Lennox 68J35 Run Capacitor

The Lennox 68J35 Run Capacitor is a high-performance 70/7.5 MFD 440VAC dual-purpose component engineered for heavy-duty HVACR applications. This OEM replacement capacitor is designed to stabilize electrical loads for both the compressor and the condenser fan motor, ensuring optimal torque and efficient motor cycling. As a direct match for the Lennox 68J3501, this round metal-can unit features a 440V rating, providing superior dielectric strength and heat dissipation compared to standard 370V alternatives. Built for the rigors of the field, it utilizes a standard triple-terminal configuration (Herm, Fan, and C) to simplify wiring during emergency service calls. Whether you are addressing a hard-starting compressor or a humming fan motor, this dual run capacitor provides the precise microfarad tolerance required to maintain Lennox HVAC equipment performance and prevent premature motor winding failure in high-ambient environments.

• Dual Capacitance Precision: Delivers a dedicated 70 MFD for the compressor and 7.5 MFD for the fan motor to ensure balanced electrical delivery.
• Enhanced Voltage Tolerance: The 440VAC rating allows this unit to replace 370V capacitors, providing a more robust buffer against voltage spikes.
• Direct OEM Compatibility: Verified as an identical replacement for part number 68J3501, eliminating guesswork during installation.
• Industrial-Grade Construction: Housed in a round metal casing designed for superior thermal management and internal pressure protection.

• Can I use the 68J35 to replace a 370V capacitor? Yes, a 440V capacitor like the Lennox 68J35 can always replace a 370V unit with the same MFD ratings, as it possesses a higher insulation breakdown threshold.
• What does the 70/7.5 MFD rating signify? This indicates a dual-run design where 70 microfarads support the compressor (Herm terminal) and 7.5 microfarads support the condenser fan (Fan terminal).
• Will this fix a humming outdoor unit? If the motor is humming but not turning, it often indicates the capacitor has lost its charge-storing capacity; replacing it with an OEM Lennox part frequently restores operation.
