What igniter fits my Goodman furnace?

The correct replacement for Goodman model GMN120-5 — B1401012 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 GMN120-5 — B1401012.

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 B1401012 Burner Ignitor is a genuine OEM replacement designed for GMN120-5 series gas furnaces. This hot surface ignitor heats to glowing temperature to light the burners on each call for heat. A furnace that cycles the inducer and opens the gas valve but never fires is almost always signaling a failed ignitor.

Specifications

OEM Part Number: B1401012
Type: Hot Surface Burner Ignitor (HSI)
Element: Silicon Nitride
Compatible Model: Goodman GMN120-5
Equipment: Gas Furnace
Voltage: 120V

OEM vs. Generic

The genuine Goodman OEM ignitor uses a rugged silicon nitride element that resists thermal shock and lasts significantly longer than budget silicon carbide clones. It matches the factory resistance and mounting exactly — no brackets or splice adapters required. OEM means fewer callbacks and a repair that holds.

Installation Difficulty

Easy (2/5). Cut power to the furnace, disconnect the ignitor plug, remove the mounting screw, and swap. Handle by the ceramic base — never touch the element with bare fingers. Allow 15–20 minutes.
