motors running smoothly after startup — a failed or weak capacitor can cause compressor or fan motor failure, reduced efficiency, and system shutdowns. Replacing a worn capacitor with the correct OEM part helps restore full system performance and extends equipment life.
Installation Notes
- Always disconnect power before servicing capacitors
- Discharge capacitor safely before handling
