OEM Carrier Circuit Control Board HH680001 for Model UPFLOW150U6019

This is the genuine OEM Carrier circuit board (part number HH680001), the factory-specified replacement for the Carrier UPFLOW150U6019 upflow gas furnace. The integrated furnace control (IFC) board is the central command hub of your heating system — it sequences the inducer motor, igniter, gas valve, blower motor, and all safety switches in precise coordination. When this board fails, symptoms typically include a furnace that won't ignite, a system stuck in lockout, erratic blower behavior, or fault codes flashing on the LED diagnostic indicator with no corresponding resolution.

• OEM Part Number: HH680001 | Also supersedes: 58GA680087, P771-1003, 75598, 58GA75598 — Factory-matched for exact fit and full functionality on UPFLOW150U6019
• OEM vs Generic: This is a genuine Carrier OEM board, not a third-party substitute. Aftermarket boards frequently omit proprietary fault-code logic and may not honor all safety lockout sequences, creating liability and call-back risk. OEM ensures every relay timing, terminal assignment, and diagnostic routine matches factory spec precisely.
• Install Difficulty: 4/5 — Control board replacement requires shutting off 120V power and gas supply, photographing or labeling all terminal connections before removal, and carefully transferring wiring harnesses to the new board. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone/camera for wiring documentation. Recommend a licensed HVAC technician for this repair.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed as the direct OEM replacement for the Carrier UPFLOW150U6019 upflow gas furnace.
