Rectorseal M12072 Dual Run Capacitor 35/5 Mfd 370V

Product Description

The RECTORSEAL M12072 is a dual run capacitor rated at 35/5 microfarads (MFD) and 370 volts, designed for use in residential and light commercial HVAC systems. This oval-style capacitor supports both the compressor and the condenser fan motor from a single unit, reducing component count in the electrical compartment. It is installed by licensed HVAC technicians during routine service, compressor replacement, or capacitor failure calls. The compact oval housing fits standard capacitor brackets and is sized for typical condensing unit applications.

This capacitor is suited for split-system air conditioners and heat pumps where a single dual run capacitor serves the compressor and fan motor simultaneously. The 35/5 MFD rating covers a common pairing found across many residential condensing units. Its 370-volt rating makes it appropriate for standard single-phase 240-volt circuits typical in residential HVAC installations. Technicians often carry this capacitor rating as a standard stock item for summer service calls.

Key Features

• Dual run capacitor supports both compressor and condenser fan motor in one unit
• Rated 35/5 MFD for common residential compressor and fan motor pairings
• 370-volt rating compatible with standard single-phase residential circuits
• Oval housing fits standard capacitor mounting brackets in condensing units
• Compact footprint: 2.806 inches long, 1.806 inches wide, 4.25 inches tall

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 35/5 MFD, 370-volt oval capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before servicing the electrical compartment. Capacitors store a charge even after power is removed — discharge the capacitor safely using an appropriate resistive discharge tool before handling. Verify the MFD ratings and voltage rating match the nameplate requirements of both the compressor and fan motor before installing.
