Rectorseal M12031 Run Capacitor 7.5 Mfd 440V Oval

Product Description

The RECTORSEAL M12031 is an oval run capacitor rated at 7.5 microfarads (MFD) and 440 volts, designed for use in single-phase motors found in HVAC equipment. Run capacitors provide the continuous phase shift needed to keep PSC motors running efficiently after startup. This capacitor maintains a steady energy charge during motor operation, helping the motor run at correct torque and speed. Licensed HVAC technicians are the primary installers of this component during compressor, condenser fan, or air handler blower motor service. Its compact oval form factor fits standard capacitor brackets in most residential and light commercial equipment.

This capacitor is suited for condenser fan motors, blower motors, and compressors in residential and light commercial air conditioning and heat pump systems. The 440-volt rating allows it to be used in both 208-volt and 240-volt single-phase motor applications, giving technicians a single replacement part that covers a wide range of equipment in the field. It fits standard oval capacitor mounting hardware commonly found in split-system outdoor units and air handler cabinets.

Compatibility

Designed as an OEM-style replacement run capacitor for single-phase PSC motors in residential and light commercial HVAC systems requiring a 7.5 MFD 440-volt oval capacitor.

Installation Notes

Run capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the unit before handling capacitors, as they can retain a dangerous charge even after power is removed — discharge the capacitor safely using an insulated resistor before touching terminals. Verify the MFD rating and voltage rating of the original capacitor before installing a replacement. Follow applicable local electrical codes and equipment manufacturer wiring diagrams during installation.
