What igniter fits my Goodman furnace?

The correct replacement for Goodman model GSM100-4 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 GSM100-4 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 igniter for GSM100-4 gas furnaces and compatible Goodman/Amana models. When the thermostat calls for heat, the control board energizes this igniter until it glows red-hot, lighting the main burners. It is one of the most common wear items in any hot-surface-ignition furnace.

A cracked or failed ignitor is the leading cause of no-heat calls: the inducer runs, but the burners never light and the furnace locks out. This durable silicon-nitride-style element resists thermal shock and delivers fast, consistent light-off cycle after cycle.

Part type: Hot surface ignitor (HSI)
Element: Silicon nitride, high thermal-shock resistance
Voltage: 120 VAC
Fits: Goodman GSM100-4 and compatible Goodman & Amana furnaces
OEM Part #: B1401018S (includes mounting bracket & connector)

OEM vs. Generic: The OEM B1401018S arrives with the correct bracket and plug so it drops straight in with no rewiring. Universal ignitor kits can work but require adapting the harness and bending the bracket, and cheaper carbide elements are more brittle. For fastest, most reliable installation choose OEM.

Install difficulty: Easy (2/5). Shut off power, unplug the igniter connector, remove one or two mounting screws, and reverse to install. Handle the fragile element by the ceramic base only — never touch the glowing tip. About 15 minutes.
