OEM Carrier Furnace Control Board HH680001 for Model UPFLOW080U36W19

The Carrier HH680001 circuit board is the factory-specified integrated furnace control (IFC) replacement for the UPFLOW080U36W19 upflow gas furnace. This board serves as the central command hub of your heating system — sequencing ignition, managing inducer and blower motor operation, monitoring safety limits, and processing thermostat signals. When the control board fails, symptoms typically include hard lockouts with no ignition attempt, erratic or intermittent heating cycles, unresponsive thermostat calls, or fault codes that cannot be cleared by resetting the system.

• Part Specs: OEM Carrier part number HH680001 | Also supersedes P771-1003, 58GA680087, 58GA75598, and 75598 | Factory-matched for UPFLOW080U36W19 80% AFUE upflow furnace configuration
• OEM vs Generic: This is a genuine OEM Carrier board — not an aftermarket substitute. OEM boards carry pre-programmed timing sequences, proprietary diagnostic fault codes, and exact connector configurations matched to your furnace wiring harness. Generic boards may require field modifications and often void remaining equipment warranties.
• Install Difficulty: 4/5 — Control board replacement requires shutting off gas supply and 120V power, photographing all wire terminal connections before removal, and careful ESD (electrostatic discharge) handling. Tools needed: flat-head and Phillips screwdrivers, needle-nose pliers, phone/camera for wiring documentation, and a multimeter for pre/post verification. Professional installation strongly recommended for this part category.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff. Cross-references: P771-1003 | 58GA680087 | 58GA75598 | 75598.
