Value Collection 12921 Motor Run Capacitor 40 Mfd 370V

Product Description

The VALUE COLLECTION 12921 is a single-section motor run capacitor rated at 40 microfarads (MFD) and 370 volts. Motor run capacitors maintain a continuous phase shift in single-phase AC motors, improving torque and efficiency throughout the run cycle. This capacitor is sized for blower motors, condenser fan motors, and compressor-assist applications commonly found in residential and light commercial HVAC equipment. Licensed HVAC technicians and refrigeration mechanics are the primary installers. The oval or round can design is a direct field replacement when the original capacitor fails or tests out of tolerance.

This capacitor is suited for single-phase induction motors operating on 370-volt circuits, including condenser fan motors and air handler blower motors in split-system air conditioners and heat pumps. The 40 MFD rating is a common value found in both OEM and aftermarket capacitor applications across a wide range of residential cooling equipment. It is also used in light commercial rooftop units where single-phase motor starters require continuous capacitance support.

Key Features

• 40 MFD capacitance rating for steady-state motor run support
• 370-volt AC rating suitable for standard residential and light commercial circuits
• Compact form factor for tight equipment compartments
• Single-section design simplifies replacement and wiring

Compatibility

Designed as an OEM-style replacement for single-phase motor run capacitor applications in residential and light commercial HVAC systems requiring a 40 MFD, 370-volt rated capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the unit before servicing capacitors, and discharge the existing capacitor safely before handling or removing terminals. Capacitors can retain a lethal charge even after power is removed. Verify MFD rating and voltage rating match the motor nameplate before installing a replacement.
