Lennox 17G85 Gen2 Inverter — XC/XP20-060 Replacement
The Lennox 17G85 is a second-generation inverter drive designed as a direct OEM replacement for Lennox XC20 and XP20 series 060 (5-ton) air conditioners and heat pumps. This inverter module is a critical component of Lennox’s variable-speed compressor technology, enabling precise modulation of compressor speed to match the exact cooling or heating demand of the space. The result is superior efficiency, enhanced comfort, and reduced energy consumption compared to single- or two-stage systems.
Key Features

Application
The 17G85 inverter is intended for use in Lennox XC20 and XP20 model 060 outdoor units. The XC20 is a premium variable-capacity central air conditioner, while the XP20 is the heat pump counterpart — both representing Lennox’s top-tier residential comfort systems. When the inverter fails or degrades, replacing it with the genuine Lennox 17G85 Gen2 unit restores full variable-speed operation and system efficiency.
