Designed as a specific \u003cstrong\u003eOEM replacement part\u003c\/strong\u003e for Carrier, Bryant, and Payne equipment, this component provides the high-torque electrical storage necessary to start and run both the compressor and fan motors within a single, space-saving housing. With a dual rating of 40 microfarads for the compressor circuit and 5 microfarads for the fan motor, this unit handles up to 440 VAC, making it an ideal upgrade or direct replacement for older 370V or 440V capacitors. Built to exacting \u003cstrong\u003eHVAC motor run capacitor\u003c\/strong\u003e standards, it features a non-PCB dielectric fluid and a safety-focused pressure-sensitive interrupter to protect the system during extreme thermal conditions. This \u003cstrong\u003e40\/5 dual capacitor\u003c\/strong\u003e is rated for 60,000 service hours, ensuring long-term cycle life and mechanical reliability in residential and light commercial condenser units.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOptimized Compatibility:\u003c\/strong\u003e Direct drop-in replacement for part numbers HC98KA041, HC98JA041, and P291-4053RS, ensuring minimal downtime during field service.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-Action Performance:\u003c\/strong\u003e Simultaneously regulates the start and run cycles for both the compressor and condenser fan, maintaining consistent motor efficiency.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThermal Stability:\u003c\/strong\u003e Rated for operation from -40°C to 70°C, offering reliable performance in harsh outdoor environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafety Engineering:\u003c\/strong\u003e Features a patented internal pressure-sensitive interrupter and is UL recognized for maximum arc protection.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHertz Range:\u003c\/strong\u003e Fully operational on both 50Hz and 60Hz frequencies, meeting broad electrical specification requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use the P291-4054RS to replace a 370V capacitor?\u003c\/strong\u003e\u003cbr\u003e\nYes, you can always go up in voltage. Since this is a 440V rated component, it will safely replace a 370V unit of the same 40\/5 MFD capacitance, often providing improved service life due to the higher dielectric strength.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat are the physical dimensions for installation?\u003c\/strong\u003e\u003cbr\u003e\nThis round dual capacitor typically measures approximately 5 inches in height with a 1.9 to 2.1-inch diameter, making it compatible with most standard residential condenser mounting straps.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I identify a failing 40\/5 MFD capacitor?\u003c\/strong\u003e\u003cbr\u003e\nCommon indicators include a \"bulged\" or swollen top at the terminals, a humming compressor that fails to start, or a fan motor that requires a manual push to begin rotating.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
