What igniter fits my Goodman furnace?

The correct replacement for Goodman model GMP100-4 Furnace — 20261709S is this exact part. It is the factory-specified replacement with exact OEM specifications.

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.

The Goodman 20261709S Hot Surface Ignitor is a genuine OEM ignition component for the Goodman GMP100-4 gas furnace. A failed or cracked hot surface ignitor (HSI) is the single most common cause of no-heat calls — this OEM replacement restores fast, reliable burner ignition and returns your furnace to dependable service.

Specifications

Part Type: Hot surface ignitor (HSI)
Function: Electrically heated ignition element for gas burners
Fit: Goodman GMP100-4 and compatible furnace models
OEM Part Number: 20261709S
Brand: Goodman (genuine OEM)

OEM vs. Generic

The genuine OEM ignitor uses Goodman's factory element material and mounting bracket, delivering the correct resistance and glow temperature for consistent light-off. Universal aftermarket ignitors often require bracket adapters and may have shorter service life. When reliable heat matters, OEM is the recommended path.

Installation Difficulty

Moderate (2 of 5). Disconnect power, remove the single mounting screw and the two-pin connector, and replace — handle the fragile ignitor element by the ceramic base only, never the hot surface. A DIY-capable homeowner can complete this in about 15 minutes.

Confirm OEM number 20261709S matches your existing ignitor before ordering to ensure correct fit on your GMP100-4.
