What igniter fits my Goodman furnace?

The correct replacement for Goodman model GUE120-5 Furnace — 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 GUE120-5 Furnace — 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 ignition 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.

Goodman B1401003S Spark Ignition Assembly

The B1401003S is a genuine Goodman spark ignition assembly built for GUE120-5 gas furnaces. This assembly generates the high-voltage spark that lights the pilot or main burner on each heating call. Over time the electrode gap widens, the ceramic insulator cracks, or the spark rod corrodes — resulting in delayed ignition, repeated lockouts, or a furnace that won't fire at all. Installing a fresh OEM ignition assembly restores fast, dependable light-off and eliminates nuisance no-heat calls.

OEM Part Number: B1401003S
Part Type: Spark Ignition Assembly / Ignitor Electrode
Brand: Goodman

OEM vs. Generic

The genuine Goodman assembly arrives with the correct electrode gap, mounting bracket, and lead length pre-set for the GUE120-5 burner. Generic ignitors often require re-gapping and may not seat correctly against the burner, risking misfire. The OEM part is a tested, drop-in replacement that meets Goodman's ignition timing specs.

Installation Difficulty

Moderate (3/5) — Involves working near the gas burner and high-voltage ignition wiring. Shut off gas and power first. Recommended for experienced DIYers or a licensed HVAC technician. Typical replacement time is 30–45 minutes.
