Carrier P291-3554RS Dual Run Capacitor 35/5 Mfd 440V

Product Description

The CARRIER P291-3554RS is a dual run capacitor rated at 35/5 microfarads (MFD) and 440 volts AC, designed for use in residential and light commercial HVAC systems. This round capacitor serves two functions in a single housing: it provides run capacitance for both the compressor and the condenser fan motor simultaneously. Licensed HVAC technicians install this part as a direct replacement when a failed or weakened capacitor causes hard-start conditions, motor overheating, or system shutdown. Its 440 VAC rating gives it broad voltage tolerance across common single-phase equipment.

This capacitor is a standard replacement component in split-system air conditioners and heat pumps where a single dual run capacitor supports both the compressor and outdoor fan motor. It is commonly installed during seasonal tune-ups, no-start diagnostics, or compressor replacement jobs. The round form factor is one of the most widely used configurations in residential condensing units, making this a practical stock item for field technicians and service shops.

Key Features

• Dual run design powers compressor and condenser fan motor from one capacitor
• 35/5 MFD rating covers the most common compressor-plus-fan capacitor combination
• 440 VAC rating provides compatibility with standard single-phase residential and light commercial equipment
• Round form factor fits widely used capacitor mounting brackets and disconnect enclosures
• Sold individually despite bulk packaging, allowing single-unit replacement purchases

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 35/5 MFD, 440 VAC round capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Disconnect and lock out all power to the condensing unit before opening the electrical compartment. Capacitors store a charge even after power is removed and must be safely discharged using an insulated discharge tool before handling. Follow NEC guidelines and local codes for low-voltage and line-voltage wiring in HVAC equipment.
