The Goodman 20165703S Hot Surface Ignitor (HSI) is a genuine OEM ignition element for the WFD18070S3AXCB gas furnace and compatible Goodman/Amana models. When the thermostat calls for heat, the control board energizes this ignitor to glow red-hot, lighting the burners. A cracked or worn ignitor is the single most common cause of a no-heat / no-ignition failure.

Specifications

OEM Part Number: 20165703S
Type: Hot surface ignitor (durable silicon-nitride style element)
Voltage: 120V furnace ignition circuit
Function: Direct-ignition of gas burners on heat call
Fitment: Goodman WFD18070S3AXCB and compatible furnaces

OEM vs. Generic

Generic ignitors vary widely in resistance and warm-up time, which can cause delayed ignition, gas-valve timeouts, or premature failure. This genuine OEM ignitor is matched to your furnace's ignition sequence and built to survive thousands of heating cycles. For a reliable, long-lasting repair, OEM is the recommended choice.

Installation

Difficulty: Moderate (2/5). Kill power at the disconnect, disconnect the ignitor plug, remove the mounting screw, and slide the new element in without touching the fragile silicon-nitride tip with bare fingers. Most repairs take 15–20 minutes. Handle by the ceramic base only.
