OEM Carrier Hot Surface Igniter (Spark Electrode) 48GS400168 for Model PY3PEA042060AB

This OEM hot surface igniter (spark electrode) is the factory-specified replacement for the Carrier PY3PEA042060AB packaged heating and cooling unit. The igniter is the first critical component in the gas ignition sequence — it heats to over 1800°F to reliably light the burner each heating cycle. When the igniter fails, the control board detects no flame after the ignition attempt and locks out the furnace, leaving you with no heat. Common symptoms include repeated no-heat lockout codes, a furnace that attempts to start then shuts off, or a visibly cracked or broken igniter element.

• Specs: Spark electrode ignitor | OEM Part# 48GS400168 | Factory-matched geometry and lead wire length for direct, no-modification installation
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact material and dimensional specifications. Generic igniters often vary in element composition and mounting angle, causing nuisance lockouts and shortened service life — especially in packaged rooftop applications exposed to wide temperature swings.
• Install Difficulty: 2/5 — Always disconnect power and shut off gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Do not touch the igniter element with bare hands — skin oils cause hot spots that crack the element prematurely. Use clean gloves or handle by the bracket only.
• Warranty: 1-year OEM factory warranty against defects. Orders placed by 3PM local time ship same business day from our warehouse.
