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.

The Goodman 20165703S Hot Surface Ignitor is a genuine OEM ignition component for the WFM18070S4BXCC gas furnace and compatible Goodman/Amana models. The hot surface ignitor (HSI) glows to a high temperature on a call for heat and ignites the burner gas — it replaces the older standing-pilot system for faster, more efficient lightoff. HSIs are wear items: the element becomes brittle over thousands of heating cycles and eventually cracks, producing a furnace that runs the inducer and clicks the valve but never lights.

OEM Part Number: 20165703S
Fits Model: WFM18070S4BXCC
Type: Hot surface ignitor (HSI)
Element: High-temperature silicon-based igniter
Application: Gas furnace burner ignition

OEM vs. Generic

This is the factory ignitor matched to your furnace's mounting bracket, connector, and voltage/resistance profile. Universal HSI kits exist, but mismatched resistance or bracket geometry can lead to slow lightoff, incomplete glow, or premature failure. Given how fragile these elements are, starting with the correct OEM 20165703S avoids repeat service calls.

Install Difficulty: Easy

Typically a one- or two-screw job, 15–20 minutes. Cut power, unplug the ignitor harness, remove the mounting screws, and lift the old ignitor out of the burner assembly. Never touch the ceramic or element with bare fingers — skin oils create hot spots that shorten its life. Seat the new ignitor, secure it, and reconnect.
