What igniter fits my Goodman furnace?

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.

Goodman B1401018S Hot Surface Ignitor

The Goodman B1401018S is a genuine OEM hot surface ignitor (HSI) engineered for the Goodman GMT115-5A gas furnace. The ignitor heats to a glowing temperature to light the main burners on each call for heat. A cracked or worn ignitor is the single most common cause of intermittent or complete no-heat furnace failures.

Specifications

Part Number: B1401018S
Type: Hot Surface Ignitor (HSI)
Function: Burner ignition on heat call
Equipment: Gas furnace
Compatible Model: GMT115-5A
Brand: Goodman (OEM)

OEM vs. Generic

The genuine OEM Goodman ignitor arrives with the correct mounting bracket, connector, and resistance rating for your control board's ignition sequence. Universal ignitor kits require adapting the mount and harness and can misread on the flame sequence. The OEM part drops in without modification.

Installation Difficulty

Easy (2/5). Shut off power and gas, remove the burner access panel, unplug the ignitor connector, remove the mounting screw, and install the new unit. Handle the ceramic element by the base only — skin oils shorten its life. Roughly a 15–20 minute job.

Turn off power and gas before servicing. If unsure, consult a licensed HVAC professional.
