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 B1370724 is a genuine OEM Goodman ignition control module built for the GUX100-5 gas furnace. This is the brain of the ignition sequence — it energizes the igniter, opens the gas valve, monitors the flame-sense signal, and enforces safety timings and lockouts. Symptoms of a failed module include no ignition, short cycling, an igniter that glows but no gas, or repeated safety lockouts. Replacing the module restores reliable, code-compliant furnace startup.

Specifications

Component: Integrated furnace ignition control module
OEM Part Number: B1370724
Fits: Goodman GUX100-5 furnace platform
Functions: Igniter control, gas-valve sequencing, flame sensing, safety lockout
Control voltage: 24VAC with line-voltage switching

OEM vs. Generic

Ignition modules carry brand-specific timing, terminal pinouts, and flame-sense thresholds. The genuine OEM B1370724 matches the furnace harness and ignition sequence exactly, ensuring correct trial-for-ignition and lockout behavior. Aftermarket or "universal" boards often require adapter harnesses and reprogramming of timings — risky on a safety-critical control. We strongly recommend OEM.

Install Difficulty

Moderate (3/5). Roughly 45–60 minutes. Cut power, photograph and label every connection, transfer the harness plug and spade terminals to the matching positions on the new module, and remount. A multimeter and comfort with furnace control wiring are needed. Given the safety-critical role, a licensed HVAC technician is recommended if you are not experienced with ignition controls.

Always disconnect power before servicing. Verify flame-sense microamps after replacement.

My furnace won’t ignite. What part is bad?

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

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