Goodman B1370724 Ignition Control Module

The B1370724 is a genuine OEM ignition control module for the Goodman GUI100-2 gas furnace. This board is the brain of the ignition sequence: it energizes the igniter, opens the gas valve, monitors the flame-sense signal, and locks out the burner if flame is not proven — protecting against unburned gas buildup. Symptoms of a failed module include no ignition, short cycling, intermittent no-heat calls, or a furnace that clicks but never lights.

Specifications

Function: integrated furnace ignition control
Manages: igniter, gas valve, flame sensing, safety lockout
Fits: Goodman GUI100-2 furnace
OEM part number: B1370724

OEM vs. Generic

Ignition modules are tightly matched to the furnace's timing, flame-rectification thresholds, and connector pinout. The OEM B1370724 drops in with the factory wiring harness and preserves the certified ignition sequence. Universal aftermarket controls exist but often require adapter harnesses and re-jumpering, introducing wiring errors on a component that controls live gas. For this repair we strongly recommend OEM.

Installation Difficulty

Moderate. Photograph the wiring first, disconnect power, transfer connectors one at a time to the new board, and confirm a clean ignition cycle on startup. Plan 30–45 minutes. If comfortable with low-voltage furnace wiring this is DIY-friendly; otherwise use a licensed technician.

Frequently Asked Questions

Does this Control Board fit my Goodman GUI100-2 — B1370724?

Yes. This is the factory-specified OEM control board for the Goodman GUI100-2 — 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 control board on my Goodman GUI100-2 — B1370724?

Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.

My HVAC system is completely dead. What could be wrong?

Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.

Is this control board 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 control board?

OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
