What igniter fits my Goodman furnace?

The correct replacement for Goodman model GUX040-3 — B1401003S is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Goodman equipment which lists the model number GUX040-3 — B1401003S.

My furnace will not ignite. What part is bad?

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. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Is this ignitor compatible with Bryant or Payne systems too?

Many Goodman parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

The Goodman B1401003S Spark Ignition Assembly is the genuine OEM electrode assembly that generates the ignition spark and senses flame on the GUX040-3 gas furnace. It mounts at the burner and provides the high-voltage spark that lights the gas, then confirms flame so the control board keeps the gas valve open. A cracked ceramic insulator, eroded electrode, or carbon buildup shows up as no ignition, delayed light-off, or nuisance lockouts.

Specifications

OEM Part Number: B1401003S
Function: Spark ignition & flame-sensing electrode assembly
Compatible Model: Goodman GUX040-3 furnace
Construction: Ceramic-insulated electrode with mounting bracket
Brand: Goodman (genuine OEM)

OEM vs. Generic

Correct electrode gap and positioning relative to the burner are critical for reliable light-off. This genuine Goodman assembly arrives pre-set to factory geometry. Generic electrodes often need manual bending to fit and can misfire or fail flame sensing, leading to repeat lockouts. OEM gives you plug-and-go reliability.

Installation Difficulty

Moderate. Typically one or two mounting screws and a spark-wire connector, but positioning near the burner matters. A handy homeowner can do it; when in doubt use an HVAC technician. Always shut off power and gas first.
