Motors and Armatures 12085 Oval Run Capacitor 35+3 Mfd 440V

Product Description

The MOTORS AND ARMATURES 12085 is a dual-run capacitor rated at 35 plus 3 microfarads (MFD) and 440 volts, designed for use in split-system air conditioners, heat pumps, and similar HVAC equipment. Run capacitors provide the continuous phase-shifted current that keeps compressor and fan motors operating at full efficiency throughout the run cycle. The oval form factor is a common OEM-style profile that fits standard capacitor brackets and mounting straps found in most residential and light commercial condensing units. HVAC technicians routinely replace these as part of a compressor or condenser fan motor service call.

This capacitor is suited for residential and light commercial HVAC applications where a dual-rated 35 plus 3 MFD, 440-volt oval capacitor is specified. The 35 MFD section typically serves the compressor while the 3 MFD section serves the condenser fan motor, consolidating two capacitors into a single component. It is installed inside the condensing unit control compartment and is a frequent replacement item during seasonal maintenance and no-cool service calls.

Key Features

• Dual-rated capacitance: 35 MFD for compressor and 3 MFD for condenser fan motor
• 440-volt rating provides compatibility across a wide range of residential and light commercial condensing units
• Oval form factor fits standard capacitor brackets and mounting straps
• Single component replaces two separate run capacitors, simplifying the service call

Compatibility

Designed as an OEM-style replacement run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a dual 35 plus 3 MFD, 440-volt oval run capacitor.

Installation Notes

Run capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit at the disconnect block before opening the control compartment. Capacitors store a charge even after power is removed — discharge the capacitor safely using an insulated resistor tool before handling terminals. Follow NEC guidelines for low-voltage and high-voltage wiring practices when reconnecting terminals.
