OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANF036008AFAA

This OEM fan blower control board (part number HK61EA002) is the factory-specified replacement for the Carrier FA4ANF036008AFAA air handler unit. The integrated fan control board serves as the command center of your air handler — managing blower motor speeds, sequencing heating and cooling operation, interpreting thermostat signals, and protecting the system through built-in fault detection. When this board fails, symptoms typically include the blower fan not running, the system failing to respond to thermostat calls, erratic cycling, or a continuously illuminated fault code LED indicating a control board lockout. Replacing it with a genuine OEM board ensures every relay, timing circuit, and speed tap is calibrated exactly to factory specifications.

• Specs: OEM part number HK61EA002 | Factory fan blower control board | Compatible with 3-ton (036) air handler configuration | Multi-speed blower control with integrated fault diagnostics
• OEM vs Generic: This is a genuine Carrier OEM board, not an aftermarket substitute. Generic control boards often feature mismatched relay ratings and imprecise timing sequences that can cause nuisance lockouts, improper airflow staging, or premature component failure across connected equipment.
• Install Difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph all wire harness connections prior to removal. Label each connector before disconnecting. A multimeter is recommended to verify 24V control circuit continuity post-install.
• Warranty: 1-year OEM factory warranty against defects. In-stock units ship same business day when ordered before cutoff.

Compatibility: Designed and factory-matched for the Carrier FA4ANF036008AFAA air handler.
