Value Collection 12963 Dual Run Capacitor 20/5 Mfd 370V

Product Description

The VALUE COLLECTION 12963 is a dual run capacitor rated at 20/5 microfarads (MFD) and 370 volts, designed for use in single-phase HVAC motor circuits. Dual run capacitors serve two motor windings simultaneously — typically the compressor and the condenser fan motor — from a single cylindrical housing. This unit stands 2.625 inches tall and weighs 1 pound, making it a compact, direct-swap solution for failed or degraded capacitors in residential and light commercial cooling equipment. Licensed HVAC technicians install this part as part of routine seasonal maintenance or in response to hard-start or no-start compressor conditions.

This capacitor is suited for split-system air conditioners and heat pumps that use a shared dual run capacitor for the compressor and fan motor circuits. It is commonly installed in condensing units where the original capacitor has tested outside acceptable MFD tolerance or shows signs of bulging, leakage, or voltage breakdown. The 370-volt rating makes it appropriate for standard residential single-phase compressor and fan motor applications operating on 208/230-volt circuits.

Key Features

• Dual run design supports two motor windings from a single unit — compressor and condenser fan
• Rated at 20/5 MFD to match common OEM compressor and fan motor capacitor requirements
• 370-volt rating suitable for 208/230-volt single-phase residential HVAC circuits
• Compact cylindrical housing at 2.625 inches tall for straightforward cabinet fitment
• Lightweight at 1 pound for easy handling during rooftop or ground-level condenser service

Compatibility

Designed as an OEM-style replacement for residential and light commercial condensing units that require a dual run capacitor with a 20/5 MFD rating at 370 volts.

Installation Notes

Dual run capacitors must be installed by a licensed HVAC technician. Before servicing, disconnect and lock out power to the condensing unit at the disconnect box and verify zero voltage at the capacitor terminals using a calibrated multimeter — capacitors store a charge even after power is removed. Match the MFD ratings and voltage rating exactly to the original component; a capacitor with a lower voltage rating must not be substituted. Refer to the equipment manufacturer's wiring diagram for terminal identification (HERM, FAN, COM).
