Lennox 71G12 Rollout Switch 210°F M/R SPST

The Lennox 71G12 is a manual reset rollout safety switch designed for use in Lennox gas furnaces and heating equipment. This SPST (Single Pole Single Throw) switch is calibrated to open at 210°F, providing critical overheat protection by shutting down the burner when excessive temperatures are detected in the burner compartment or flue area.

Key Features:

• 210°F temperature rating for reliable overheat detection
• Manual reset operation requires technician intervention after tripping
• SPST switching configuration for straightforward installation
• Genuine Lennox OEM replacement part ensures proper fit and function
• Designed to mount directly in the rollout sensing area of compatible furnaces

This rollout switch serves as an essential safety device that prevents dangerous conditions caused by flame rollout or improper venting. When the switch trips due to excessive heat, it must be manually reset after the underlying cause has been identified and corrected by a qualified HVAC technician.
