Rcd p291-1004 Run Capacitor 10 Mfd 370/440V Oval

Product Description

The RCD p291-1004 is a single-section oval run capacitor rated at 10 microfarads (MFD) and 370/440 volts AC, designed as an OEM-style replacement for residential and light commercial HVAC equipment. Run capacitors maintain a continuous phase-shifted current to motor windings, keeping compressor and fan motors running at rated efficiency after startup. This unit features a quick-connect terminal type and an aluminum construction, and carries a tolerance of plus or minus 5 percent on capacitance. Licensed HVAC technicians install this part during routine capacitor replacement service or as part of a no-cool diagnostic repair.

The p291-1004 is suited for split-system and packaged HVAC units where a single oval run capacitor is specified. It is compatible with Carrier packaged units including the 48DA 008 400, 48DA 008 100, and 48DA 008 110 among others. Its compact oval form factor and quick-connect terminals make it a direct drop-in candidate in equipment bays where space is limited. Always verify the MFD rating and voltage rating on the existing capacitor before substituting this part.

Key Features

• 10 MFD capacitance with a tight plus or minus 5 percent tolerance for consistent motor performance
• Dual-rated 370/440 volt AC for broad voltage compatibility in residential and light commercial systems
• Oval single-section design sized at 3.2 x 2.1 x 1.35 inches for compact equipment bays
• Quick-connect terminals allow fast, tool-light installation
• Aluminum construction rated from -40 to 70 degrees C for reliable operation across ambient extremes
• Compatible with 50/60 Hz power systems

Compatibility

Confirmed compatible with Carrier packaged units 48DA 008 400, 48DA 008 100, and 48DA 008 110. Additional model fitment may apply; consult the full fits-models list provided by the manufacturer to verify before ordering.

Installation Notes

Run capacitor replacement is performed by licensed HVAC technicians. Disconnect and lock out power to the unit before opening the electrical access panel, and discharge the existing capacitor fully before handling — stored charge can cause serious injury even with power off. Confirm the replacement MFD rating and voltage match the equipment nameplate or the existing capacitor label. Quick-connect terminals should seat firmly with no exposed conductors after installation.
