Lennox 25M60 Rollout Switch

The Lennox 25M60 Rollout Switch is a critical safety component designed for precise thermal monitoring in residential and light commercial gas furnaces. This OEM Lennox replacement part features a factory-calibrated 210 degrees F trip point, ensuring the system shuts down immediately if a flame rollout condition is detected outside the heat exchanger. Engineered with a Single-Pole Single-Throw (SPST) configuration, the 25M60 rollout switch functions as a fail-safe to prevent hazardous heat accumulation within the burner vestibule.

For service technicians, this unit is a direct-fit solution that features a manual reset mechanism, requiring a physical inspection of the combustion blower and heat exchanger integrity before the system can be restored to operation. The 210F manual reset rollout switch is compatible with a wide range of Lennox, Allied, and Armstrong furnace models, including the G60UH and G61MPV series. Its SPST open face design with the distinct white dot identifier allows for quick identification and seamless integration into the existing safety string, maintaining the original equipment manufacturer's safety standards without the need for field modifications.

Key Benefits:

• Direct OEM Compatibility: Ensures seamless integration with Lennox furnace safety circuits and mounting brackets.
• High-Precision Thermal Protection: Actuates at 210 degrees Fahrenheit to mitigate fire risks during burner malfunctions.
• Mandatory Manual Reset: Forces a technician's inspection following a trip, preventing repeated cycling under unsafe conditions.
• Robust Construction: Built to withstand the high-cycle demands and ambient heat of modern furnace burner compartments.

Common Questions:

Why does my Lennox furnace rollout switch keep tripping?
A tripped Lennox 25M60 typically indicates a restriction in the flue, a cracked heat exchanger, or improper manifold pressure causing flames to "roll out" of the burner. Always inspect the venting and heat exchanger integrity before resetting.

Can I bypass the manual reset for testing?
Bypassing safety controls is strictly against code and manufacturer specifications. The manual reset rollout switch is designed to protect the equipment and structure; if it trips, the underlying combustion issue must be diagnosed by a professional.

How do I verify if the 25M60 is the correct part for my unit?
Cross-reference the 25M6001 or 97L02 part numbers with your furnace's service manual. This SPST switch is standard on many Lennox-built 80% and 90%+ AFUE gas furnaces.
