OEM Lennox Integrated Furnace Control Board Kit — 68M28

The genuine OEM Lennox 68M28 integrated furnace control board kit is the electronic brain of your Lennox gas furnace. It manages the ignition sequence, monitors safety limits and flame sensing, sequences the inducer and blower motors, and coordinates signals from the thermostat to deliver safe, reliable heating. This complete kit includes the hardware needed for a direct factory replacement.

Common failure symptoms: The furnace fails to ignite, short-cycles, or locks out; the blower runs continuously or not at all; flashing diagnostic error codes on the board; no response to thermostat calls for heat; or visible scorch marks and burnt relays on the board itself.

Why OEM matters: The furnace control board must match your unit's exact ignition timing, relay ratings, and safety logic. An OEM Lennox 68M28 board is programmed and pin-configured for your equipment, ensuring correct sequencing and full safety-circuit protection. Universal or aftermarket boards can misfire ignition, bypass critical safeties, or fail to communicate with variable-speed components. Genuine parts safeguard both performance and your Lennox warranty.
