OEM Carrier Hot Surface Igniter 48GS400168 for Model PY3PPA060115AB

This is the OEM factory-specified hot surface igniter (spark electrode ignitor) for the Carrier PY3PPA060115AB packaged gas/electric unit. The igniter is the first critical component in the heating sequence — on a call for heat, the control board energizes the igniter, which must reach ignition temperature before the gas valve opens. When this igniter fails or cracks, the furnace section will attempt ignition, fail to prove flame, and lock out — leaving you with no heat and a blinking fault code on the control board.

• Specs: OEM Part Number 48GS400168 | Type: Spark Electrode / Hot Surface Igniter | Factory-matched geometry and lead length for direct drop-in fit on Carrier PY3PPA060115AB | Rated for high-cycle commercial and residential packaged applications
• OEM vs Generic: This is the genuine Carrier OEM igniter — identical in material composition, element geometry, and wiring harness connector to what was installed at the factory. Generic igniters may differ in tip angle or mounting hole spacing, risking misfire or premature failure.
• Install Difficulty: 3/5 — Shut off gas supply and 24V/line voltage power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (to verify open-circuit resistance, typically 40–200Ω for silicon nitride). Handle igniter body only — skin oils on the element cause hot spots and early cracking.
• Warranty: 1-year OEM factory warranty against defects. In-stock in our warehouse — ships same business day when ordered before 3 PM EST.
