OEM Carrier Fan Blower Control Board HK61EA006 for Model PF4MNA048L00AAAA

This is the OEM factory-authorized fan blower control board for the Carrier PF4MNA048L00AAAA air handler. Part number HK61EA006 is the nerve center of your blower system — it manages fan speed sequencing, the integrated time delay relay, and all low-voltage control signals between the thermostat and the air handler. When this board fails, common symptoms include the blower fan refusing to start, the fan running continuously regardless of thermostat demand, erratic speed behavior, or the entire air handler going into a fault/lockout condition. Replacing this board with the genuine OEM part restores factory-programmed timing and sequencing logic that aftermarket boards often cannot replicate precisely.

• Part Number & Specs: Carrier OEM HK61EA006 | Replaces cross-references CEPL130541-01, 1171734, 103972, 122621, CEBD430541-03A | Integrated time delay relay | Factory-matched control logic for 4-ton air handler platform
• OEM vs Generic: OEM boards are programmed with exact Carrier timing parameters and are tested to factory tolerances. Generic or third-party boards may use approximate relay timing, leading to short-cycling, compressor stress, or repeat board failures within one to two seasons.
• Install Difficulty: 3/5 — Requires safe lockout/tagout of 240V power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone camera to photograph all wiring connections prior to removal. Label each wire before disconnecting. Incorrect wiring can immediately damage the new board.
