The control board governs blower operation, relay switching, fan timing, and built-in safety interlocks in response to thermostat demand.

Manufactured to Carrier factory standards, this board delivers the exact connector arrangement, relay layout, and control logic of the original, ensuring proper operation and communication across the unit. Installation is moderate to advanced in difficulty and best performed by a qualified HVAC technician: disconnect power, photograph and transfer each harness to the corresponding terminals, secure the new board, and confirm correct operation. Professional installation is strongly recommended. Orders placed before 3PM CST ship same-day to keep downtime short.
