OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNB036008AAAA

This OEM fan blower control board is the factory-specified replacement for the Carrier PF1MNB036008AAAA air handler. The integrated fan control (IFC) board orchestrates every stage of system operation — managing blower motor speeds, sequencing heating and cooling calls from the thermostat, monitoring safety inputs, and executing timed off-delays that protect the heat exchanger and evaporator coil. When this board fails, common symptoms include the blower failing to run on any speed, the system locking out with fault codes, erratic fan cycling, or a complete loss of heating and cooling response despite correct thermostat signals.

• Specs: OEM Part Number HK61EA006 | Factory fan blower control board | Multi-speed blower motor control | 24V control circuit input | Integrated fault code diagnostic LED
• OEM vs Generic: This is a factory-original Carrier board — firmware, relay ratings, and terminal layouts are an exact match for the PF1MNB036008AAAA. Aftermarket boards often require wiring modifications, may omit diagnostic LED logic, and carry higher early-failure rates that void system warranties.
• Install difficulty: 3/5 — Requires shutting off power at the breaker and air handler disconnect. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter, camera or phone to photograph all wiring before disconnection. Carefully transfer one wire at a time to the new board to prevent miswiring. Consult the unit's wiring diagram located inside the cabinet door.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
