OEM Carrier Fan Blower Control Board HK61EA002 for Model FA4ANC048008AFAA

This is the genuine OEM fan blower control board (part number HK61EA002), factory-specified for the Carrier FA4ANC048008AFAA air handler. The fan blower control board is the nerve center of your air handler — it manages blower motor speed sequencing, cooling and heating operation modes, and communicates with the thermostat and outdoor unit. When this board fails, symptoms typically include the blower fan not starting, erratic or continuous blower operation, incorrect fan speed staging, or a complete system lockout with no response to thermostat calls.

• Specs: OEM Part Number HK61EA002 | Designed for multi-speed PSC or ECM blower motor control | 24V control circuit input | Factory-programmed timing and speed profiles matched to the FA4ANC048008AFAA air handler platform
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. Generic control boards frequently ship with mismatched firmware, incorrect blower delay timing, and incompatible terminal layouts, resulting in callbacks and repeat failures. The OEM board installs correctly the first time with zero reprogramming required.
• Install Difficulty: 3/5 — Disconnect power at the breaker and verify zero voltage before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a phone or camera to photograph all wiring harness connections prior to removal. Take care handling the board to avoid static discharge. Most experienced DIYers and technicians complete this swap in 30–60 minutes.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our climate-controlled parts warehouse.

Compatibility: Engineered specifically for the Carrier FA4ANC048008AFAA 4-ton residential air handler.
