OEM Lennox Ignition Control Board — 60M32

The genuine OEM Lennox 60M32 ignition control board is the electronic brain that manages your furnace's startup sequence — energizing the inducer, proving the pressure switch, powering the igniter, opening the gas valve, and confirming flame through the sensor. Built to Lennox firmware and wiring specifications, it coordinates every safety and timing step so your furnace lights reliably and shuts down safely on any fault.

A failing control board often shows up as no ignition despite a call for heat, erratic or intermittent starts, blinking diagnostic LED fault codes, a furnace that runs the blower but never fires, or complete loss of control power. Heat, voltage surges, and corroded relays can degrade the board over time, leaving you with unpredictable heating.

OEM matters because the 60M32 is matched to your Lennox model's ignition type, timing sequence, and connector pinout — an incorrect or aftermarket board can misfire the sequence, bypass safeties, or fail to communicate with other components. The factory board plugs into the existing harness for a precise fit and restores the exact, safety-verified ignition control your Lennox furnace was engineered to use.
