What igniter fits my Goodman furnace?

The correct replacement for Goodman model WFM18045S3AXCB — 20165703S 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 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 (HSI) is a genuine OEM ignition component for the WFM18045S3AXCB furnace and compatible Goodman/Amana gas furnaces. When the thermostat calls for heat, the control board energizes this ignitor until it glows red-hot, lighting the burners. A failed or cracked ignitor is one of the most common causes of a furnace that won't produce heat.

Part number: 20165703S
Type: Hot surface ignitor (silicon-nitride style)
Voltage: 120V
Function: Burner ignition
Fit: WFM18045S3AXCB and compatible Goodman furnaces

OEM vs. Generic: The OEM 20165703S is a rugged silicon-nitride element with the correct resistance, mounting bracket, and connector for a direct fit. Generic universal ignitors require adapting the bracket and wiring and often have shorter service lives. For a reliable, no-fuss repair, OEM is the safe choice.

Install difficulty: Easy to moderate — typically one or two mounting screws and a single plug connector. Handle only by the ceramic base, never the fragile element. Shut off power first. 15–30 minutes for most techs and confident DIYers.
