The RECTORSEAL M12069 is a dual run capacitor rated at 30/5 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 fan motor from a single unit, reducing component count in the condensing unit. It provides the phase-shifted current needed to start and run PSC motors efficiently. HVAC technicians install this capacitor as a direct replacement during preventive maintenance or when diagnosing motor start or run failures in split-system air conditioners and heat pumps.
This capacitor is suited for installation in outdoor condensing units where a single dual-run capacitor serves both the compressor and condenser fan motor. The oval form factor fits standard capacitor mounting brackets common in residential equipment. Technicians typically encounter this part during summer service calls when heat-related capacitor failure causes compressor or fan motor issues.
Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps using PSC compressor and fan motor configurations.
Installation should be performed by a licensed HVAC technician. Disconnect and lock out power to the condensing unit before servicing any capacitor. Capacitors retain a charge even after power is removed — discharge the capacitor safely using an approved discharge tool before handling. Verify the MFD and voltage ratings match the equipment nameplate requirements before installing the replacement.
