OEM Carrier Spark Electrode Ignitor for Model PY3GEAA42060NA (Part# 48VL400002)

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY3GEAA42060NA packaged unit. The spark electrode ignitor generates the high-voltage arc that initiates combustion in the burner assembly. When the ignitor fails or degrades, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with no heat and a blinking fault code. Common failure symptoms include the unit cycling repeatedly without heat, an audible click with no ignition, or a hard lockout requiring a manual reset.

• Part Numbers: OEM part# 48VL400002 | Current superseding OEM part# 50HJ403022 — direct factory replacement with no modification required
• OEM vs Generic: This is a genuine Carrier factory-authorized ignitor manufactured to exact electrode gap and ceramic insulator specifications. Generic igniters often feature inconsistent electrode geometry, leading to weak spark, nuisance lockouts, and shortened service life in high-cycle applications.
• Install Difficulty: 2/5 — Shut off gas and power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify 24V control signal. Photograph wiring harness connector orientation before disconnecting. Handle ceramic insulator carefully — do not apply hand oils to the electrode tip.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PY3GEAA42060NA packaged gas/electric unit. Note that OEM part 48VL400002 has been superseded by Carrier part# 50HJ403022 — both are fully interchangeable. Always verify the part number against your unit's data plate before ordering. Have questions about fitment? Our HVAC parts specialists confirm compatibility before you buy.
