The control board is the operational brain of your furnace: it sequences the inducer motor, hot surface igniter, gas valve, and PSC blower motor in precise coordination every time a heat call is made. When this board fails, symptoms range from a complete no-heat lockout and random mid-cycle shutdowns to blower-only operation or an igniter that energizes but never opens the gas valve. Fault codes displayed on the board's LED are your first diagnostic clue.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e HK42FZ040 | Factory-authorized Carrier replacement | Board part of the CEPL\/CEBD series IFC family | Compatible with single-stage hot surface ignition and PSC blower motor configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory-authorized board — not an aftermarket clone.
