What igniter fits my Goodman furnace?

The correct replacement for Goodman model GMP100-3 Gas Furnace — 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.

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 ignitor 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 B1401012 Burner Ignitor

The B1401012 is a genuine OEM burner ignitor for the Goodman GMP100-3 gas furnace. The ignitor is the first component the control board energizes on a call for heat; it heats up and lights the burner gas. A cracked, aged, or contaminated ignitor is the single most common cause of no-heat and short-cycle lockout faults on this furnace. Installing a fresh OEM ignitor is the fastest way to restore dependable ignition and clear repeated failed-start errors.

Specifications

Part number: B1401012
Type: Burner ignitor for gas ignition system
Compatibility: Goodman GMP100-3 gas furnace
Mounting: Direct OEM bracket and connector fit
Fit: Exact replacement — no adapters required

OEM vs. Generic

The OEM B1401012 matches the exact resistance, mounting bracket, and connector of the GMP100-3 ignition circuit, so it seats at the correct gap to the burner and lights consistently. Universal ignitors require repositioning and can crack or misfire if the gap is wrong. For dependable first-try ignition, the OEM ignitor is the right part.

Installation Difficulty

Easy (2/5). Typically one or two screws and a single plug connector. Handle the ignitor element by the ceramic base only — skin oils shorten its life. About 15–20 minutes. Shut off power and gas before servicing the burner assembly.
