OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNB018000AAAA

This is the genuine OEM Carrier fan blower control board (part# HK61EA006), the factory-specified replacement for the Carrier PF1MNB018000AAAA air handler. 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.

• Specs: 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″
• OEM vs Generic: This is a genuine Factory Authorized Carrier part — not a third-party substitute. OEM boards deliver exact firmware logic, correct relay timing (~90-second post-cycle blower purge), and proper terminal mapping. Aftermarket boards risk timing errors, mismatched speed taps, and voided equipment warranties.
• Install difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage before opening the air handler cabinet. Tools needed: 1/4″ and 5/16″ nut drivers, needle-nose pliers, multimeter. Photograph all wiring harness connections before removal. Label every connector — incorrect reinstallation can damage the new board or the blower motor.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
