What igniter fits my Goodman furnace?

The correct replacement for Goodman model GUS100-4 Furnace — B1401018S 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 GUS100-4 Furnace — B1401018S.

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 igniter 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 B1401018S Hot Surface Ignitor is the genuine OEM silicon-carbide igniter for the GUS100-4 gas furnace. On each call for heat the control board energizes this element until it glows white-hot, lighting the burners. HSIs are brittle and wear out from repeated thermal cycling — cracking or reading open-circuit — which leaves the furnace with a healthy inducer and gas valve but no flame. This exact-fit replacement restores dependable first-try ignition.

Part Number: B1401018S
Type: Hot surface ignitor (silicon carbide)
Fits: Goodman GUS100-4 gas furnace
Voltage: 120V HSI
Function: Ignites burners on each heat cycle

OEM vs. Generic

This genuine Goodman ignitor comes with the correct bracket, gasket, and plug so it seats at the exact height and angle in the burner flame path. Universal HSI kits require adapting the mount and can sit too high or low, causing slow or failed ignition and premature failure. Given how ignition-critical and fragile this component is, the OEM part is the dependable choice.

Installation Difficulty

Easy (2/5). Cut power, remove one or two mounting screws, unplug the connector, and install the new ignitor. Never touch the ceramic element with bare fingers — skin oils create hot spots that cause early failure. Handle by the bracket only. About 20 minutes.
