Installation is moderate difficulty and best handled by a licensed HVAC technician: power down at the disconnect, photograph and transfer the wiring harness, and swap the board on its standoffs. No reprogramming required. Using the OEM board protects your system warranty and avoids the misfires common with universal boards. We stock this part and ship same-day on all orders placed before 3PM CST, so your repair stays on schedule.
