OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNB018008AAAA

This is the genuine OEM Carrier fan blower control board (part number HK61EA006), factory-specified for the Carrier PF1MNB018008AAAA air handler. The blower control board serves as the command center for the indoor blower motor, managing fan speed sequencing, time-delay relay operation, and communication between the thermostat signal and the air handler's blower assembly. When this board fails, common symptoms include the blower fan refusing to start, the fan running continuously regardless of thermostat commands, erratic multi-speed blower behavior, or the entire air handler going into lockout mode with no airflow to the living space.

• Specs: Carrier OEM Part # HK61EA006 | Integrated time-delay relay | Compatible board references: CEPL130541-01, CEBD430541-03A | Cross-references: 1171734, 103972, 122621
• OEM vs Generic: This OEM board is factory-matched to Carrier's exact firmware and relay timing sequences. Aftermarket boards often use off-spec time-delay relays that cause premature blower shutoff, short-cycling, or nuisance lockouts — shortening motor life and voiding system warranties.
• Install Difficulty: 3/5 — Shut off power at the breaker and disconnect the service panel before beginning. Photograph or label all wire harness connectors before removal. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, and a multimeter to confirm 24V control power before reinstalling the panel. Take note of any DIP switch settings on the old board and replicate them on the new one.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered before 3 PM local time.
