OEM Lennox Dual Run Capacitor — 68J35

The genuine OEM Lennox 68J35 dual run capacitor provides the electrical charge needed to start and run both the compressor and condenser fan motor in your Lennox outdoor unit. This single component handles two loads at once, delivering the phase shift required for efficient motor operation and steady voltage under demand. It is a direct factory replacement engineered to the exact microfarad and voltage ratings your Lennox system expects.

Capacitors are among the most common HVAC failure points. When the 68J35 weakens or fails, you may notice a humming compressor that won't start, a condenser fan that spins slowly or not at all, hard starting, frequent breaker trips, or intermittent cooling. A bulging or leaking capacitor top is a clear sign of failure and should be replaced immediately.

Choosing OEM matters for Lennox equipment. An out-of-spec aftermarket capacitor can undersupply or overstress your motors, shortening their life and voiding coverage. The 68J35 guarantees correct capacitance, tolerance, and terminal configuration for a reliable, drop-in fit that restores your system to rated performance.
