The genuine OEM Lennox Y5368 control module kit provides the electronic control assembly that manages sequencing, safety monitoring, and component operation within your Lennox HVAC equipment. Supplied as a complete kit with the module and required mounting and wiring hardware, it replaces a worn or failed original board and restores factory-programmed operation to your unit.

Common failure symptoms include the system failing to start, intermittent operation, ignition or sequencing lockouts, error or fault codes on the diagnostic display, unresponsive controls, or components such as the blower, igniter, or valve not energizing on a call. Electrical surges, moisture, and normal age are frequent causes of module failure.

Choosing the OEM Lennox Y5368 kit ensures the correct firmware, connector pinout, and safety logic engineered specifically for your Lennox model. Universal or salvaged boards may lack the proper programming and can bypass critical safeties, risking further equipment damage. The factory kit delivers a precise, code-compliant repair that keeps your Lennox system running reliably.

Frequently Asked Questions

Does this Control Board fit my Lennox OEM Lennox Control Module Kit — Y5368?

Yes. This is the factory-specified OEM control board for the Lennox OEM Lennox Control Module Kit — Y5368. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the control board on my Lennox OEM Lennox Control Module Kit — Y5368?

Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.

My HVAC system is completely dead. What could be wrong?

Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.

Is this control board compatible with Bryant or Payne too?

Many Lennox parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Lennox control board?

OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
