OEM Carrier Fan Blower Control Board HK61EA006 for Model PF4MNA060000AAAA

This is the factory OEM fan blower control board for the Carrier PF4MNA060000AAAA air handler. The HK61EA006 is the central command hub of your air handler's blower operation — it governs fan speed sequencing, time-delay relay logic, and communicates with your thermostat to coordinate cooling and heating cycles. When this board fails, common symptoms include the blower running continuously even with the thermostat off, the fan refusing to start, indoor coils freezing over due to improper airflow staging, or the system entering a no-response lockout condition.

• Specs: OEM Part No. HK61EA006 | Cross-references: CEPL130541-01, 1171734, 103972, 122621 | Integrated time-delay relay | Diagnostic LED fault indicators | Compact form factor: 4.1"W × 4.2"D × 2.1"H | 24V control circuit compatible
• OEM vs Generic: This is the genuine Carrier factory board — not an aftermarket clone. OEM boards are pre-programmed with exact time-delay sequences and relay logic matched to your system. Generic boards frequently use mismatched relay timing, which can cause short-cycling, blower over-run, or nuisance lockouts that a generic board cannot self-diagnose.
• Install difficulty: 3/5 — Disconnect power at the breaker before opening the air handler cabinet. Photograph all wiring harness connections before removal. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Take note of any active fault LED codes on the old board before powering down — they can confirm the diagnosis. Re-seat all connectors firmly and verify 24V signal at the board after restoration.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.
