OEM Carrier Hot Surface Igniter (48GS400168) for Model PY1PNB036090AAAA

This is the OEM factory-specified hot surface igniter (spark electrode ignitor) for the Carrier PY1PNB036090AAAA packaged unit. The igniter is responsible for lighting the burner assembly during each heating cycle. When it fails — whether through cracking, carbon buildup, or an open circuit — the control board will attempt ignition, detect no flame, and lock out the system. The result is a furnace or packaged unit that runs the inducer and clicks through a cycle but produces no heat. Replacing the igniter with a genuine OEM part restores factory ignition timing and ensures compatibility with your control board's voltage profile.

• Specs: OEM Part Number 48GS400168 | Spark Electrode Ignitor design | Factory-matched to Carrier PY1PNB036090AAAA control board voltage and timing sequence
• OEM vs Generic: Genuine Carrier OEM igniters are manufactured to exact resistance and geometry tolerances. Aftermarket igniters can vary in tip angle and element resistance, causing delayed ignition, nuisance lockouts, or premature failure within one heating season.
• Install Difficulty: 3/5 — Gas is involved; always shut off the gas supply and 24V control power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (to verify open circuit on old igniter). Never touch the ceramic element with bare hands — skin oils cause hot spots and early failure.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY1PNB036090AAAA packaged unit. Always cross-reference the part number on your existing igniter or the unit's wiring diagram before ordering. Our fitment specialists are available to verify compatibility before you buy — same-day shipping available when you order now.
