OEM Lennox Copeland Scroll Compressor — 11C46

The genuine OEM Lennox 11C46 Copeland scroll compressor drives the refrigeration cycle in your Lennox condensing or heat pump unit, compressing refrigerant vapor to reject heat and deliver dependable cooling. Its Copeland scroll design offers high efficiency, low vibration, and long-term durability, making it a direct factory-matched replacement that restores your Lennox system to its designed performance.

When the 11C46 starts to fail, watch for symptoms such as a compressor that buzzes or hums without starting, frequent breaker trips, excessive noise or vibration, weak or no cooling output, and short-cycling. Overheating, an open internal overload, or a locked scroll set are common indicators that replacement is required.

Because the compressor is the single most valuable component in the outdoor unit, OEM matters. The Lennox 11C46 is specified for your system's exact capacity, voltage, and refrigerant, ensuring the correct oil type and charge, proper connector fit, and full compatibility with your unit's start components and controls. Installing the genuine part safeguards efficiency, supports warranty compliance, and delivers the reliable service life you expect from Lennox equipment.
