What igniter fits my Goodman furnace?

The correct replacement for Goodman model GMP125-5 — 20261709S 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 GMP125-5 — 20261709S.

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.

Genuine Goodman 20261709S Hot Surface Ignitor

The Goodman 20261709S is an OEM 120-volt hot surface ignitor (HSI) built for the Goodman GMP125-5 gas furnace and compatible Goodman/Amana models. When the thermostat calls for heat, the control board energizes the ignitor, which glows to light the burner assembly. A cracked or worn ignitor is the single most common cause of no-heat and short-cycling faults, making this a first-line replacement part.

Specifications

OEM Part Number: 20261709S
Type: Hot surface ignitor (HSI)
Voltage: 120V
Element: Silicon carbide, factory-mounted bracket
Compatible Model: Goodman GMP125-5 (and select Goodman/Amana furnaces)

OEM vs. Generic

The OEM 20261709S ships with the correct bracket, gasket, and connector already mounted, so it drops into the exact factory position with the proper burner gap. Universal ignitor kits require you to transfer hardware and hand-set clearance — get it wrong and you risk delayed ignition, roll-out, or premature element failure. OEM eliminates the guesswork.

Install Difficulty

Moderate (2/5) — Requires removing the burner-compartment door and unplugging the ignitor harness. Handle the fragile element by the ceramic base only; skin oils and impacts cause hairline cracks. Budget 15–30 minutes.

Always shut off power and gas before servicing. If unsure, contact a licensed HVAC technician.
