The Goodman B1370724 is a genuine OEM ignition control module engineered as a direct-fit replacement for the Goodman GUPI075-4 gas furnace. This integrated furnace control board manages the ignition sequence, safety timing, blower delays, and flame verification, coordinating the pressure switch, limit circuits, and gas valve to deliver reliable, code-compliant heating. When your furnace won't light, short-cycles, or trips on safety, a failed ignition module is one of the most common causes.
The genuine OEM B1370724 is programmed with the exact ignition timing, trial-for-ignition, and blower profiles specified for the GUPI series. Generic or aftermarket boards may fit physically but can use different timing curves that cause nuisance lockouts, incorrect blower operation, or premature failure. Choosing OEM guarantees factory-matched performance and preserves your equipment warranty.
Rating: Advanced (4/5). Involves 120V line voltage and low-voltage control wiring. We strongly recommend a licensed HVAC technician. Always disconnect power at the breaker before servicing, and photograph all wire connections before removal so each lead returns to its original terminal.
Every part ships fast and is backed by our 1-year replacement warranty. Questions about fitment? Contact info@nationalhvacparts.com before ordering.
