The Goodman B1370724 is a genuine OEM furnace ignition control module built as a direct-fit replacement for the Goodman GUI075-2 gas furnace. This board is the brain of the ignition sequence — it manages the igniter warm-up, opens the gas valve, verifies flame via the flame-sensing circuit, and controls blower timing. Symptoms of a failed module include no ignition, short cycling, lockout after a few tries, or the furnace failing to light despite a good igniter and sensor.
Ignition control boards are safety-critical and model-specific. Genuine Goodman modules are pre-programmed with the exact timing and lockout parameters your furnace was engineered for. Universal or generic boards often require jumper reconfiguration and may not replicate factory safety timings, risking nuisance faults or unsafe operation. The OEM B1370724 plugs into the existing connectors for a true drop-in fit.
Moderate. Power must be shut off at the breaker. Photograph and transfer each wiring connector one at a time to avoid errors. No programming required. Allow 30–45 minutes. If you're unsure about flame-sensing wiring, use a qualified technician.
