The Goodman B1370724 Ignition Control Module is a genuine OEM replacement for GDX120-5 furnaces. This board manages the ignition sequence — governing the igniter, gas valve timing, flame sensing, and safety lockout. When a furnace won't light, short-cycles, or locks out on ignition faults, a failed control module is a common culprit. Restoring the correct module brings back safe, reliable startups.

OEM vs. Generic

Control electronics are safety-critical. The OEM Goodman B1370724 is programmed with the exact ignition timing and safety logic your furnace requires. Generic or salvaged boards risk mismatched timing, nuisance lockouts, or unsafe operation. For a control module, OEM is strongly recommended.

Installation Difficulty

Advanced. Requires mapping and transferring wiring harnesses exactly, verifying line voltage, and testing the ignition sequence. Best performed by a licensed HVAC technician. Always shut off power and gas before servicing.

Confirm your furnace is a GDX120-5 before ordering this control module.

Frequently Asked Questions

Does this Ignition Module fit my Goodman GDX120-5 — B1370724?
Yes. This is the factory-specified OEM ignition module for the Goodman GDX120-5 — B1370724. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the ignition module on my Goodman GDX120-5 — B1370724?
Difficulty: Medium (20–30 min)
Step 1: Turn off power and gas. Step 2: Open furnace panel. Step 3: Locate igniter near burners. Step 4: Disconnect two-wire plug. Step 5: Remove mounting screw. Step 6: Install new igniter — do NOT touch element with fingers. Step 7: Reconnect, close panel, restore power/gas.
My furnace won’t ignite. What part is bad?
Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.
Is this ignition module compatible with Bryant or Payne too?
Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Goodman ignition module?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
