Lennox 60M27 Ignition Module

The Lennox 60M27 Ignition Module is a critical OEM furnace control board engineered for high-reliability sequence management in gas-fired heating systems. This hot surface ignition (HSI) controller, also identified under the part number 60M2701 and the 1018 series, is designed to handle 120/240V output requirements common in residential and light commercial HVAC replacement parts. As a veteran-grade ignition control module, it manages the inducer motor, monitors flame rectification, and executes precise timing for the igniter warm-up and gas valve energization. Its advanced circuitry is specifically tuned for Lennox 60M27 troubleshooting, often resolving intermittent ignition issues or persistent furnace lockout codes that result from failed internal relays or sensor degradation in older 1018-525-I units.

• Direct OEM Compatibility: Engineered as a drop-in 60M2701 replacement, ensuring terminal alignment and harness fitment for Lennox and Armstrong units.
• Enhanced Safety Logic: Features integrated watchguard timing to prevent hazardous gas accumulation during failed ignition attempts.
• Universal Power Handling: Rated for both 50Hz and 60Hz applications with dual-voltage output capabilities for 120V and 240V configurations.
• System Diagnostic Support: Simplifies field diagnostics by providing clear feedback through existing system LED diagnostic codes.

Is the 60M27 compatible with the 60M2701?
Yes, the 60M27 is identical to the 60M2701. They are the same technical component and are interchangeable in all Lennox furnace applications calling for either part number.

How do I troubleshoot a 60M27 ignition failure?
Verify 120V at the "L" and "N" terminals. If the inducer starts but no spark or HSI glow occurs, check the flame sense rod for carbon buildup or inspect the hot surface igniter for cracked filaments before concluding the module has failed.

What causes a furnace lockout on this module?
Repeated failed ignition trials, typically caused by low gas pressure, a restricted exhaust vent, or a failing pressure switch, will trigger a hard lockout to protect the heat exchanger.
