OEM Lennox Start Capacitor — 44A93

The genuine OEM Lennox 44A93 start capacitor delivers the high burst of electrical energy needed to get your compressor or motor spinning at startup. Built to Lennox specifications, it provides the correct microfarad rating and voltage tolerance to overcome initial inertia and bring the motor up to running speed quickly and reliably. Proper starting torque reduces electrical strain and extends the life of the motor it serves.

When a start capacitor weakens or fails, the most common symptom is a motor that hums but won't start, or one that hesitates and draws excessive current on startup. You may also notice the compressor tripping the breaker, frequent short-cycling, a clicking sound from the contactor, or a system that fails to cool on hot days. A bulging or leaking capacitor is a clear sign of failure.

Using the OEM 44A93 ensures the capacitance and voltage rating exactly match what your Lennox equipment requires. An incorrectly rated aftermarket capacitor can under-power the motor, cause overheating, or fail prematurely, potentially damaging the motor windings. Choose the genuine Lennox part for a precise fit, dependable starts, and protection of the more expensive components in your system.
