The Lennox 60M61 is a manual reset rollout switch engineered to protect your furnace from the hazards of flame rollout. When burner flames extend beyond their normal combustion zone, this safety device detects the elevated temperature and immediately interrupts the circuit, shutting down the heating system before damage or fire can occur.
Key Features
- Trip temperature: 290°F — precisely calibrated to detect abnormal flame rollout conditions
- Manual reset operation — requires deliberate technician intervention before the system can restart, ensuring the root cause is identified and corrected
- SPST (Single Pole, Single Throw) switching configuration for straightforward circuit interruption
- Direct OEM replacement for compatible Lennox furnace models
- Durable construction designed to withstand the high-heat environment of a furnace heat exchanger compartment
Why Rollout Switches Matter
Flame rollout is a serious furnace safety concern that can result from a cracked heat exchanger, blocked flue, or restricted combustion air. The Lennox 60M61 acts as a critical last line of defense, cutting power to the burner circuit the moment temperatures exceed the 290°F threshold. Because this is a manual reset device, the furnace will not restart automatically — prompting a qualified technician to diagnose and repair the underlying issue before returning the system to service.
