OEM Carrier Control Board Replacement for Model LC748LCCSRMY2600

This genuine OEM Carrier control board acts as the brain of your HVAC system, coordinating ignition, blower and fan operation, safety lockouts, and communication with the thermostat. Built as a direct-fit replacement for the Carrier LC748LCCSRMY2600, it arrives with the correct factory programming and connector layout so your equipment resumes accurate, code-compliant function immediately. Symptoms of a bad board include flashing diagnostic LEDs, failure to ignite, a blower that won't engage, and random mid-cycle shutoffs, all of which a fresh board typically clears at once. This is a moderate DIY project for a careful homeowner or technician: kill power at the disconnect, photograph each harness, transfer the plugs one by one into the matching ports, and confirm the dip-switch settings copy the original. Discharge static electricity before handling. Genuine Carrier boards protect your warranty and eliminate the fitment guesswork of aftermarket universal boards. In stock and shipping same-day on orders placed before 3PM CST.

Frequently Asked Questions

Does this Control Board fit my Carrier Model LC748LCCSRMY2600?
Yes. This is the factory-specified OEM control board for the Carrier Model LC748LCCSRMY2600. 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 Carrier Model LC748LCCSRMY2600?
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 Carrier 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 Carrier 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.
How fast does National HVAC Parts ship?
