OEM Lennox Integrated Furnace Control Board Kit — Y4152

The genuine OEM Lennox Y4152 integrated furnace control (IFC) board kit is the electronic brain of your furnace, coordinating ignition sequencing, blower timing, gas valve operation, and critical safety limits. This complete kit includes the factory-programmed board and mounting hardware needed for a clean, direct replacement in compatible Lennox gas furnaces, restoring precise, code-compliant heating control.

When an integrated control board fails, the furnace often stops responding entirely or behaves erratically. Common symptoms include no ignition, a blower that runs constantly or not at all, flashing fault codes on the diagnostic LED, intermittent no-heat calls, and a system that locks out after failed ignition attempts. Heat-stressed relays, cracked solder joints, and surge-damaged traces are typical failure points on aging boards.

OEM matters most on control electronics. The Y4152 carries Lennox factory firmware and timing profiles matched to your furnace's ignitor, gas valve, and blower, so ignition sequences and safety lockouts function exactly as engineered. Aftermarket boards can miscommunicate with Lennox components, causing nuisance faults or unsafe operation. Install this OEM kit for guaranteed compatibility and dependable heat.
