Capacitor, Dual Run, 35/5 uF, 370 Volt VAC, Round

Lennox by Mars® 89M73 Dual Run Capacitor – 35/5 MFD, 370V AC, Round The Lennox 89M73 is an OEM-specified dual run capacitor designed for HVAC systems using permanent split capacitor (PSC) motors. With a capacitance of 35/5 microfarads (μF) and a voltage rating of 370V AC, this component supports continuous-duty operation for both compressor and condenser fan motors within Lennox air conditioning or heat pump systems. Constructed with metallized polypropylene film dielectric in a round aluminum case, the 89M73 includes a pressure-sensitive internal interrupter for overpressure protection. It uses ¼" male quick-connect terminals and is built to meet UL 810 performance and safety standards. Technical Specifications: Manufacturer: Mars® OEM Reference: Lennox 89M73 Capacitance: 35/5 MFD (μF) Voltage Rating: 370V AC Shape: Round Terminal Type: ¼" male quick-connect Dielectric: Metallized polypropylene film Enclosure: Aluminum Temperature Range: -40°C to +70°C Interrupter Type: Pressure-sensitive internal interrupter Compliance: UL 810 certified Application: PSC motors in Lennox HVAC systems Application Overview: Supports dual-motor systems requiring independent capacitance to compressor and fan circuits. Intended for Lennox OEM installations and as a direct replacement part in systems calling for 35/5 MFD, 370V capacitors. Suitable for residential and light commercial HVAC units using round-style capacitors. Installation Notes: Disconnect all power and verify capacitor discharge before service. Match both microfarad and voltage ratings with existing equipment specifications. Terminals are marked for correct wiring: “C” (common), “FAN,” and “HERM” (compressor). Mount capacitor securely and protect from vibration and moisture exposure. Installation should be performed by licensed professionals in accordance with applicable electrical codes. The 89M73 dual run capacitor provides reliable power delivery and system support for Lennox HVAC applications. Its OEM specification ensures consistent performance in new installs and replacement work.
