OEM Carrier Fan Blower Control Board HK61EA010 for Model FX4CNB048000AAAA

This is the genuine OEM fan blower control board (part number HK61EA010), factory-specified for the Carrier FX4CNB048000AAAA air handler unit. The control board serves as the command center for your air handler's blower operation — it processes signals from the thermostat, manages blower motor speed sequencing, and coordinates cooling, heating, and continuous fan modes. When this board fails, symptoms typically include the blower fan not starting at all, the fan running continuously regardless of thermostat commands, erratic multi-speed operation, or a complete system lockout with no response to any thermostat input.

• Specs: OEM Part Number HK61EA010 | Designed for Carrier FX4CNB048000AAAA air handler | 24V control circuit interface | Multi-speed blower motor control | Factory-matched logic and terminal layout
• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards carry the exact firmware logic, relay ratings, and terminal configurations engineered for your unit. Generic control boards frequently cause nuisance lockouts, incorrect blower speed staging, and may void remaining equipment warranties.
• Install Difficulty: 3/5 — Control board replacement requires working safely around 120V and 240V wiring inside the air handler cabinet. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and phone or camera for photographing all wiring connections prior to removal. Always disconnect power at the breaker and confirm voltage is absent before touching any terminals. If uncomfortable working with line voltage, consult a licensed HVAC technician.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse when ordered before 3PM local time.

Compatibility: This board is engineered specifically for the Carrier FX4CNB048000AAAA 4-ton residential air handler. Always cross-reference OEM part number HK61EA010 against your unit's data plate and existing board labeling before ordering. Need fitment confirmation?
