OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNC018008AAAA

This is the OEM factory-specified fan blower control board for the Carrier PF1MNC018008AAAA air handler. The board governs all blower motor operations — including startup sequencing, multi-speed fan control, and the integrated time delay relay that protects your system from rapid cycling. When this board fails, common symptoms include a blower that won't start, a fan that runs continuously regardless of thermostat demand, erratic airflow speeds, or a complete loss of air movement while the rest of the system appears powered on. Replacing this board with the correct OEM part restores factory-precise control logic and timing.

• Part Number & Specs: Carrier OEM Part HK61EA006 | Includes integrated time delay relay | Cross-references: CEPL130541-01, CEBD430541-03A, 1171734, 103972, 122621 | Factory-matched for Carrier air handler applications
• OEM vs Generic: OEM control boards use factory-programmed timing circuits and relay ratings. Generic aftermarket boards frequently ship with mismatched time delay intervals and lower-rated relays, leading to premature failure and potential blower motor damage. This is the same board that came in your unit from the factory.
• Install Difficulty: 3/5 — Disconnect power and verify 0V at the board before handling. Document all wire harness connections with photos before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Transfer wire connectors one at a time to avoid miswiring. Restore power and confirm blower staging at thermostat before closing the unit.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse. All parts are brand-new genuine Carrier components — never refurbished or pulled from used equipment.
