The correct replacement for Goodman model WFM18140S5DNCB — 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.

Goodman 20165703S Hot Surface Ignitor

The 20165703S is a genuine Goodman hot surface ignitor (HSI) designed as a direct OEM replacement for the WFM18140S5DNCB gas furnace and compatible Goodman/Amana models. On each call for heat, the control board energizes this ignitor until it glows red-hot, lighting the burners. A cracked or worn ignitor is the single most common cause of intermittent no-heat and ignition-lockout faults.

Specifications

Part number: 20165703S
Type: Hot surface ignitor (HSI)
Brand: Goodman / Amana OEM
Application: WFM18140S5DNCB and compatible gas furnaces
Mount: Direct-fit bracket to match original

OEM vs. Generic

This factory OEM Goodman ignitor matches the correct resistance, element geometry, and bracket so it seats properly and ignites on the first cycle. Universal ignitor kits require adapters and can be fragile or mismatched to your control board's timing. For dependable cold-weather starts, OEM is the safer choice.

Installation Difficulty

Easy (2/5). Usually a 15–20 minute job with one or two screws and a single connector. Handle the ceramic/silicon element by the bracket only — skin oils and touching the element shorten its life. Cut power before servicing.
