Firstco E1504 Dual Run Capacitor 15/5 MFD 370V

The Firstco E1504 is an OEM dual run capacitor rated at 15/5 MFD (microfarads) at 370 volts, designed for use in residential and commercial HVAC systems. This capacitor provides continuous electrical support to both the compressor and the fan motor within a single round housing, helping maintain efficient and reliable system operation.

Key Features:

• Dual capacitance: 15 MFD for the compressor, 5 MFD for the fan motor
• Voltage rating: 370V AC
• Configuration: Dual run capacitor in a round form factor
• OEM replacement for First Company / Firstco HVAC equipment
• Three-terminal design with standard 1/4" male push-on terminals (HERM, FAN, COM)
• Suitable for air conditioners, heat pumps, and air handlers

Run capacitors like the E1504 are essential components in HVAC motor circuits, providing the phase shift needed to keep motors running smoothly after startup. Replacing a failed or weak run capacitor restores proper motor performance and prevents premature compressor or fan motor failure.
