The board orchestrates all blower motor operations — managing fan speed sequencing, responding to thermostat signals, and coordinating the integrated time-delay relay. When this board fails, common symptoms include a blower fan that won't start, a fan that runs continuously without shutting off, erratic multi-speed operation, or a complete system lockout with no response to thermostat calls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Carrier OEM Part# HK61EA006 | Circuit board with integrated time-delay relay | Cross-references: CEPL130541-01, CEBD430541-03A, 1171734, 103972, 122621 | Compact module approx. 4.1″ × 4.2″ × 2.1″\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Factory Authorized Carrier part — not a third-party substitute.
