OEM Carrier Fan Blower Control Board HK61EA002 for Model FB4ASX024000AEAA

This is the factory OEM fan blower control board (part number HK61EA002) for the Carrier FB4ASX024000AEAA air handler. The control board serves as the central command module for the blower assembly, orchestrating fan speed sequencing, heating and cooling relay switching, and communicating with the thermostat to deliver proper airflow at each stage of operation. When this board fails, you may experience a blower that won't start, runs continuously regardless of thermostat calls, operates at the wrong speed, or causes the entire system to go into lockout mode. Replacing it with a factory-matched OEM board ensures every relay, timing circuit, and terminal connection aligns precisely with the original design specifications of your unit.

• Specs: OEM part number HK61EA002 | Designed for Carrier FB4ASX024000AEAA air handler | 24V control circuit compatible | Factory-wired terminal layout matches original board exactly
• OEM vs Generic: OEM control boards carry exact firmware logic and relay ratings engineered for your specific model. Aftermarket boards often use generalized timing sequences and lower-grade relays that can cause nuisance lockouts, improper fan speeds, or premature failure — costing more in callbacks and labor than the price difference saves.
• Install Difficulty: 3/5 — Requires shutting off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, smartphone camera (to photograph all wire connections before removal). Carefully transfer wires one at a time to avoid miswiring. Verify system operation through a full heating and cooling cycle after installation.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.
