Value Collection 12923 Motor Run Capacitor 45 Mfd

Product Description

The VALUE COLLECTION 12923 is a single-section motor run capacitor rated at 45 microfarads (MFD) and 370 volts, designed to support the start and sustained operation of single-phase AC motors in HVAC equipment. Motor run capacitors provide the phase shift needed to keep PSC (permanent split capacitor) motors running efficiently after startup. This unit measures 3.75 inches in height and weighs approximately 0.07 pounds. It is a standard replacement component installed by licensed HVAC technicians during routine maintenance or compressor and fan motor service calls.

This capacitor is suited for use with single-phase PSC motors found in residential and light commercial HVAC systems, including condenser fan motors and blower motors. At 45 MFD and 370 volts, it falls within a common rating range for outdoor condensing unit fan motors. Installation is appropriate wherever the equipment manufacturer specifies a 45 MFD, 370-volt run capacitor in a round single-section form factor.

Key Features

• 45 MFD capacitance rating for sustained single-phase motor operation
• 370-volt AC rating suitable for standard residential HVAC applications
• Compact round form factor at 3.75 inches tall for space-limited equipment cabinets
• Lightweight at 0.07 pounds for easy handling during service
• Single-section design for straightforward terminal connection

Compatibility

Designed as an OEM-style replacement motor run capacitor for single-phase PSC motors requiring a 45 MFD, 370-volt single-section round capacitor.

Installation Notes

Motor run capacitors must be installed by a qualified HVAC technician. Always disconnect and lock out power to the unit before handling capacitors, as they can retain a dangerous charge even after the system is de-energized - discharge the capacitor safely before removal. Verify that the MFD rating, voltage rating, and physical form factor match the original equipment specification before installing. Follow all applicable local electrical codes and the equipment manufacturer's service instructions.
