OEM Carrier Spark Electrode Hot Surface Igniter 48GS400168 for Model PY3PPA036060NB

This OEM spark electrode igniter (part# 48GS400168) is the factory-specified replacement for the Carrier PY3PPA036060NB packaged gas unit. The hot surface igniter is the first component activated in every heating cycle — the control board energizes it to reach ignition temperature, after which the gas valve opens and combustion begins. When the igniter cracks, weakens, or fails entirely, the burner will not light and the furnace section enters a lockout fault. Common symptoms include a no-heat call, the system attempting ignition 2–3 times before locking out, or a visible crack on the igniter element during inspection.
