The Goodman B1370724 Ignition Control Module is a genuine OEM electronic control that manages the ignition sequence on GDI150-5 furnaces. Acting as the brain of the heating cycle, it sequences the inducer, energizes the igniter, opens the gas valve, and confirms flame through the sensor — shutting down safely if flame is not proven. Symptoms of a failing module include no ignition, short cycling, blinking diagnostic LEDs, or a furnace that ignites then locks out. Replacing a faulty module restores reliable, safe heating.
We recommend the OEM Goodman module for guaranteed compatibility with the furnace's wiring harness, timing, and flame-sense circuitry. A Generic aftermarket control may cost less but requires careful verification of pinout, ignition type (hot-surface vs. spark), and timing before use — a mismatch can cause nuisance lockouts. For a control board of this importance, OEM is the safer investment.
Advanced (4/5). Photograph the wiring, then transfer each connector one at a time to avoid errors. Confirm line voltage, grounding, and flame-sensor microamp draw after installation. Because this part interfaces with the gas valve and safety chain, professional installation is strongly recommended.
