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.

Specifications

OEM Part Number: 20165703S
Category: Hot Surface Ignitor (HSI)
Brand: Goodman (OEM)
Fits Model: WFD18090S4BXCB gas furnace
Element: Durable high-temperature ignitor element
Fit: Direct OEM replacement with matching mounting and connector

OEM vs. Generic

This OEM Goodman ignitor matches the factory resistance, mounting bracket, and plug so it seats and sequences correctly with the furnace control board. Universal ignitors often require adapter harnesses and may not match the glow profile, leading to hard starts. For plug-and-play reliability, choose OEM.

Installation Difficulty

Easy (2/5). Usually one or two screws and a single wire connector — about 15–30 minutes. Handle the fragile element by the base only; skin oils shorten its life. Cut power before servicing, and hire a licensed HVAC pro if you're unsure.
