The Lennox 11X97 is a genuine OEM tandem scroll compressor assembly built for multi-stage Lennox cooling systems. A tandem assembly pairs two scroll compressors on a shared manifold, allowing the unit to match cooling output to load by staging capacity up or down. This improves part-load efficiency, comfort, and humidity control while reducing energy consumption — and this assembly is a direct factory replacement for compatible Lennox equipment.

Common Failure Symptoms

Loss of cooling on one or both stages
Compressor won't start or trips the breaker
Excessive noise, vibration, or knocking
Short-cycling or inability to hold setpoint on high demand
Tripped overload or persistent overheating

Why OEM Matters

The genuine Lennox 11X97 assembly arrives matched to the manifold, mounting, and electrical specifications your system requires. Non-OEM substitutes can disrupt staging logic, reduce capacity, and shorten service life. Selecting OEM preserves rated efficiency, ensures a proper fit, and safeguards your Lennox warranty.
