Trane Dual Run Capacitor

The Trane Dual Run Capacitor is a replacement motor run capacitor for residential and light commercial heating, air conditioning and heat pump systems. It combines two capacitors in one round can. One section serves the compressor and the other serves the condenser fan motor. This lets a single part support both motors in the outdoor unit. You may also see it called a dual run capacitor, dual capacitor, or compressor and fan motor capacitor.

Key Features:

• Dual-section design that supports the compressor and the condenser fan motor from one component
• Round can construction for standard mounting in the outdoor unit
• Designed to give motors steady running torque and efficient operation
• Terminal layout identifies the compressor, fan and common connections
• Available under Trane and American Standard part numbers, including CPT and SFCAP series, for direct replacement of the original capacitor

A weak or failed run capacitor can cause hard starting, humming, short cycling, a motor that fails to start, or a unit that runs inefficiently. Replacing the capacitor with the correct Trane part helps restore reliable system performance. Match the microfarad (MFD) rating and voltage rating of your original capacitor when choosing a replacement. Disconnect power and safely discharge the capacitor before servicing.
