OEM Carrier Furnace Control Board HK42FZ013 for Model PG9MAB036060AASA

This OEM integrated furnace control (IFC) board is the factory-specified replacement for the Carrier PG9MAB036060AASA gas furnace. The control board serves as the central brain of your furnace — orchestrating the ignition sequence, monitoring flame sensor signal, managing inducer and blower motor staging, and protecting the system through built-in diagnostic fault codes. When it fails, symptoms include complete no-heat lockout, erratic ignition attempts, blower running continuously, or a blank/flashing LED fault display with no call for heat.

• Specs: OEM Part Number HK42FZ013 | 24V control circuit | Integrated diagnostic LED fault code display | Compatible with single-stage gas valve and hot surface igniter configuration | Factory-matched for Carrier PG9MAB036060AASA
• OEM vs Generic: This is a genuine OEM Carrier control board built to exact factory specifications. Aftermarket boards often lack full fault code compatibility and precise timing sequences, risking nuisance lockouts, improper ignition staging, and voided equipment warranties.
• Install Difficulty: 4/5 — Control board replacement requires shutting off power and gas supply before starting. Carefully document or photograph all wiring harness connections prior to removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone/camera for wiring photos. If LED fault codes are unreadable, consult the service manual before pulling the board. Recommended for experienced DIYers or licensed HVAC technicians.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
