Specifications

Part Number: 20165703S
Type: Hot surface igniter (HSI)
Function: Electric burner ignition
Fit: Goodman WFM18090S4BXCC furnace

OEM vs. Generic

This genuine OEM igniter matches the original resistance, mounting bracket, and connector, so it drops in without adapters or rewiring. Generic silicon-nitride or carbide replacements sometimes require harness splicing and may vary in warm-up time or lifespan. Choosing OEM ensures correct ignition timing and reliable cold-weather starts.

Install Difficulty

Easy (2/5). Replacement involves shutting off power and gas, unplugging the connector, removing one or two mounting screws, and installing the new igniter — handle only by the ceramic base, never the fragile element. Most homeowners can complete this in 15–20 minutes; call a pro if you are uncomfortable working near the burner assembly.
