OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNC042T00AAAA

This is the genuine OEM Carrier fan blower control board (part number HK61EA006), the factory-specified replacement for the Carrier PF1MNC042T00AAAA air handler. The control board serves as the operational hub of the blower system — managing fan speed sequencing, coordinating thermostat signals, and governing the built-in time-delay relay that keeps the blower running after a call for cooling ends. When this board fails, common symptoms include the blower fan refusing to start, running continuously regardless of thermostat input, the system failing to cool, or erratic fan speed behavior. Replacing this board with the correct OEM part restores factory-programmed logic and eliminates guesswork.

• OEM vs Generic: This is a genuine Carrier Factory Authorized Part programmed to exact factory specifications. Generic aftermarket boards may replicate the basic circuit but often lack precise time-delay calibration, increasing the risk of short-cycling, premature motor wear, and voided system warranties.
• Install Difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: 1/4" nut driver, flathead and Phillips screwdrivers, needle-nose pliers, and a phone or camera to photograph all wiring connections before removal. Transfer wiring harnesses one connector at a time to avoid miswiring. Re-check all connections before restoring power.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.
