The Goodman 20165703S Hot Surface Ignitor is a genuine OEM ignition component for the Goodman WFM18090S5CXCB gas furnace. When the control board calls for heat, the ignitor element heats to a glowing temperature to light the main burners. Hot surface ignitors are a wear item — the brittle element degrades over thousands of heating cycles — and a cracked or open ignitor is the leading cause of a furnace that clicks but produces no flame.

Specifications

OEM Part Number: 20165703S
Part Type: Hot Surface Ignitor (HSI)
Compatible Model: WFM18090S5CXCB
Brand: Goodman
Equipment: Gas Furnace
Function: Electrically heated element that lights the main burners

OEM vs. Generic

This OEM Goodman ignitor arrives with the correct mounting bracket, harness, and connector so it plugs directly into your furnace with no adapters. Generic universal ignitor kits require bracket bending and wire splicing, and their resistance may not match the board's timing, shortening service life. OEM delivers a true drop-in replacement.

Installation Difficulty

Rating: Easy. Shut off power, unplug the ignitor connector, remove one or two mounting screws, and install the new unit. Handle the element by the ceramic base only — skin oils shorten its life. Typically 15–20 minutes.
