Motors and Armatures 12071 Dual Run Capacitor 35 4 Mfd

Product Description

The MOTORS AND ARMATURES 12071 is a dual-section motor run capacitor rated at 35 MFD and 4 MFD, designed for use in residential and light commercial HVAC systems. Dual run capacitors house two capacitance values in a single can, allowing one unit to support both the compressor and the condenser fan motor simultaneously. This design reduces the number of components in the electrical panel and simplifies replacement. Licensed HVAC technicians are the primary installers of this type of capacitor during routine maintenance, compressor start failures, or fan motor replacements.

This capacitor is suited for split-system air conditioners and heat pumps where a single dual-section unit serves both the compressor and outdoor fan motor. The Base C mounting style allows secure installation within the condensing unit cabinet. It is a direct-replacement style component commonly found in residential systems and select light commercial applications where space and component count in the electrical section are factors.

Key Features

• Dual-section design combines 35 MFD and 4 MFD ratings in one unit
• Base C mount for secure, stable installation in condensing unit cabinets
• Reduces component count by supporting both compressor and fan motor from a single capacitor
• OEM-style replacement form factor for straightforward swap-out service

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 35/4 MFD dual-section capacitor with Base C mounting.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before opening the electrical panel. Capacitors retain a charge even after power is removed — use an insulated discharge tool to safely discharge the capacitor before handling. Follow local codes and NEC requirements for electrical component replacement in HVAC equipment.
