A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds.

Goodman B1370724 Ignition Control Module

The Goodman B1370724 is a genuine OEM furnace ignition control module for the Goodman/Amana GUX120-5 gas furnace. This board is the brain of the heating sequence — it manages hot surface igniter warm-up, opens the gas valve, verifies flame via the sensor, and enforces safety lockout timing. Symptoms of a failed module include no ignition, a furnace that locks out after ignition attempts, an igniter that glows but no gas flow, or erratic short-cycling.

Specifications

Function: Integrated ignition control / timing sequence
Ignition type: Hot Surface Ignition (HSI)
Input voltage: 24V control circuit
Manages: Igniter, gas valve, flame sensing, safety lockout
Fits: Goodman/Amana GUX120-5 furnace

OEM vs. Generic

The OEM B1370724 guarantees correct ignition timing, trial-for-ignition counts, and safety lockout behavior programmed for this furnace family. Because ignition modules govern gas and flame safety, we strongly recommend OEM here; a matched generic board is offered only when spec-verified equivalent.

Installation Difficulty

Advanced. Involves gas-fired safety controls and precise wiring of the igniter, gas valve, flame sensor, and 24V connections. This repair is best performed by a licensed HVAC technician. Cut all power at the breaker, photograph the wiring before removal, and verify flame signal after startup.

Is this ignition control module compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my Goodman ignition control module?
