OEM Carrier Fan Blower Control Board HK61EA006 for Model PF1MNC036000AAAA

This OEM fan blower control board (part number HK61EA006) is the factory-specified replacement for the Carrier PF1MNC036000AAAA air handler. The integrated fan control (IFC) board serves as the central command center for your blower system — managing blower motor speeds, sequencing heating and cooling operation, monitoring safety inputs, and communicating fault codes. When this board fails, symptoms typically include the blower fan not running, the system entering lockout mode, erratic multi-speed fan behavior, or a complete loss of heating and cooling response even when the thermostat is calling.

• Specs: OEM part number HK61EA006 | Factory-matched for Carrier PF1MNC036000AAAA air handlers | 120V/240V input | 24V control circuit output | Integrated LED fault-code diagnostics
• OEM vs Generic: This is an OEM factory board — not an aftermarket substitute. OEM boards carry factory-programmed motor speed profiles and safety timing sequences. Generic boards often ship with mismatched blower delay timing, risking heat exchanger overheating and premature failure.
• Install difficulty: 3/5 — Disconnect power at the breaker before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, a permanent marker to label connectors, and a phone or camera to photograph all wiring harnesses before removal. Note LED fault codes prior to swapping the board for diagnostic reference.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PF1MNC036000AAAA air handler. Always verify your existing board's part number on the board label before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy — no guesswork required.
