OEM Carrier Furnace Control Board HK42FZ013 for Model PG8MAA048110ADJA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG8MAA048110ADJA gas furnace. The control board is the brain of your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor through every heating cycle. When it fails, symptoms include a furnace that won't light, repeated lockout fault codes, random short-cycling, or a system that's completely unresponsive despite the thermostat calling for heat. Replacing the board with the factory-specified OEM part restores precise sequencing and eliminates nuisance faults caused by out-of-spec aftermarket timing.

• Specs: Part No. HK42FZ013 | Input: 98–132 VAC at 60 Hz | Igniter Output: 5A at 120 VAC | Cool Blower: 30A, 2 HP, 240 VAC | Heat Blower: 5A, 1/2 HP, 240 VAC | Inducer Motor: 4A at 120 VAC | 24 VAC thermostat compatible | Diagnostic LED fault codes included
• OEM vs Generic: OEM boards carry factory-calibrated ignition trial timing (5-second trial, 3 retries) and 100% gas shutoff on ignition failure. Generic boards may use looser timing tolerances, increasing the risk of nuisance lockouts or unsafe gas events. For a gas appliance, OEM is strongly recommended.
• Install Difficulty: 3/5 — Requires shutting off gas and disconnecting 120V power before beginning. Photograph all wiring harness connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Electrostatic discharge precautions required — touch a grounded metal surface before handling the board.
