Carrier HK42FZ064 | Integrated Furnace Control Board | 24V | HSI | OEM


The Carrier HK42FZ064 is a genuine Factory Authorized Part™ designed to regulate the ignition sequence and airflow management in residential gas furnaces. This integrated furnace control (IFC) governs the timing for the Hot Surface Ignitor (HSI), gas valve activation, and multi-speed blower operation. Engineered for the Carrier 58MVP and Bryant 355MAV series, this OEM board ensures the system follows factory-calibrated logic. By continuously polling the system’s limit switches and pressure sensors, it maintains the operational sequence required by the original equipment manufacturer.


Key Features

  • OEM Part # HK42FZ064: A factory-certified replacement that maintains the original UL equipment listing and electrical specifications for Carrier-family furnaces.
  • System Logic Restoration: Specifically engineered to resolve "No Ignition" codes or constant blower run cycles caused by failed legacy circuit boards.
  • Safety Switch Monitoring: Actively monitors the flame sensor and high-limit manual reset switches to interrupt the gas valve if an interruption is detected.
  • Heavy-Duty Relay Design: Features upgraded onboard relays to resolve intermittent inducer motor failures and sticking mechanical contacts.
  • Diagnostic LED Interface: Includes a high-visibility status light that displays specific flash codes, allowing for rapid identification of pressure switch or limit circuit faults.

🛠️ HVAC Depot Pro Tip

Take a Picture First: Before disconnecting the multi-pin molex connectors or individual spade terminals (EAC, HUM, Stat), photograph the original board's wiring. Verify Your Grounding: These OEM boards rely on a micro-amp flame rectification signal; ensure the furnace chassis ground is clean and secure. A poor ground connection can cause a new board to "lock out" even if the flame sensor and ignitor are functioning correctly.
