Capacitor, Dual Run, 35/5 uF, 440 Volt VAC, Round

Lennox by Mars® 89M74 Dual Run Capacitor – 35/5 MFD, 440V AC, Round The Lennox 89M74 is a dual-section motor run capacitor engineered for use in HVAC systems utilizing permanent split capacitor (PSC) motors. With a capacitance rating of 35/5 microfarads (MFD) and a voltage rating of 440V AC, this capacitor provides continuous-duty support to both the compressor and condenser fan motor circuits. Constructed with metallized polypropylene film and sealed in an aluminum case, the 89M74 includes a pressure-sensitive internal interrupter for overpressure protection. It features standard ¼" male quick-connect terminals and is UL 810 compliant for HVAC service applications. Technical Specifications: OEM Reference: Lennox 89M74 Capacitance: 35/5 MFD (μF) Voltage Rating: 440V AC Type: Dual run Shape: Round Terminals: ¼" male quick-connect Dielectric: Metallized polypropylene film Case Material: Aluminum Internal Protection: Pressure-sensitive interrupter Temperature Range: -40°C to +70°C Compliance: UL 810 certified Application Overview: Designed for dual-capacitance HVAC circuits using PSC motors. Provides dedicated support for both compressor and fan motor operation. Suitable for replacement in Lennox systems and other HVAC equipment requiring a 35/5 MFD, 440V round capacitor. Used in residential and light commercial air conditioning and heat pump units. Installation Guidelines: Disconnect system power and verify capacitor discharge before handling. Confirm both capacitance and voltage ratings match system requirements. Observe proper terminal orientation (C, FAN, HERM) during installation. Secure unit to avoid movement or vibration during system operation. Installation should be performed by qualified personnel and must comply with applicable electrical codes. The Lennox 89M74 offers reliable electrical support for dual motor operation in HVAC equipment. It is engineered to meet OEM specifications and withstand continuous-duty applications in demanding environments.
