OEM Carrier Hot Surface Igniter (Spark Electrode) for Model PY4GNAB60090NA — Part #48VL400002

This is the factory OEM hot surface igniter (spark electrode) for the Carrier PY4GNAB60090NA packaged gas unit. The igniter is the first component to act in every heating cycle — it heats to approximately 2,500°F to ignite the gas burner. When it fails, the control board will attempt ignition, detect no flame, and trigger a lockout — leaving you with a system that attempts to start but delivers no heat. If your unit is locking out after 1–3 ignition trials, a cracked or failed igniter is the most common cause.

• OEM Part Number: 48VL400002 | Carrier factory-original spark electrode ignitor | Direct drop-in replacement with no modification required
• OEM vs Generic: OEM igniters are manufactured to exact resistance and thermal-shock specifications for your Carrier control board. Generic substitutes often have mismatched resistance values, causing nuisance lockouts or premature failure within one heating season.
• Install Difficulty: 2/5 — Straightforward swap accessible from the burner compartment. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Important: Never touch the igniter element with bare hands — skin oils cause hot spots and early cracking. Use gloves or handle by the bracket only.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
