This board serves as the central brain of the heating system — orchestrating the ignition sequence, monitoring all safety inputs (pressure switches, limit switches, flame sensor), controlling inducer and blower motor speeds, and generating diagnostic fault codes when something goes wrong. When the control board fails, common symptoms include a furnace stuck in lockout, erratic on\/off cycling, a blower that runs continuously, or a system that simply produces no heat despite the thermostat calling for it.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e HK42FZ066 | Board ID: CEBD431102-04-RA | Genuine Carrier Factory Authorized Part — exact factory specifications, zero modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM boards carry precise firmware and relay ratings matched to Carrier's fault-detection logic.
