Rcd p291-0404 Run Capacitor 4 Mfd 370-440V Oval

Product Description

The RCD p291-0404 is a single oval run capacitor rated at 4 microfarads (MFD) and 370-440 volts AC, designed for use in residential and light commercial HVAC condensing units. Constructed with an aluminum housing, it provides the phase-shift current needed to keep the compressor or fan motor running efficiently after startup. Operating across a frequency range of 50/60 Hz, the p291-0404 suits a wide range of equipment. Quick-connect terminals allow for straightforward field replacement by licensed HVAC technicians servicing air conditioning and heat pump systems.

This capacitor is suited for condensing unit applications where a single oval run capacitor is required. It is a commonly specified replacement component in residential split-system air conditioners and heat pump outdoor units. Compatible equipment includes Carrier condensing unit models 38GC 005 330, 38GC 005 300, and 38GC 005 310, among others. Always verify capacitance, voltage rating, and physical dimensions against the original capacitor before installation.

Key Features

• 4 MFD capacitance with a tight plus or minus 6 percent tolerance for consistent motor performance
• 370-440V AC dual voltage rating accommodates standard residential and commercial supply voltages
• Oval aluminum housing measuring 4.3 x 4.15 x 1.65 inches for compact installation in tight equipment cabinets
• Quick-connect terminals simplify removal and reinstallation without special tooling
• Wide temperature rating of -40 to 70 degrees C supports reliable operation across climate extremes
• 50/60 Hz compatibility makes this capacitor suitable for both domestic and international equipment

Compatibility

Compatible with Carrier condensing unit models 38GC 005 330, 38GC 005 300, and 38GC 005 310. Additional compatible models may apply; consult the full fits-models list provided by the equipment manufacturer or distributor to confirm fitment before installation.

Installation Notes

Capacitor replacement is a task for a licensed HVAC technician. Disconnect and lock out all power to the condensing unit before servicing, and discharge the existing capacitor fully before handling, as capacitors retain a lethal charge even after power is removed. Confirm that the replacement capacitor matches the original MFD rating, voltage rating, and physical size. Follow all applicable NEC requirements and local codes when servicing electrical components in HVAC equipment.
