Westinghouse 01-0084 Dual Run Capacitor 40/5 Mfd 370V

Product Description

The WESTINGHOUSE 01-0084 is a round dual run capacitor rated at 40/5 microfarads (MFD) and 370 volts, designed for motor run applications in split system air conditioners and heat pumps. This dual capacitance design supports both the compressor and condenser fan motor from a single unit, reducing parts count and simplifying installation. Licensed HVAC technicians install this capacitor as a direct replacement when the original unit has failed or shows degraded capacitance. It is a standard round form factor, making it compatible with typical capacitor mounting brackets found in residential condensing units.

This capacitor is intended for use in split system air conditioner and heat pump applications. The dual capacitance rating of 40 MFD and 5 MFD serves the compressor and fan motor circuits respectively within the same housing. It is suited for residential condensing units operating on 370-volt rated capacitor circuits. HVAC service technicians will find this a straightforward replacement for failed or out-of-tolerance run capacitors during seasonal maintenance or emergency service calls on S5BX and T5BX series systems.

Key Features

• Dual capacitance rating: 40 MFD and 5 MFD in a single round housing

• 370-volt rating suitable for standard residential split system circuits

• Round form factor fits standard condensing unit capacitor mounting brackets

• Supports both compressor and condenser fan motor from one component

• Direct OEM-style replacement reduces downtime during service calls

Compatibility

Specified for use with S5BX and T5BX series split system air conditioners and heat pumps.

Installation Notes

A licensed HVAC technician should install this capacitor. Disconnect and lock out all power to the condensing unit before handling any capacitor — stored charge can remain even after power is removed, so discharge the old capacitor safely before removal. Verify the replacement MFD ratings and voltage rating match the unit nameplate or OEM specifications before installation. Follow all applicable local electrical codes and manufacturer wiring diagrams when making terminal connections.
