What igniter fits my Goodman furnace?

The correct replacement for Goodman model WFD18070S3AXCC — 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 WFD18070S3AXCC — 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 (HSI) is a genuine OEM replacement for the WFD18070S3AXCC gas furnace. This ignitor glows red-hot when energized by the control board and lights the burners at the start of each heating cycle. A cracked or worn HSI is the single most common cause of a no-heat call: the inducer runs, the gas valve tries to open, but the burners never light and the furnace locks out. Swapping this part restores dependable ignition.

Specifications

OEM Part Number: 20165703S
Type: Hot surface ignitor (HSI)
Operating Voltage: 120V line-voltage ignitor
Element: High-durability ignitor material with ceramic base and mounting bracket
Compatibility: Goodman/Amana WFD18070S3AXCC and related furnaces

OEM vs. Generic

Universal ignitor kits require adapting the bracket and splicing the harness, and their resistance can differ from spec — which shortens life and risks failed ignition. This OEM 20165703S arrives with the correct bracket and connector for the WFD18070S3AXCC, so it plugs in directly and matches the board's ignition timing. The brittle silicon-carbide element is also easily cracked by rough handling; buying the exact factory part avoids install-time breakage.

Installation Difficulty: Easy to Moderate

About 20–30 minutes. Cut power, unplug the two-pin connector, remove the mounting screw, and lift out the old ignitor. Handle the new element by the ceramic base only — never touch the glowing element with bare fingers. Seat it at the correct depth in the burner, reconnect, and test a full ignition cycle.
