OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANC036005AGAA

This is the genuine OEM fan blower control board (part number HK61EA002) factory-specified for the Carrier FA4ANC036005AGAA air handler. The blower control board is the central intelligence of your air handler — it sequences blower motor operation, manages fan speed staging, interprets thermostat signals, and coordinates heating and cooling cycles. When this board fails, symptoms typically include the blower motor refusing to start, running continuously regardless of thermostat commands, erratic fan speeds, or a complete system lockout with no airborne airflow across the coil.

• Specs: OEM Part Number HK61EA002 | 24V control circuit input | Multi-speed blower motor control | Compatible with single-stage cooling configuration | Replaces factory board with exact terminal layout and logic firmware
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards carry factory-programmed timing delays, fault detection logic, and terminal configurations that generic boards frequently get wrong, leading to nuisance lockouts, improper fan ramp-up, or voided equipment warranties.
• Install difficulty: 3/5 — Disconnect power at the breaker before starting. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, phone or camera to photograph all wiring harness connections before removal. Label every wire. Board swap is straightforward but wiring must be exact — incorrect termination can damage the new board immediately upon power restoration.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse for orders placed before cutoff.

Compatibility: Engineered as the direct factory replacement for the Carrier FA4ANC036005AGAA air handler (3-ton, single-stage). Confirm part number HK61EA002 on your existing board's label before ordering.
