OEM Carrier Integrated Furnace Control Board HK42FZ016 for Model PG8UAA060135AAJA

This is the factory OEM integrated furnace control board (IFC) for the Carrier PG8UAA060135AAJA gas furnace, sold under OEM part numbers HK42FZ016 and its direct successor kit 325878-751. The IFC board is the central brain of the furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor on every heat call. When it fails, symptoms range from complete no-heat lockout and repeated ignition attempts, to erratic blower behavior or a furnace that refuses to fire at all. A flashing diagnostic LED on the board itself will flash fault codes to help confirm the board as the root cause before ordering.

• Specs: 24 VAC control circuit | Input range 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, FLA-8.0 LRA at 120 VAC | Microprocessor-based with onboard diagnostic LED fault codes
• OEM vs Generic: The OEM board ships with factory-programmed timing sequences and 100% gas shutoff on ignition failure — critical safety logic that generic aftermarket ICM282-series boards attempt to replicate but may differ in blower-off delay timing, potentially reducing heat exchanger life and comfort.
• Install difficulty: 3/5 — Label and photograph all wire harness connections before removal. Discharge any static before handling. Note: the 325878-751 kit variant ships with adapter harnesses for older wiring configurations. Tools needed: 1/4" nut driver, flathead screwdriver, multimeter, phone/camera for wiring documentation.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our NationalHVACParts.com warehouse.
