Description
The Lennox 10G90 is an OEM-grade 180°F control limit designed to protect Lennox furnace systems from dangerous overheating conditions. Acting as a critical safety device, this high-limit control monitors supply-air or heat exchanger temperatures and interrupts the burner circuit when temperatures reach the preset 180°F threshold — preventing equipment damage, nuisance shutdowns, and potential safety hazards.
