Value Collection 12957 Dual Run Capacitor 15/5 Mfd 370V

Product Description

The VALUE COLLECTION 12957 is a dual run capacitor rated at 15/5 microfarads (MFD) and 370 volts, designed for use in single-phase motor circuits found in HVAC equipment. Dual run capacitors serve two motor windings simultaneously, typically the compressor and the condenser fan motor, storing and releasing electrical energy to maintain stable motor operation and efficient starting performance. At 2.625 inches tall and weighing 1 pound, this compact capacitor fits standard equipment footprints. HVAC technicians install this part during routine capacitor replacement or as part of a compressor or fan motor service call.

This capacitor is suited for residential and light commercial HVAC applications where a single dual run capacitor handles both compressor and condenser fan motor circuits. It is commonly installed in split-system air conditioners and heat pump condenser units. The 370-volt rating is standard for most residential condenser unit applications. Technicians working on equipment that has experienced motor starting failures, slow-starting compressors, or capacitor bulging will find this a direct-fit replacement option.

Key Features

• Dual run configuration handles two motor windings with one capacitor
• 15/5 MFD rating supports both compressor and condenser fan motor circuits
• 370-volt rating matches standard residential condenser unit requirements
• Compact 2.625-inch height fits tight equipment compartments
• Lightweight at 1 pound for easy single-hand installation

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial single-phase HVAC condenser units requiring a 15/5 MFD, 370-volt rating.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condenser unit before opening the electrical compartment. Capacitors retain a charge after power is removed — discharge the capacitor safely using an approved discharge tool before handling. Verify the MFD rating and voltage rating on the original capacitor before installing the replacement, and confirm all terminals are seated and insulated before restoring power.
