OEM Carrier Furnace Control Board HH680001 for Model UPFLOW150U6019A

This is the genuine OEM Carrier circuit board (part number HH680001), the factory-specified replacement for the Carrier UPFLOW150U6019A upflow furnace. The control board is the central command module of your furnace — it sequences the inducer motor, igniter, gas valve, and blower in precise timed cycles. When it fails, you may experience symptoms such as a complete no-heat condition, repeated hard lockouts, erratic blower operation, failure to ignite, or status LED fault codes that cannot be cleared by resetting the thermostat.

• OEM Part Number: HH680001 | Also replaces: 58GA680087, P771-1003, 75598, 58GA75598 | Factory-matched to Carrier UPFLOW150U6019A specifications
• OEM vs Generic: This is a genuine OEM board — not an aftermarket clone. Third-party control boards often lack exact firmware timing, relay ratings, and connector pinouts, leading to misdiagnosis or repeat failures. Always use OEM on control boards.
• Install Difficulty: 4/5 — Requires shutting off 120V power and gas supply before beginning. Tools needed: ¼" and 5/16" nut drivers, needle-nose pliers, smartphone (to photograph all wiring harness connections before disconnecting). Note all diagnostic LED flash codes before removing the old board. Not recommended as a first DIY repair — consult a licensed HVAC technician if uncertain.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
