The board serves as the central command module for blower operation — managing fan speed sequencing, time delay relay functions, and cooling\/heating fan activation signals from the thermostat. When this board fails, common symptoms include the blower not starting in cooling mode, the fan running continuously even with the thermostat off, coil freeze-up due to improper airflow control, or the system short-cycling with no airflow response. Replacing this board with the correct OEM part restores factory-programmed timing and relay logic.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HK61EA006 | Also cross-references CEPL130541-01, 1171734, 103972, 122621 | Includes integrated time delay relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM board with factory-programmed timing sequences and relay specifications.
