It continuously reads the flame sensor, high-limit switch, and pressure switch, then drives the gas valve and indoor blower to deliver reliable, efficient heat. Symptoms of a bad board include no heat call response, short cycling, blower that won't shut off, or flashing fault codes at the diagnostic LED. As a factory-direct replacement, it shares the exact connector layout and control logic of the original, so installation requires no splicing or reconfiguration. The job is moderate in difficulty: disconnect power, snap a photo of the harness, move each plug to the new board, and secure it to the existing mounting posts — typically 20-30 minutes. Choosing OEM protects your Carrier warranty and prevents the erratic timing seen with universal boards. This item is in stock and ships same-day on orders placed before 3PM CST.
