Rectorseal M12159 Dual Run Capacitor 65/5 Mfd 370V

Product Description

The RECTORSEAL M12159 is a dual run capacitor rated at 65/5 microfarads (MFD) and 370 volts, designed for use in residential and light commercial HVAC systems. Run capacitors provide the continuous phase shift needed to keep compressor and fan motors running efficiently after startup. This oval-style unit is sized to fit standard capacitor bays and is installed by licensed HVAC technicians during routine maintenance, motor replacement, or system repair. Its dual-rating design supports both the compressor and the condenser fan motor from a single component, reducing the number of parts in the electrical panel.

This capacitor is suited for split-system air conditioners and heat pumps where a single dual run capacitor serves both the compressor and outdoor fan motor circuits. It is a common replacement component during cooling-season service calls when a motor fails to start, runs hot, or draws excessive amperage. The oval form factor fits most standard condenser unit capacitor brackets.

Key Features

• Dual rating of 65 MFD and 5 MFD supports compressor and fan motor from one unit
• 370-volt rating suitable for standard residential and light commercial condensing units
• Oval form factor fits common condenser unit mounting brackets
• Compact dimensions allow installation in tight electrical compartments

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 65/5 MFD 370-volt oval capacitor.

Installation Notes

Dual run capacitors are installed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before opening the electrical access panel. Capacitors store a charge and must be safely discharged before handling, even after power is removed. Follow local electrical codes and manufacturer wiring diagrams when connecting capacitor terminals.
