Rectorseal M12066 Dual Run Capacitor 25/5 Mfd 370V Oval

Product Description

The RECTORSEAL M12066 is a dual run capacitor rated at 25/5 microfarads (MFD) and 370 volts, designed for use in residential and light commercial HVAC systems. It provides the starting and running support that compressors and condenser fan motors require to operate efficiently. The oval form factor fits standard condensing unit capacitor brackets. HVAC technicians install this capacitor as a direct replacement when a failed or weak capacitor causes hard-start conditions, motor humming, or compressor drop-out on a cooling call.

This capacitor is suited for split-system air conditioners and heat pumps where a single oval capacitor serves both the compressor and the condenser fan motor. The 25 MFD winding supports the compressor, while the 5 MFD winding supports the fan motor. Its compact oval housing at approximately 1.806 inches wide, 2.806 inches long, and 3.125 inches tall fits inside most standard condensing unit control compartments without modification.

Key Features

• Dual-run design: 25 MFD compressor winding and 5 MFD fan motor winding in one housing
• 370-volt rating suitable for standard residential condensing unit circuits
• Oval form factor fits common capacitor mounting brackets in condensing units
• Compact dimensions: 1.806 inches wide, 2.806 inches long, 3.125 inches tall
• Direct OEM-style replacement reduces callbacks and simplifies truck-stock management

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 25/5 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 at the disconnect box before handling capacitors. Capacitors store a lethal charge even after power is removed — discharge the existing capacitor through a resistor before touching terminals. Follow NEC guidelines for low-voltage and high-voltage work within the unit's control and compressor compartment.
