OEM Lennox Dual Run Capacitor — Y5330

The genuine OEM Lennox Y5330 dual run capacitor stores and delivers the electrical charge that starts and runs both the compressor and the condenser fan motor in your outdoor unit. This single dual-rated capacitor provides the phase shift both motors need to develop torque and run efficiently, making it one of the most important — and most commonly replaced — components in an air conditioner or heat pump.

Common failure symptoms: the outdoor fan won't spin (or only starts with a manual push), the compressor hums but won't start, the unit trips the breaker, warm air from the vents on a cooling call, or a visibly bulged, leaking, or swollen capacitor top. Capacitors weaken gradually with heat and age, so a failing one can cause hard starts long before it dies completely.

Why OEM matters: the Y5330 is rated for the specific microfarad (µF) and voltage values your Lennox unit requires. An incorrect rating causes hard starting, overheating, and premature compressor failure — the costliest part of the system. Installing the OEM Lennox capacitor ensures the exact electrical specs and terminal configuration for safe, dependable operation.
