Nortek Global Hvac 01-0274 Dual Run Capacitor 55/7.5 Mfd 370V

Product Description

The NORTEK GLOBAL HVAC 01-0274 is a dual run capacitor rated at 55/7.5 microfarads (MFD) and 370 volts, designed for use in residential and light commercial HVAC systems. Dual run capacitors serve two motor circuits simultaneously, typically supporting both the compressor and the condenser fan motor from a single round capacitor housing. This round-style unit provides stable capacitance to maintain motor start and run efficiency. Licensed HVAC technicians install this component as a direct replacement during routine service or when diagnosing motor starting failures in split-system air conditioners and heat pumps.

This capacitor is suited for split-system condensing units where a single round dual capacitor powers the compressor and the outdoor fan motor. The 55 MFD section supports the compressor, while the 7.5 MFD section supports the condenser fan motor. At 370 volts, it is compatible with standard single-phase residential condensing unit applications. It is a common service replacement for systems exhibiting slow-start symptoms, humming motors, or compressor short-cycling caused by a failed or degraded capacitor.

Key Features

• Dual capacitance rating: 55 MFD for the compressor circuit and 7.5 MFD for the fan motor circuit
• 370-volt rating suitable for standard single-phase residential HVAC applications
• Round housing simplifies drop-in replacement in existing capacitor brackets
• Single-unit design replaces two separate capacitors, reducing parts count on service calls

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioning and heat pump condensing units requiring a 55/7.5 MFD 370-volt round capacitor.

Installation Notes

Installation of run capacitors must be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the condensing unit before handling any capacitor, and discharge the existing capacitor fully before removal, as capacitors can hold a dangerous charge even after power is cut. Verify the MFD ratings and voltage rating of the replacement match the original unit nameplate specifications before installing. Follow applicable NEC requirements for service and replacement of electrical components in HVAC equipment.
