Rcd p291-2054 Dual Run Capacitor 20+5 Mfd 440V Oval

Product Description

The RCD p291-2054 is a dual run capacitor designed to stabilize motor and compressor performance in residential and light commercial HVAC systems. Rated at 20+5 microfarads (MFD) with a 440V AC rating and a 50/60 Hz frequency range, this oval-shaped capacitor maintains steady voltage supply to both the compressor and fan motor simultaneously under continuous duty conditions. The aluminum case and polypropylene film dielectric construction support reliable operation across a wide temperature range. Licensed HVAC technicians install this part as a direct OEM-style replacement when diagnosing hard-start conditions, motor cycling issues, or failed capacitor readings on a multimeter.

This capacitor is suited for split-system air conditioners and heat pumps where a single dual-run capacitor serves both the compressor and condenser fan motor. It carries a quick-connect terminal configuration for straightforward field replacement. Compatible models listed in product documentation include 38GS 048 810, 50QYH018 400, and 38GS 036 800. Always verify MFD rating, voltage rating, and terminal configuration against the existing capacitor or equipment wiring diagram before installation.

• Quick-connect terminals support fast field replacement without soldering
• Rated for 50/60 Hz operation and a temperature range of -29 to 68 degrees C

Compatibility

Compatible models identified in product data include 38GS 048 810, 50QYH018 400, and 38GS 036 800. Verify capacitance, voltage rating, and terminal type against the original capacitor label or equipment documentation before installation.

Installation Notes

A licensed HVAC technician should perform capacitor replacement. Disconnect and lock out power to the unit at the disconnect box before opening the electrical compartment. Capacitors retain a charge after power is removed — discharge the capacitor safely using an insulated resistor tool before handling. Follow local codes and the equipment manufacturer wiring diagram when reconnecting quick-connect terminals.
