OEM Carrier Fan Blower Control Board HK61EA006 for Model FA4BNF036000AAAA

This OEM fan blower control board (part number HK61EA006) is the factory-specified replacement for the Carrier FA4BNF036000AAAA air handler. The blower control board serves as the central command module for the air handler's indoor blower motor — regulating fan speeds, coordinating with the thermostat signal, managing heat/cool delays, and sequencing low-voltage control circuit functions. When this board fails, symptoms typically include the blower motor not running at all, the system running continuously without shutting off, erratic or incorrect fan speeds, or diagnostic fault codes flashing on the board itself. In some cases, a failed control board will cause the entire air handler to become non-responsive even when the thermostat is calling for heating or cooling.

• Specs: OEM Part Number HK61EA006 | 24V low-voltage control circuit | Multi-speed blower motor control | Integrated diagnostics with LED fault codes | Factory-calibrated timing delays for safe operation
• OEM vs Generic: This is a genuine Carrier OEM board, not an aftermarket substitute. Generic control boards often ship without pre-configured fan delay settings and may lack the exact terminal layout or firmware logic required for the FA4BNF036000AAAA, risking improper operation or compressor damage.
• Install Difficulty: 3/5 — Requires shutting off all power at the breaker and air handler disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, smartphone or camera to photograph all wiring connections before removal. Transfer low-voltage wiring terminal by terminal to avoid miswiring. Allow 5 minutes after power-off before touching board terminals.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our stocked warehouse — no back-order delays.
