The Goodman 20165703S Hot Surface Igniter is the genuine OEM ignition source for the WFM18115S5CXCB gas furnace. When the thermostat calls for heat and draft is proven, the control board energizes this igniter until it glows red-hot, lighting the burners cleanly and reliably. A weak or cracked igniter is the single most common cause of no-heat furnace calls, making this an essential repair and spare part.

OEM vs. Generic

The OEM 20165703S matches the correct resistance, glow profile, and mounting geometry for your furnace. Universal aftermarket igniters require adapter kits and often fail prematurely from improper positioning in the flame path. OEM ensures consistent light-off and longer service life.

Install Difficulty

Moderate (3/5). Kill power, unplug the igniter connector, remove the mounting screw, and install the new unit — handle the ceramic element by the bracket only, never touch the glow area, as skin oils cause hot-spot failure. Roughly 20 minutes.
