What igniter fits my Goodman furnace?

The correct replacement for Goodman model WFM18090S4BXCB — 20165703S 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 WFM18090S4BXCB — 20165703S.

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 20165703S Hot Surface Ignitor is a genuine OEM ignition component engineered for the Goodman/Amana WFM18090S4BXCB gas furnace and compatible models. When your furnace clicks but fails to light, a cracked or worn ignitor is the most common cause. This factory-spec part restores reliable, on-demand ignition and eliminates the no-heat call.

Built to Goodman's exact resistance and dimensional specifications, the 20165703S drops into the original mounting bracket with no modification. The silicon nitride element heats to ignition temperature in seconds and resists the thermal cycling and micro-cracking that shortens the life of cheaper universal igniters.

Specifications

OEM Part Number: 20165703S
Type: Hot surface ignitor (silicon nitride)
Fits: Goodman/Amana WFM18090S4BXCB and compatible furnaces
Voltage: 120V ignition circuit
Direct OEM-fit mounting bracket and connector

OEM vs. Generic

Generic hot surface ignitors often use brittle silicon carbide elements and loose-tolerance brackets that force you to re-bend tabs or splice connectors. This genuine OEM 20165703S guarantees correct resistance, plug-and-play wiring, and the durability Goodman certifies — meaning fewer repeat failures and a longer service interval.

Install Difficulty

Easy (1 of 5). Cut power, remove the burner-compartment access panel, unplug the connector, remove one or two mounting screws, and swap. Handle the fragile ceramic element by the base only — never touch the igniter tip. Typical replacement time is 10–15 minutes.
