Rectorseal M12149 Dual Run Capacitor 35/7.5 Mfd 370V Oval

Product Description

The RECTORSEAL M12149 is a dual run capacitor rated at 35/7.5 MFD and 370 volts, designed for use in residential and light commercial HVAC systems. Dual run capacitors serve two motor loads simultaneously — typically the compressor and the condenser fan motor — from a single oval-shaped housing. This configuration reduces the component count inside the unit and simplifies replacement during a service call. The oval form factor fits standard capacitor brackets found in most condensing units. Licensed HVAC technicians and refrigeration mechanics are the primary installers of this component.

This capacitor is suited for split-system air conditioners and heat pumps where a single capacitor must support both the compressor and the outdoor fan motor. The 370-volt rating covers the supply voltage range common in single-phase residential condensing equipment. The oval housing measures 1.806 inches wide by 2.806 inches long by 3.5 inches tall, making it a compact fit for tight electrical compartments in outdoor units.

Key Features

• Dual run design supports compressor and condenser fan motor from one capacitor
• 35/7.5 MFD dual capacitance rating for two independent motor loads
• 370-volt rating compatible with standard single-phase residential supply voltages
• Oval housing fits most standard capacitor mounting brackets in condensing units
• Compact dimensions allow installation in space-constrained electrical compartments

Compatibility

Designed as an OEM-style replacement dual run capacitor for single-phase residential and light commercial air conditioning and heat pump condensing units requiring a 35/7.5 MFD, 370-volt oval capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit before opening the electrical compartment. Capacitors store a lethal charge even after power is removed — discharge the capacitor fully using an approved discharge tool before handling or disconnecting terminals. Verify the MFD rating and voltage rating of the replacement match the original unit nameplate specifications before installing.
