This board is the brain of the ignition sequence — it powers the igniter, opens the gas valve, monitors the flame-sense signal, and locks out safely if ignition fails. Symptoms of a failed module include no ignition, short-cycling, a furnace that clicks but won't light, or repeated lockouts even after the igniter and flame sensor test good.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Ignition control \/ flame supervision module\u003c\/li\u003e\n\u003cli\u003eManages: Igniter, gas valve, flame sensing, safety lockout\u003c\/li\u003e\n\u003cli\u003eCompatible model: Goodman GUI100-3 furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370724\u003c\/li\u003e\n\u003cli\u003eFactory-matched connector pinout and timing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM module\u003c\/strong\u003e carries the exact ignition timing, trial-for-ignition period, and flame-sense thresholds this furnace was engineered around, with a plug-and-play harness connector.
