OEM Carrier Circuit Control Board HH680001 for Model UPFLOW200U6020A

This is the genuine OEM Carrier circuit board (part number HH680001), factory-specified for the Carrier UPFLOW200U6020A upflow gas furnace. The control board is the central command module of your furnace — it orchestrates ignition sequencing, inducer and blower motor timing, pressure switch verification, flame sensing, and fault code diagnostics. When this board fails, symptoms typically include complete no-heat lockout, erratic cycling, unresponsive thermostat calls, or persistent fault codes that cannot be cleared by a reset alone.

• OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket substitute. OEM boards include factory-programmed timing sequences, diagnostic LED logic, and exact connector layouts.
